The Km for soluble arabinoxylan in the absence of inhibitor is 20+/-2 mg/ml with a kcat of 103+/-6 s-1. The kinetics of the inhibition of this reaction are competitive, with a Ki value of 0.35 microM, showing that the inhibitor binds at or close to the active site of free xylanase. This report describes the first isolation of a xylanase inhibitor from any organism.  (+info)

Purification of gibberellic acid-induced lysosomes from wheat aleurone cells. (2/3819)

Using isopycnic density gradient centrifugation, lysosomes were concentrated in a single region of a sucrose-Ficoll gradient (p = 1-10 g cm-3), well separated from most other cell organelles. Gibberellic acid-induced lysosomes were found to be rich in alpha-amylase and protease but not ribonuclease. The lysosomal band also contained a majority of the NADH2-cytochrome c reductase, a marker enzyme for endoplasmic reticulum, found in the gradient. Examination of electron micrographs revealed that a purified band of lyosomes contained at least 3 vesicle types, ranging in size from 0-1 to 0-5 mum. The significance of these findings to proposed mechanisms of action of gibberellic acid is discussed.  (+info)

Evolutionary dynamics of Ty1-copia group retrotransposons in grass shown by reverse transcriptase domain analysis. (3/3819)

The evolutionary dynamics of Ty1-copia group retrotransposons in grass were examined by reverse transcriptase (RT) domain analysis. Twenty-three rice RT sequences were newly determined for this report. Phylogenetic analysis of 177 RT sequences, mostly derived from wheat, rice, and, maize, showed four distinct families, which were designated G1, G2, G3, and G4. Three of these families have elements obtained from distantly related species, indicative of origins prior to the radiation of grass species. Results of Southern hybridization and detailed comparisons between the wheat and rice sequences indicated that each of the families had undergone a distinct pattern of evolution. Multiple families appear to have evolved in parallel in a host species. Analyses of synonymous and nonsynonymous substitutions suggested that there is a low percentage of elements carrying functional RT domains in the G4 family, indicating that the production of new G4 elements has been controlled by a small number of elements carrying functional RT domains.  (+info)

The influence of a diet rich in wheat fibre on the human faecal flora. (4/3819)

The effect on the faecal flora of adding wheat fibre to a controlled diet in four healthy volunteers for a 3-week period has been observed. No change in the concentration of the bacteria in the bacterial groups counted was found, although there was a slight increase in total output associated with increased faecal weight. The predominant organisms in all subjects were non-sporing anaerobes, but the dominant species in each subject was different and was unaffected by changing the diet. Similarly, the concentration of faecal beta-glucuronidase detected in two subjects was unaltered and the concentration of clostridia able to dehydrogenate the steroid nucleus found in one subject was unaltered. It is suggested that the faecal microflora is not primarily controlled by the presence of undigested food residues in the large bowel.  (+info)

Physical and functional heterogeneity in TYMV RNA: evidence for the existence of an independent messenger coding for coat protein. (5/3819)

Turnip yellow mosaic virus RNA can be separated into two distinct components of 2 times 10(6) and 300 000 daltons molecular weight after moderate heat treatment in the presence of SDS or EDTA. The two species cannot have arisen by accidental in vitro degradation of a larger RNA, as they both possess capped 5' ends. Analysis of the newly synthesized proteins resulting from translation of each RNA by a wheat germ extract shows that the 300 000 molecular weight RNA can be translated very efficiently into coat protein. When translated in vitro the longer RNA gave a series of high molecular weight polypeptides but only very small amounts of a polypeptide having about the same mass as the coat protein. Thus our results suggest that the small RNA is the functional messenger for coat protein synthesis in infected cells.  (+info)

Genetic selection of mutations in the high affinity K+ transporter HKT1 that define functions of a loop site for reduced Na+ permeability and increased Na+ tolerance. (6/3819)

Potassium is an important macronutrient required for plant growth, whereas sodium (Na+) can be toxic at high concentrations. The wheat K+ uptake transporter HKT1 has been shown to function in yeast and oocytes as a high affinity K+-Na+ cotransporter, and as a low affinity Na+ transporter at high external Na+. A previous study showed that point mutations in HKT1, which confer enhancement of Na+ tolerance to yeast, can be isolated by genetic selection. Here we report on the isolation of mutations in new domains of HKT1 showing further large increases in Na+ tolerance. By selection in a Na+ ATPase deletion mutant of yeast that shows a high Na+ sensitivity, new HKT1 mutants at positions Gln-270 and Asn-365 were isolated. Several independent mutations were isolated at the Asn-365 site. N365S dramatically increased Na+ tolerance in yeast compared with all other HKT1 mutants. Cation uptake experiments in yeast and biophysical characterization in Xenopus oocytes showed that the mechanisms underlying the Na+ tolerance conferred by the N365S mutant were: reduced inhibition of high affinity Rb+ (K+) uptake at high Na+ concentrations, reduced low affinity Na+ uptake, and reduced Na+ to K+ content ratios in yeast. In addition, the N365S mutant could be clearly distinguished from less Na+-tolerant HKT1 mutants by a markedly decreased relative permeability for Na+ at high Na+ concentrations. The new mutations contribute to the identification of new functional domains and an amino acid in a loop domain that is involved in cation specificity of a plant high affinity K+ transporter and will be valuable for molecular analyses of Na+ transport mechanisms and stress in plants.  (+info)

