The yeast Xanthophyllomyces dendrorhous is used for the microbiological production of the antioxidant carotenoid astaxanthin. In this study, we established an optimal protocol for protein extraction and performed the first proteomic analysis of the strain ATCC 24230. Protein profiles before and during the induction of carotenogenesis were determined by two-dimensional polyacrylamide gel electrophoresis and proteins were identified by mass spectrometry. Among the approximately 600 observed protein spots, 131 non-redundant proteins were identified. Proteomic analyses allowed us to identify 50 differentially expressed proteins that fall into several classes with distinct expression patterns. These analyses demonstrated that enzymes related to acetyl-CoA synthesis were more abundant prior to carotenogenesis. Later, redox- and stress-related proteins were up-regulated during the induction of carotenogenesis. For the carotenoid biosynthetic enzymes mevalonate kinase and phytoene/squalene synthase, we observed
The potential of X. dendrorhous as a microbiological source of natural astaxanthin was recognized soon after the isolation of this yeast by Hermann Phaff and coworkers (21). So far, strategies to improve astaxanthin production in X. dendrorhous were based on classical mutagenesis and selection (2, 9, 13) and/or the improvement of fermentation conditions (4, 11). Here, we describe the use of recombinant DNA technology for metabolic engineering of the astaxanthin biosynthetic pathway in X. dendrorhous. The crtYB gene of X. dendrorhous encoding the chimeric phytoene synthase-lycopene cyclase was used to construct specific carotenoid biosynthetic mutants. The combination of a white phenotype and the resistance towards G418 and the results of a Southern blot analysis (Fig. 4) indicated a successful inactivation of the endogenous crtYB gene, by either a single or a double crossover event. From the difference in transformation efficiency between the vectors pPR16, pPR19F, and pPR2TN, it can be ...

The deployment of diverse sources of resistance in new cultivars underpins durable control of rust diseases. Aus27430 exhibited a moderate level of stripe rust resistance against Puccinia striiformis f. sp. tritici (Pst) pathotypes currently prevalent in Australia. Aus27430 was crossed with the susceptible parent Avocet S (AvS) and subsequent filial generations were raised. Monogenic segregation observed among Aus27430/AvS F3 families was confirmed through stripe rust screening of an F6 recombinant inbred line (RIL) population, and the resistance locus was temporarily named YrAW5. Selective genotyping using an Illumina iSelect 90K wheat SNP bead chip array located YrAW5 in chromosome 6A. Genetic mapping of the RIL population with linked 90K SNPs that were converted into PCR-based marker assays, as well as SSR markers previously mapped to chromosome 6A, confirmed the chromosomal assignment for YrAW5. Comparative analysis of other stripe rust resistance genes located in chromosome 6A led to the ...
Infestation pattern of P. indica in barley roots. (a) By 8 dai, hyphae excessively occupy rhizodermal and cortical cells of the differentiation zone. The elongation zone is less colonized, with occasional intercellular subepidermal hyphal structures. The root cap is heavily infested with hyphae. (b-e) After penetration (arrows) fungal hyphae colonize the subepidermal layer. (b) To better visualize the position of hyphae in the z axis, a confocal laser scanning image consisting of 30 frames of adjacent focal planes (z axis) was displayed as a maximum projection with the fluorescent signal of the wheat germ agglutinin-stained fungal hyphae displayed in red for the upper (abaxial) 15 frames and in green for the lower (adaxial, subepidermal) 15 frames. (c and d) For visualization of plant cell walls, two close-up bright-field images of two different focal planes are superimposed with the respective frames of the fluorescence images. Intercellular hyphae start branching and proliferate within the ...
Additionally, a blast analysis of the deduced amino acid sequence of the astaxanthin synthase enzyme, the product of the crtS gene, shows a high level of similarity with cytochrome P450 hydroxylase. In other organisms that synthesize astaxanthin, such as the microalgae H. pluvialis and the bacteria Agrobacterium auriantiacum (Misawa et al., 1995) or Paracoccus haeundaensis (Lee and Kim, 2006), the step from ß-carotene to astaxanthin using several ketocarotenoids as intermediates are controlled by two genes. The gene crtW that codes for the enzyme ß-carotene ketolase catalyzes the introduction of the keto groups, while the gene crtZ that codes for the enzyme ß-carotene hydroxylase catalyzes the incorporation of the hydroxyl groups in positions C3 and C3. However, in X. dendrorhous, the step from ß-carotene to astaxanthin is controlled by a single gene, crtS, that codes for the enzyme astaxanthin synthase, which is a cytochrome P450 hydroxylase-type enzyme, subfamily 3A (Ojima et al., 2006), ...