Cloning and expression of a wheat (Triticum aestivum L.) phosphatidylserine synthase cDNA. Overexpression in plants alters the composition of phospholipids. (7/3819)

We describe the cloning of a wheat cDNA (TaPSS1) that encodes a phosphatidylserine synthase (PSS) and provides the first strong evidence for the existence of this enzyme in a higher eukaryotic cell. The cDNA was isolated on its ability to confer increased resistance to aluminum toxicity when expressed in yeast. The sequence of the predicted protein encoded by TaPSS1 shows homology to PSS from both yeast and bacteria but is distinct from the animal PSS enzymes that catalyze base-exchange reactions. In wheat, Southern blot analysis identified the presence of a small family of genes that cross-hybridized to TaPSS1, and Northern blots showed that aluminum induced TaPSS1 expression in root apices. Expression of TaPSS1 complemented the yeast cho1 mutant that lacks PSS activity and altered the phospholipid composition of wild type yeast, with the most marked effect being increased abundance of phosphatidylserine (PS). Arabidopsis thaliana leaves overexpressing TaPSS1 showed a marked enhancement in PSS activity, which was associated with increased biosynthesis of PS at the expense of both phosphatidylinositol and phosphatidylglycerol. Unlike mammalian cells where PS accumulation is tightly regulated even when the capacity for PS biosynthesis is increased, plant cells accumulated large amounts of PS when TaPSS1 was overexpressed. High levels of TaPSS1 expression in Arabidopsis and tobacco (Nicotiana tabacum) led to the appearance of necrotic lesions on leaves, which may have resulted from the excessive accumulation of PS. The cloning of TaPSS1 now provides evidence that the yeast pathway for PS synthesis exists in some plant tissues and provides a tool for understanding the pathways of phospholipid biosynthesis and their regulation in plants.  (+info)

Plant cell-directed control of virion sense gene expression in wheat dwarf virus. (8/3819)

We have used particle bombardment (biolistics) to deliver replication-competent wheat dwarf virus (WDV)-based constructs, carrying reporter gene sequences fused to the virion sense promoter (Pv) or the CaMV 35S promoter, to suspension culture cells and immature zygotic embryos of wheat. While the replication of WDV double-stranded DNA forms (replicons) was equivalent between wheat suspension culture cells and embryos, GUS reporter gene activity was 20-40 times higher in the embryo cultures. Maximum expression of WDV replicons occurred in the embryonic axis tissue of wheat embryos but their expression in suspension cells was compromised, compared with transiently maintained input plasmid DNA containing the same sequences. From these studies, we propose that WDV replicons are subject to a host cell-controlled competency for virion sense transcription. The term competency is used to distinguish between the phenomenon described here and control of gene expression by specific transcription factors. Control of competency is independent of Pv, the replacement 35S promoter and of the complementary sense control of virion sense expression involving specific sequences in Pv. We propose that factors controlling the competency for replicon expression may be present in cells which, as well as maintaining high rates of DNA synthesis, are totipotent. Cell type control of active chromatin, methylation of specific sequences in WDV minichromosomes and/or interaction of virus-encoded proteins with specific host factors are considered as possible mechanisms.  (+info)

Synthetic hexaploid wheats (SHWs) are an important component of the breeding programs of the International Maize and Wheat Improvement Center (CIMMYT). CIMMYT germplasm is the most important source of genetic resources for wheat breeding programs in Iran, but their utilization has to be examined prior to their incorporation into breeding programs. This study was conducted to evaluate the resistance of 128 CIMMYT SHWs to septoria tritici blotch (STB), a destructive wheat disease caused by Zymoseptoria tritici. Wheat seedlings were inoculated with Z. tritici spores in the greenhouse, kept at 20-22ºC and scored 21 days post inoculation by estimating the percentage of necrotic lesions bearing pycnidia. Inter simple sequence repeat (ISSR) markers revealed that 11 Z. tritici isolates had high genetic variability. The isolates varied in their virulence towards SHWs. Among all interactions (n=1408), 304 resistance responses were identified. Of 128 genotypes, 60 synthetic hexaploid wheat genotypes showed no
As food crop, wheat is of prime importance for human society. Nevertheless, our understanding of the genetic and molecular mechanisms controlling wheat productivity conditions has been, so far, hampered by the lack of sufficient genomic resources. The present work describes the isolation and characterization of TdERF1, an ERF gene from durum wheat (Triticum turgidum L. subsp. durum). The structural features of TdERF1 supported the hypothesis that it is a novel member of the ERF family in durum wheat and, considering its close similarity to TaERF1 of Triticum aestivum, it probably plays a similar role in mediating responses to environmental stresses. TdERF1 displayed an expression pattern that discriminated between two durum wheat genotypes contrasted with regard to salt-stress tolerance. The high number of cis-regulatory elements related to stress responses present in the TdERF1 promoter and the ability of TdERF1 to regulate the transcription of ethylene and drought-responsive promoters clearly ...
Emmer wheat as the progenitor of common wheat, holds the genetic potentiality for improvement of wheat yield, quality and stress tolerance such as drought and salt. To comprehensively evaluate the salt tolerance of emmer wheat, a total of 30 traits including growth, physiology and photosynthesis related as well as K+ and Na+ content of 30 wild emmer and 14 durum wheat accessions were systematically investigated and compared between normal and saline conditions. Salt tolerance index (STI) based on multiple regression analysis of these traits was calculated and five wild emmer accessions showed high salt tolerance, which could be used as valuable resource for wheat salt tolerance improvement. Furthermore, wild emmer genotypes showed wider trait performance variation compared to durum wheat, indicating the higher genetic diversity in wild emmer wheat. Then, shoot Na+ content, shoot K+/Na+ ratio, root length and root surface area were identified as suitable indexes for salt tolerance evaluation. Na+
Background: Triticum monococcum (2n) is a close ancestor of T. urartu, the A-genome progenitor of cultivated hexaploid wheat, and is therefore a useful model for the study of components regulating photomorphogenesis in diploid wheat. In order to develop genetic and genomic resources for such a study, we constructed genome-wide transcriptomes of two Triticum monococcum subspecies, the wild winter wheat T. monococcum ssp. aegilopoides (accession G3116) and the domesticated spring wheat T. monococcum ssp. monococcum (accession DV92) by generating de novo assemblies of RNA-Seq data derived from both etiolated and green seedlings. Principal Findings: The de novo transcriptome assemblies of DV92 and G3116 represent 120,911 and 117,969 transcripts, respectively. We successfully mapped ~90% of these transcripts from each accession to barley and ~95% of the transcripts to T. urartu genomes. However, only ~77% transcripts mapped to the annotated barley genes and ~85% transcripts mapped to the annotated T. ...

WRKY transcription factors are involved in multiple aspects of plant growth, development and responses to biotic stresses. Although they have been found to play roles in regulating plant responses to environmental stresses, these roles still need to be explored, especially those pertaining to crops. Durum wheat is the second most widely produced cereal in the world. Complex, large and unsequenced genomes, in addition to a lack of genomic resources, hinder the molecular characterization of tolerance mechanisms.This paper describes the isolation and characterization of five TdWRKY genes from durum wheat (Triticum turgidum L. subsp. Durum). A PCR-based screening of a T. turgidum BAC genomic library using primers within the conserved region of WRKY genes resulted in the isolation of five BAC clones. Following sequencing fully the five BACs, fine annotation through Triannot pipeline revealed 74.6% of the entire sequences as transposable elements and a 3.2% gene content with genes organized as islands within
The endosperm part of the durum wheat is very hard. This can significantly reduce our intake of fructans and lower our overall level of FODMAPs. Durum is the hardest of the hard wheats and is amber in color and larger than those of other wheat varieties.

Global nitrogen use efficiency (NUE) for cereal production is marginal and is estimated to be about 33%. Remote sensing tools have tremendous potential for improving NUE in crops through efficient nitrogen management as well as the identification of high-NUE genotypes. The objectives of this study were (i) to identify and quantify the variation in NUE across 24 winter wheat genotypes (Triticum aestivum L.) and (ii) to determine if the normalized difference vegetation index (NDVI) could characterize the variability in NUE across wheat genotypes. This study was conducted in 2010 and 2011 in the semi-arid climate of Northeastern Colorado across dryland and irrigated conditions. Our results indicate significant variation in the NUE among genotypes across two irrigation conditions. We observed a strong relationship between the NDVI and NUE-as PFP (partial factor productivity) and PNB (partial nitrogen balance)-across the 24 wheat genotypes under dryland conditions (average R2 for PFP and PNB = 0.84) at
Abstract. Climate change is exerting significant impacts on global agricultural production. Climatic variations adversely affect crop production and, thus tend to impose a key constraint of agricultural production, primarily on how to cont inuously enhance the winter wheat yields worldwide. The high uncertainties in predicting the effects of climate change on wheat production are most likely due to rare understanding on the responses of wheat production to extreme climatic factors, e.g. high temperatures, low humidity as well as high wind speed. Dry-hot wind hazard represents one of the main natural disasters for Chinese winter wheat production, especially for the Huang-huai-hai plain. However, high uncertainties of the effects of dry-hot wind hazard on winter wheat production still exist, mainly due to the gaps of long-term observations. Therefore, we selected Shangqiu as the case study area to determine the occurrence regularity of dry-hot wind hazard on winter wheat production in ...
Genetic diversity assessment is necessary to help tackle the threats of environmental fluctuations and for the effective exploitation of genetic resources in breeding program. Recent advancement in the field of molecular markers has made the genetic characterization of genotypes rapid, reliable and reproducible. In the present investigation, we have characterized 49 wheat genotypes at molecular level using 52 SSR primers (including Yr specific primers). 27 polymorphic SSR markers were dispersed over the AABBDD wheat genome, a total of 102 alleles were detected with allele range of 1 to 6. Polymorphism information content (PIC) values calculated to assess the informativeness of each marker ranged from 0.11 to 0.95 and there is significant that 5 out of 27 SSR loci, namely Xpsp 3000, Xwgp249, Wmc198, csLV34, Xgwm301 revealed PIC values above 0.70, can be considered highly useful for differentiation of wheat genotypes. The UPGMA cluster tree analysis led to the grouping of 49 wheat genotypes in two major
Many ecological regions of Turkey are suitable for the production of durum wheat, and therefore the yield and quality of this wheat should be improved. In this study, stability properties associated with the pasta quality of 25 durum wheat (Triticum durum Desf.) genotypes grown in 3 different locations (Tokat-Kazova, Diyarbakir, and Sivas-Ulas) for 2 years (2005-2006, 2006-2007) were investigated. Durum wheat genotypes were composed of 12 registered varieties and 13 advanced experimental lines. Field trials were conducted in a randomized complete block design with 3 replications. Protein content, gluten index, sedimentation and specific sedimentation volumes, yellow pigment content, and lipoxygenase activity of the durum wheats were measured as major quality characteristics. The regression coefficient (b(i)) and mean square of deviation from regression (S(d)(2)) were employed as the stability parameters. Genotypes, growing environments, and their interactions were found to be statistically ...