However, the potential of RNAi in wheat to efficiently and durably control the devastating stripe rust fungus Puccinia striiformis f. sp. tritici (Pst), remained largely under explored, so far. To address this issue, we generated transgenic wheat lines expressing double-stranded RNA targeting PsFUZ7 transcripts of Pst. We analyzed expression of PsFUZ7 and related genes, and resistance traits of the transgenic wheat lines. We show that PsFUZ7 is an important pathogenicity factor which regulates infection and ...
Hypersensitive adult plant resistance genes Lr48 and Lr49 were named based on their genetic independence of the known adult plant resistance genes. This study was planned to determine genomic locations of these genes. Recombinant inbred line populations derived from crosses involving CSP44 and VL404, sources of Lr48 and Lr49, respectively, and the susceptible parent WL711, were used to determine the genomic locations of these genes. Bulked segregant analyses were performed using multiplex-ready PCR technology. Lr48 in genotype CSP44 was mapped on chromosome arm 2BS flanked by marker loci Xgwm429b (6.1 cM) and Xbarc7 (7.3 cM) distally and proximally, respectively. Leaf rust resistance gene Lr13, carried by the alternate parent WL711, was proximal to Lr48 and was flanked by Xksm58 (5.1 cM) and Xstm773-2 (8.7 cM). Lr49 was flanked by Xbarc163 (8.1 cM) and Xwmc349 (10.1 cM) on chromosome arm 4BL. The likely presence of the durable leaf rust resistance gene Lr34 in both CSP44 and VL404 was confirmed ...

Leaf rust resistance gene Lr21 is present in hard red spring wheat (Triticum aestivum) cultivars grown in Minnesota, North Dakota, South Dakota, Manitoba, and Saskatchewan. Isolates of Puccinia triticina, the causal organism of wheat leaf rust, with virulence to this gene have not been previously detected in annual virulence surveys in the United States. (2). In 2010, hard red spring wheat cvs. Faller, RB07 (1), and Glenn, all with Lr21, had 0 to 5% levels of leaf rust severity, which was higher than in previous years in research plots in North Dakota and Minnesota. Leaf rust collections from wheat cultivars and germplasm lines with Lr21 at three locations in Minnesota and North Dakota were increased on plants of the leaf rust susceptible wheat Thatcher and the Thatcher line with Lr21. Single uredinia from the collections were isolated and increased on seedlings of Thatcher. The single uredinial isolates were inoculated to 7- to 8-day-old seedling plants of the set of 19 differential lines that ...
The expression of wheat leaf rust resistance genes Lr34, LrT3, and Lr12 was studied in seedlings of cv. Thatcher and the near-isogenic Thatcher genotypes RL6058-Lr34, line 920-Lr34, line 922-LrT3, and RL6011-Lr12 inoculated at 8 and 13 days old. Several Mexican pathotypes of Puccinia recondita f. sp. tritici were used for inoculation. Incubation was carried out at four temperature regimes (three greenhouse and one growth chamber). Gene Lr34 conferred resistance to all pathotypes, although the seedling infection types (ITs) varied among tests and ranged from slightly chlorotic flecks to 3+. Low ITs were best recognized in the older first leaves, which indicated that leaf growth stage affected the expression of resistance. The IT was influenced by the genetic background, temperature, and other environmental factors (perhaps light). The pathotype-specific response of LrT3 could be seen only at lower temperatures, whereas Lr12 was ineffective to all pathotypes at all temperature regimes. Gene Lr34 ...
Yellow rust is a potential threat to an already fragile Afghan wheat production system. The year 2009 to 2010 saw extensive yellow rust incidence in Afghanistan mainly due to Yr27 virulence. The 2012 to 2013 crop seasons also had yellow rust incidence throughout the country. A set of 20 wheat seed chain varieties was grown at six agro climatically different locations in the country to proactively detect any shift in yellow rust virulence spectrum in the country. Yellow rust incidence on these varieties was scored under natural conditions during flowering to dough crop stages. Results revealed widespread susceptible reaction of at least four wheat varieties viz., Diama 96, PBW154, Ghori 96 and Herat 99. Four other wheat varieties viz., Muqawim 09, Koshan 09, Rana 96 and Gul 96 showed susceptible reaction at least at one location; however, a total of 12 other seed chain varieties were confirmed resistant to prevalent yellow rust races under natural conditions. Results warrant caution in advocating
Abstract. Accepted 6th January, 2019. Wheat is one of the important cereal crops of Ethiopia. It ranks third in land coverage and total production after tef and maize and in productivity after maize and sorghum. Hararghe highlands are also considered to be suitable for wheat cultivation in the country. However, the production of wheat in this region is threatened by the stem rust disease. This study was conducted with the following objectives: to determine distribution, incidence and severity of wheat stem rust Puccinia graminis f.sp. tritici in Hararghe highlands. Field surveys were carried out in eight districts of east and west Haraghe zones. A total of 200 fields were surveyed. Stem rust occurred in 80% and 74% of the fields surveyed in East and West Hararghe zones, respectively. Its incidence was 38.32% and 30.43% in East and West Hararghe areas, respectively. There was significance difference among the zones, districts and peasant associations (P, 0.05). The highest mean severity (35.36%) ...
Stripe rust (also known as yellow rust), caused by the pathogen Puccinia striiformis f. sp. tritici (Pst), is a common and serious fungal disease of wheat (Triticum aestivum L.) worldwide. To identify effective stripe rust resistance loci, a genome-wide association study was performed using 152 wheat landraces from the Yellow and Huai River Valleys in China based on Diversity Arrays Technology and simple sequence repeat markers. Phenotypic evaluation of the degree of resistance to stripe rust at the adult-plant stage under field conditions was carried out in five environments. In total, 19 accessions displayed stable, high degrees of resistance to stripe rust development when exposed to mixed races of Pst at the adult-plant stage in multi-environment field assessments. A marker-trait association analysis indicated that 51 loci were significantly associated with adult-plant resistance to stripe rust. These loci included 40 quantitative trait loci (QTL) regions for adult-plant resistance. Twenty ...
Sample extracts also were processed in PCR reaction mixtures with primer set Pme1:Pme2, specific for P. meibomiae (data not shown). No diagnostic 330 bp band was observed from any of the plant samples processed. Purified P. meibomiae DNA (80 ng in 4 l) was amplified in a positive control, and the diagnostic 330 bp band was observed. A faint band approximately 330 bp in size also was observed when P. pachyrhizi DNA (80 ng in 4 l) was used as a negative control. These results indicate that sample extracts should be processed with both primer sets, especially if a faint band is observed, because observation of a faint band produced with Ppa1:Ppa2 primers could indicate little P. pachyrhizi DNA in the sample or non-specific amplification of P. meibomiae DNA.. PCR product in DNA bands produced from amplification of soybean leaf extract was excised from the gel. DNA was extracted, purified (Qiaquick Gel Extraction kit, Qiagen Inc., Valencia, CA), and sent for sequencing to the DNA Sequencing Core ...
Isolates of Puccinia graminis f. sp. tritici belonging to the Ug99 race group are virulent to a broad spectrum of resistance genes, rendering most of the worlds wheat germplasm susceptible to stem rust (3). Following the initial detection of Ug99 (TTKSK, North American [NA] race notation) in Uganda, virulence to the widely used Sr31 resistance gene has been reported from