Key Results Recombination in the gametes of the F₁ hybrids was at a level where it was possible to generate a genetic linkage map of Ae. speltoides. This was used to identify 294 wheat/Ae. speltoides introgressions. Introgressions from all seven linkage groups of Ae. speltoides were found, including both large and small segments. Comparative analysis showed that overall macro-synteny is conserved between Ae. speltoides and T. aestivum, but that Ae. speltoides does not contain the 4A/5A/7B translocations present in wheat. Aegilops speltoides has been reported to carry gametocidal genes, i.e. genes that ensure their transmission through the gametes to the next generation. Transmission rates of the seven Ae. speltoides linkage groups introgressed into wheat varied. A 100 % transmission rate of linkage group 2 demonstrates the presence of the gametocidal genes on this chromosome ...
An ordered draft sequence of the 17-gigabase hexaploid bread wheat (Triticum aestivum) genome has been produced by sequencing isolated chromosome arms. We have annotated 124,201 gene loci distributed nearly evenly across the homeologous chromosomes and subgenomes. Comparative gene analysis of wheat subgenomes and extant diploid and tetraploid wheat relatives showed that high sequence similarity and structural conservation are retained, with limited gene loss, after polyploidization. However, across the genomes there was evidence of dynamic gene gain, loss, and duplication since the divergence of the wheat lineages. A high degree of transcriptional autonomy and no global dominance was found for the subgenomes. These insights into the genome biology of a polyploid crop provide a springboard for faster gene isolation, rapid genetic marker development, and precise breeding to meet the needs of increasing food demand worldwide. ...
[Objective] The study aimed to discuss the regulation action of La3+ in rare earth on the antioxidant enzyme activity of winter wheat seedlings under low-temperature stress.[Method] With the winter wheat variety Yongliang 4 as the tested material,5 concn.grads of La3+ at 5,10,20,30 and 40 mg/kg were set up to spray the wheat seedlings.The test method of simulating the low temperature chilling injury was used to study the regulatory effects of La3+ on SOD,POD and CAT activities in the leaves of winter wheat seedlings.[Result] In the 7 d of La3+ treatment and in the treatment with low temperature at 0,5 and 10 ℃,SOD activity in winter wheat was increased remarkably with the decrease of temperature and showed a trend of first rising and then falling with the La3+ treatment days.CAT and POD activities also showed a trend of first rising and then falling with the decrease of stress temperature and the increase of La3+ treatment days.After the winter wheat was treated with La3+ at 20 mg/kg under low
Wild relatives of wheat (Triticum aestivum) are important sources of genes for resistance to disease and insect pests. A collection of the wild tetraploid wheat species Triticum timopheevii var. araraticum was evaluated for reaction to Hessian fly (Mayetiola destructor), wheat curl mite (Eriophyes tulipae), and six foliar diseases: leaf rust (caused by Puccinia recondita f. sp. tritici), stem rust (caused by Puccinia graminis f. sp. tritici), stripe rust (caused by Puccinia striiformis), powdery mildew (caused by Blumeria graminis f. sp. tritici), tan spot (caused by Pyrenophora tritici-repentis), and Seploria blotch (caused by Septoria tritici). All accessions tested were resistant to Seploria blotch and a very high percentage were resistant to tan spot. Resistance was detected to four obligate fungal pathogens, although accessions with leaf rust resistance were more frequent in the collection than those with resistance to stripe rust, stem rust, or powdery mildew. Resistance to Hessian fly ...

Y1 - 1998/4. N2 - In the experiments the frost resistance of eight T. durum wheat varieties of various origins and of sixteen T. durum genotypes bred in Martonvásár was evaluated in the phytotron after freezing at -13°C and -15°C. In order to determine the degree of frost resistance the number of plants surviving freezing was recorded and each plant was scored on a 0-5 scale. For some of the T. durum genotypes tested in the freezing experiment the grain yield was also determined in field experiments. The bread wheat variety Mv 15, which has excellent frost resistance and was used as the control, exhibited approx. 94% survival at both freezing temperatures. When frozen at -15°C the varieties Odmadur 1, Odmadur 2 and Martondur 1 and many of the T. durum lines bred in Martonvásár showed ...
As with many grasses, polyploidy is common in wheat.[9] There are two wild diploid (non-polyploid) wheats, T. boeoticum and T. urartu. T. boeoticum is the wild ancestor of domesticated einkorn, T. monococcum.[10] Cells of the diploid wheats each contain 2 complements of 7 chromosomes, one from the mother and one from the father (2n=2x=14, where 2n is the number of chromosomes in each somatic cell, and x is the basic chromosome number). The polyploid wheats are tetraploid (4 sets of chromosomes, 2n=4x=28), or hexaploid (6 sets of chromosomes, 2n=6x=42). The tetraploid wild wheats are wild emmer, T. dicoccoides, and T. araraticum. Wild emmer is the ancestor of all the domesticated tetraploid wheats, with one exception: T. araraticum is the wild ancestor of T. timopheevi.[11] There are no wild hexaploid wheats, although feral forms of common wheat are sometimes found. Hexaploid wheats developed under domestication. Genetic analysis has shown that the original hexaploid wheats were the result of a ...

Due to the high polymorphisms between synthetic hexaploid wheat (SHW) and common wheat, SHW has been widely used in genetic studies. The transferability of simple sequence repeats (SSR) among common wheat and its donor species, Triticum turgidum and Aegilops tauschii, and their SHW suggested the possibility that some SSRs, specific for a single locus in common wheat, might appear in two or more loci in SHWs. This is an important genetic issue when using synthetic hexaploid wheat population and SSR for mapping. However, it is largely ignored and never empirically well verified. The present study addressed this issue by using the well-studied SSR marker Xgwm261 as an example. The Xgwm261 produced a 192 bp fragment specific to chromosome 2D in common wheat Chinese Spring, but generated a 176 bp fragment in the D genome of Ae. tauschii AS60. Chromosomal location and DNA sequence data revealed that the 176 bp fragment also donated by 2B chromosome of durum wheat Langdon. These results indicated that ...
Experiments were conducted to compare differences in P uptake characteristics between two winter wheat cultivars Stephens and Yamhill (Triticum aestivum L) as related to root morphologies. Root length, root surface area and mean root radius were compared. Plant roots and shoots were separately analyzed for P content. The cultivars were grown in a growth chamber with a 16 hour light period at 22° C and an 8 hour darkness at 16° C for approximately three weeks. A growth medium deficient only in P and with a pH high enough (6.4 to 6.6) to prevent Al toxicity was prepared by mixing a silt loam and a sand. Soil P variables were established by adding phosphoric acid (H₃PO₄) to the soil at rates of 0, 25 and 100 ug P g⁻¹ soil. The root growth rates of the cultivars were exponential with time. Stephens had more rapid root growth rate, greater root length and root surface area than Yamhill. There were no significant cultivar differences in root radius. Stephens had higher root to shoot ratio ...

The symptoms of tan spot of wheat, caused by Pyrenophora triticirepentis, include a tan necrosis component and an extensive chlorosis component. Since tan spot has become the major component of the leafspotting disease complex of wheat in western Canada, the need for resistant cultivars has increased. This study was conducted to determine whether the resistance to tan spot found in a diverse set of spring and winter wheat genotypes was due to resistance genes not previously reported. The genetic control of resistance to necrosis induced by P. triticirepentis race 1 and race 2 was determined, under controlled environmental conditions, for spring wheat genotypes Erik and 86ISMN 2137 and winter wheat genotypes Hadden, Red Chief, and 6B-365. Plants were inoculated at the two-leaf stage and disease reaction was assessed based on lesion type. Tests of the F1 and F2 generations, and of F2:3 and F2:8 families, indicated that one recessive gene controlled resistance to the necrosis component of tan spot ...
Wheat (Triticum aestivum L.) a principal traditional cereal crop in the highlands of Ethiopia and is produced exclusively under rain fed conditions at altitudes ranging from 1500 to 3000 m.a.s.l.. The field trial was conducted at farmers field at Kokate Mara Chare Kebele, Sodo Zuria Woreda, Wolaita Zone of South Ethiopia in the main rainy season of 2014. Five levels of nitrogen (0, 46, 69, 92 and 115 kg ha-1) and phosphorous (0, 10, 20, 30 and 40 kg ha-1) were used to evaluate productivity of wheat in response to NP fertilizers and to identify the most suitable NP rates for production of wheat of wheat under participatory approach by using Farmers Research Group (FRG). Wheat variety Digalo was used for the experiment in a factorial Randomized Complete Block Design (RCBD) with three replications. Application of nitrogen (N) fertilizer had very highly significantly influenced total biomass, grain and straw yields of wheat but the effect of P and its interaction with N were not significant on ...
Wheat is the most important host for cereal cyst nematode, Heterodera filipjevi. The wild relatives of wheat have important sources of resistance genes to cereal nematodes. Phenotypic and genotypic evaluations have important implications for breeding programs, hence in this study information on the reaction of wheat genotypes to H. filipjevi and their genetic relationships are provided. A total of 223 wheat genotypes originating mostly from West Asia and North Africa (WANA countries) were evaluated against the H. filipjevi. Genetic diversity of 188 genotypes were assessed by using a 152 K single nucleotide polymorphism (SNP) chip. Data were analysed using generalized linear model, showed that there are significant differences at P

A new gene for Ug99 resistance from wheat landrace PI 374670 was detected on the long arm of chromosome 7A. Wheat landrace PI 374670 has seedling and field resistance to stem rust caused by Puccinia graminis f. sp tritici Eriks. & E. Henn (Pgt) race TTKSK. To elucidate the inheritance of resistance, 216 BC1F2 families, 192 double haploid (DH) lines, and 185 recombinant inbred lines (RILs) were developed by crossing PI 374670 and the susceptible line LMPG-6. The parents and progeny were evaluated for seedling resistance to Pgt races TTKSK, MCCFC, and TPMKC. The DH lines were tested in field stem rust nurseries in Kenya and Ethiopia. The DH lines were genotyped with the 90K wheat iSelect SNP genotyping platform. Goodness-of-fit tests indicated that a single dominant gene in PI 374670 conditioned seedling resistance to the three Pgt races. The seedling resistance locus mapped to the long arm of chromosome 7A and this result was verified in the RIL population screened with the flanking SNP markers using
We studied the effect of soft wheat seed treatment (Triticum aestivum L.) with two bacterial strains (Aeromonas media GS4 and Pseudomonas extremorientalis PhS1) isolated from earthworm coprolites on the growth and development of wheat seedlings in a 12-day laboratory experiment, as well as on root rot disease and the activity of guaiacol-dependant peroxidase under optimal conditions and abiotic stress (elevated and low temperatures and moisture content). We established that growing nonbacterized wheat plants under stress abiotic conditions reduced the height of plants compared to growing under optimal abiotic conditions, and seed bacterization with P. extremorientalis PhS1 strain increased wheat plant height (by 9-15%) under stress abiotic conditions compared to the nonbacterized plants.

The uptake of 137Cs and 90Sr by six varieties of spring wheat (Triticum aestivum) was compared in field trials on land contaminated by the Chernobyl accident. All the experimental varieties are officially adopted for agricultural use in Belarus and are used in large-scale production. Under identical conditions of nutrition, the productivity of the varieties varied significantly by a factor of 1.3. The extent of 137Cs and 90Sr accumulation by wheat grain, quantified as the concentration ratio, differed between the varieties by as much as a factor of 1.6, for both radionuclides. There was a significant linear positive correlation between the 90Sr activity concentration in grain and straw, and the calcium concentration. The correlation between 137Cs and potassium was not significant. The results suggest that certain varieties of spring wheat used in normal agricultural practice accumulate less 137Cs and 90Sr into grain than others. Some spring wheat varieties accumulated relatively less 137Cs, but ...
Napoleon is an amber durum wheat (Triticum turgidum L. var. durum) that meets the end-use quality specifications of the Canada Western Amber Durum wheat class. Napoleon was evaluated in the Durum Cooperative Test in 1996, 1997 and 1998 as DT484. Overall, Napoleon had significantly higher grain yield than all checks except AC Avonlea, and Napoleon had higher grain yields in the Black soil zone compared with the Brown soil zone. Napoleon had maturity similar to AC Morse and AC Avonlea, but was 1 d earlier maturing than Kyle and 2 d later maturing than Hercules. Napoleon was similar to AC Avonlea in height, but was significantly taller than AC Morse, and significantly shorter than Kyle and Hercules. Napoleon had lower lodging scores than Hercules and Kyle, but had higher lodging scores than AC Avonlea and AC Morse. Napoleon is resistant to leaf rust, stem rust, and common bunt, and moderately susceptible to loose smut, leaf spot and Fusarium head blight. Napoleon is the first low cadmium durum ...

Wild related species are a useful reservoir of valuable genes for widening the genetic base of wheat and for the reduction of the vulnerability of wheat cultivars to pathogens, fungal diseases and environmental hazards. In this work, the action of prezygotic and postzygotic incrossability barriers was characterized, determining the possibilities of direct introduction of Am - genome from Triticum monococcum and D-genome from Triticum. tauschii into T. aestivum cultivars, with elimination of commonly performed bridging hybridisation with tetraploid wheat. As gene recipient parents, Polish cultivars of hexaploid wheat cv. Omega, cv. Igna (spring) and cv. Tercja (winter) were used. Application of wheat cultivars as female parents in hybridisation with T. tauschii yielded a very low percentage of effective pollination (0-1.2%). In reciprocal crosses prezygotic incompatibility barriers were more weakly expressed, and percentages of effective pollination (i.e. pollination which initiates the first ...

Abiotic stress can alter key physiological constituents and functions in green plants. Improving the capacity to monitor this response in a non-destructive manner is of considerable interest, as it would offer a direct means of initiating timely corrective action. Given the vital role that plant pigments play in the photosynthetic process and general plant physiological condition, their accurate estimation would provide a means to monitor plant health and indirectly determine stress response. The aim of this work is to evaluate the response of leaf chlorophyll and carotenoid (C-t) content in wheat (Triticum aestivum L.) to changes in varying application levels of soil salinity and fertilizer applied over a complete growth cycle. The study also seeks to establish and analyze relationships between measurements from a SPAD-502 instrument and the leaf pigments, as extracted at the anthesis stage. A greenhouse pot experiment was conducted in triplicate by employing distinct treatments of both soil ...
Aegilops tauschii (2n=2 x=14, DD) is a rich source of genetic variability for hexaploid wheat (Triticum aestivum, 2n=6 x=42, AABBDD) improvement. This variability can be accessed through utilizing synthetic hexaploid wheat lines, which contain genomes from Ae. tauschii and T. turgidum (2n=4 x=28, AABB). Numerous desirable characteristics can and have been introgressed into common hexaploid wheat with this germplasm. In this work, the genetic variability in the two puroindoline genes (a and b) contained on the D genome, and the relationship that sequence polymorphisms in these genes have on endosperm texture among a population of 75 CIMMYT synthetic hexaploid accessions is described. Kernel texture was evaluated using the single kernel characterization system (SKCS). Kernel texture differed significantly (P=0.0001) among the synthetic hexaploid accessions (range 2.6 40.9) and the parent types, durum or Ae. tauschii. The interaction term between parent types was also a significant effect ...
Durum wheat [Triticum turgidum ssp. durum (Desf.) Husnot.], also known as pasta or macaroni wheat, is an allotetraploid (2n = 4x = 28, AABB genomes) of worldwide economic importance because it is used to make pasta and other semolina-based products. Durum wheat production is affected by numerous diseases. Among some of the most severe are the foliar diseases tan spot and SNB caused by the necrotrophic fungal pathogens P. tritici-repentis and Pa. nodorum, respectively. Both pathogens are members of the Pleosporales order of fungi and are known to produce NEs (Oliver et al. 2012; Faris et al. 2013 for reviews). When a specific NE is recognized by the corresponding host gene, a host defense response ensues, which leads to programmed cell death allowing these necrotrophs to penetrate, feed, and sporulate. The lack of NE recognition by the host leads to resistance. Therefore, these host-pathogen interactions operate in an inverse gene-for-gene manner (Wolpert et al. 2002; Friesen and Faris 2010; ...
Domestication has induced major genetic changes in crop plants to satisfy human needs and as a consequence of adaptation to agroecosystems. This adaptation might have affected root exudate composition, which can influence the interactions in the rhizosphere. Here, using two different soil types (sand, soil), we provide an original example of the impact of domestication and crop evolution on root exudate composition through metabolite profiling of root exudates for a panel of 10 wheat genotypes that correspond to the key steps in domestication of tetraploid wheat (wild emmer, emmer, durum wheat). Our data show that soil type can dramatically affect the composition of root exudates in the rhizosphere. Moreover, the composition of the rhizosphere metabolites is associated with differences among the genotypes of the wheat domestication groups, as seen by the high heritability of some of the metabolites. Overall, we show that domestication and breeding have had major effects on root exudates in the
Common bunt (CB) (Tilletia laevis and T. tritici) is a seed and soil borne disease that can cause significant quality and yield losses in wheat (Triticum aestivum). One of the most effective ways to control CB is with host resistance. To date, 15 resistance genes have been identified (Bt1 to Bt15). This study was conducted to evaluate previously identified molecular markers associated with Bt8, Bt10, Bt11, and Bt12 in 74 wheat genotypes of diverse origin. These lines included 15 isogenic CB differential lines, 24 lines with known Bt genes and the remaining lines were a mix of CB resistant and susceptible lines with unknown Bt genes. DNA was extracted from seed of each genotype and used for marker evaluation. A total of eight markers were evaluated for their association with Bt8, Bt10, Bt11, and Bt12, including four SSR markers Xgwm264, Xgwm374, and Xbarc128 for Bt12, three RAPD markers 372, 196, and FDS-RSA for Bt10, one SSR marker Xgwm114 for Bt11, and one RAPD marker Psg3 for Bt8. Xbarc128 was ...

The Major Threshability Genes Soft Glume (sog) and Tenacious Glume (Tg), of Diploid and Polyploid Wheat, Trace Their Origin to Independent Mutations at Non-Orthogous Loci. Theoretical and Applied Genetics. 119:341-351 Interpretive Summary: Wilde wheat species are difficult to thresh whereas our modern cultivated wheat varieties are easy to thresh. It is thought that threshability was an important trait for wheat to become a major grain crop for human consumption. The floret of wild wheat is enclosed by tough glumes that make spikes difficult to thresh, whereas cultivated wheat has soft glumes and is free-threshing. In this report, we identified the chromosome locations of the soft glume (sog)gene of a diploid wheat relative, Triticum monococcum and tenacious glume (Tg) gene of common wheat using chromosome-specific molecular markers. The sog gene was located close to the centromere on chromosome 2AS of T., monococcum whereas Tg was ...
A field experiment was conducted at the Seed and Plant Improvement Institute Research Field Station in Karaj, Iran, during the 2009-10 and 2010-11 growing seasons to estimate genetic progress and the variation in penological and agronomic characteristics in 13 irrigated facultative/winter bread wheat (Triticum aestivum L.) cultivars released in Iran between 1943 and 2011. Trends of temporal variation of the traits measured revealed that grain yield and some related phonological and agronomic traits have increased in the more recently released cultivars. Thousand grain weight decreased slightly compared to older cultivars. Number of days to heading and anthesis decreased in new cultivars, butgrain-filling period and days to physiological maturity did not change. Spike length also increased but plant height decreased in more recently released cultivars. These changes may explain the increase in grain yield of newly released facultative/winter bread wheat cultivars.
Durum wheat (Triticum turgidum L.) is a cereal crop widely grown in the Mediterranean regions; the amber grain is mainly used for the production of pasta, couscous and typical breads. Single nucleotide polymorphism (SNP) detection technologies and high-throughput mutation induction represent a new challenge in wheat breeding to identify allelic variation in large populations. The TILLING strategy makes use of traditional chemical mutagenesis followed by screening for single base mismatches to identify novel mutant loci. Although TILLING has been combined to several sensitive pre-screening methods for SNP analysis, most rely on expensive equipment. Recently, a new low cost and time saving DHPLC protocol has been used in molecular human diagnostic to detect unknown mutations. In this work, we developed a new durum wheat TILLING population (cv. Marco Aurelio) using 0.70-0.85 % ethyl methane sulfonate (EMS). To investigate the efficiency of the mutagenic treatments, a pilot screening was carried out on 1
Two durum wheat (Triticum durum Desf.) cultivars (Simeto and Ofanto) were grown in field trials in Foggia (Southern Italy), under two water regimes and in three cropping seasons, to evaluate the influence of water regime on grain protein composition in relation to technological quality. On grain samples, the following quality analyses were performed: protein and gluten content, gluten index and SDS test. Furthermore, different protein fractions were evaluated: gliadins; glutenins, high molecular weight subunits (HMW-GS) and low molecular weight subunits (LMW-GS) of the larger glutenin polymers; percentage of unextractable polymeric proteins (%UPP). Two-dimensional gel electrophoresis (2D) of glutenins was also performed on selected samples. A year-on-year variation in gluten index was observed and its values were positively correlated (r = 0.71**) with the number of days with maximum temperature ranging from 30 to 35 ◦C during grain filling. This was consistent with an increase in glutenin ...
The new virulent strain of the wheat stem rust disease (Ug99) is now confirmed to occur in Uganda, Kenya, Ethiopia, Sudan, Yemen and Iran. The regions of the Near East, Eastern Africa and Central and South Asia are at immediate risk and they account for some 37% of global wheat production. In most countries of these regions, wheat is the staple food crop, providing on average some 40% of the per capita calorie supply, and is especially important in the diets of the poorest. This new rust strain is highly virulent to almost all wheat varieties grown in these regions and most wheat varieties around the world. The risk of it causing global epidemics is very real and could result in devastating yield losses. Fortunately, from the results of coordinated and harmonized wheat rust field surveys undertaken in several countries and reported in late 2008, there are no indication of further movement of Ug99 to new countries, probably due to the droughts occurring in wheat-growing areas in Iran and some ...
The identification of genes of agronomic interest in bread wheat (Triticum aestivum L.) is hampered by its allopolyploid nature (2n = 6x = 42; AABBDD) and its very large genome, which is largely covered by transposable elements. However, owing to this complex structure, aneuploid stocks can be developed in which fragments or entire chromosomes are missing, sometimes resulting in visible phenotypes that help in the cloning of affected genes. In this study, the 2C gametocidal chromosome from Aegilops cylindrica was used to develop a set of 113 deletion lines for chromosome 3D in the reference cultivar Chinese Spring. Eighty-four markers were used to show that the deletions evenly covered chromosome 3D and ranged from 6.5 to 357 Mb. Cytogenetic analyses confirmed that the physical size of the deletions correlated well with the known molecular size deduced from the reference sequence. This new genetic stock will be useful for positional cloning of genes on chromosome 3D, especially for Ph2 affecting
DDC classification: 633.1194 Summary: Study of partial resistance components could produce useful information to develop better resistance to Septoria tritici in wheat (Triticurm aestivum). Inheritance of four partial resistance components: incubation period, latent period, leaf necrosis, and pycnidial density, was studied. Testing of Parent-l, Parent-2, F1, B1CFX, B2CF1, and F2 generations of six wheat crosses against two isolates of S. tritici indicated simple Mendelian inheritance of all components. Long incubation period seemed to be controlled by two complementary genes. Long latent period and low pycnidial density were each controlled by a single dominant gene. However, low leaf necrosis was controlled by one dominant gene in the genotype Vees/Snbs, by two dominant genes in the genotype Nasma*2/14-2, and by one dominant and one recessive gene in the genotype Saada. Phenotypic correlations among the four components of partial resistance indicated that leaf necrosis and pycnidial density ...
Recently, the wheat disease resistance gene Lr34 was cloned. Lr34 is a putative ABC transporter and provides non-specific, adult plant resistance to Puccinia triticina Eriks. (Krattinger et al, 2009. Science 323:1360). There is strong evidence that Lr34 enhances single resistance gene effects in wheat seedlings, and now that Lr34 has been cloned, this can be verified genetically. A cross between the isogenic wheat lines Thatcher Lr16 X Thatcher Lr16,34 was made, and 98 F2:6 near isogenic lines were evaluated for their response to Race 1 (BBBDB) of P. triticina in both seedlings and adult plants. Lines were scored for the presence or absence of Lr34 enhancement in seedlings and evaluated for adult plant resistance and leaf tip necrosis. Lr16 only lines had infection types of 2C while Lr16,34 lines had infection types of ;, 1. There are three known alleles of Lr34 and polymerase chain reaction primers are available for each. PCR reactions on the 98 NILs are in process, and the results will be ...
Genomic in situ hybridization (GISH) was used to study the nature of homoeologous chiasma formation in crosses between Triticum durum cv. Creso, homozygous for the ph1c mutation and Thinopyrum bessarabicum. The relative frequencies of wheat/wheat and wheat/Th. bessarabicum chiasma formation were determined. Pairing between apparently non-homologous Th. bessarabicum chromosomes was also observed. The potential of GISH as a tool for analysing homoeologous chiasma formation in wheat/alien hybrids is discussed. ...