A small cysteine-rich protein from the Asian soybean rust fungus, Phakopsora pachyrhizi, suppresses plant immunity. PLoS Pathogens. 12(9): e1005827. doi:10.1371/journal.ppat.1005827. Interpretive Summary: The Asian soybean rust fungus, Phakopsora pachyrhizi, is an obligate pathogen capable of causing explosive disease epidemics that drastically reduce the yield of soybean. Currently, the mechanisms by which P. pachyrhizi and other related fungi cause disease are poorly understood. The genome sequences and other data obtained from these fungi indicate that a variety of small proteins play essential roles that enable them to cause disease. These proteins, called effectors, are released by the pathogen and interfere with a plants ability to fight the disease. Here, we identify an effector protein produced by P. pachyrhizi and demonstrate that it is capable of ...
In Kansas, wheat (Triticum aestivum L.) is severely affected by the biotrophic fungus Puccinia triticina (leaf rust). Although resistant varieties have been developed, the fungus tends to overcome new sources resistance very quickly. Plants have evolved a single gene (R genes) defense network that can recognize specific pathogen effectors (Avr), in a gene-for-gene manor. In rusts, effectors are secreted proteins responsible for inducing the uptake of nutrients and inhibit host defense responses. Identification of secreted proteins during the infection may help to understand the mode of infection of P. triticina. Little is known about molecular interactions in the pathosystem wheat-leaf rust and no Avr genes from cereal rusts have been cloned. In order to understand pathogenicity in leaf rust and generate new alternatives for disease control, the goal of this research is identify P. triticina secreted proteins from a collection of expressed genes during the infection, and to characterize putative ...

The Tremella Fuciformis Sorocarp Extract is derived from the tremella fuciformis which is a species of fungus belonging to the Tremella Genus also known as the Silver Ear mushroom from China. The fungus is comprised of 5 sugar units and contains a polymer molecular structure. The fungi are often cultivated and used for cuisine and medicinal purposes. In the past, Yang Guifei a beauty legend of China was said to have used the mushroom to soften and smooth the skin.. In skin care products, the ingredient has been found to help the skin retain moisture while preventing the breakdown of micro-blood vessels. As a result, Tremella Fuciformis Sorocarp Extract reduces the appearance of lines and wrinkles.. The Tremella Fuciformis Sorocarp is an acidic hetero-polysacchaaride that has been used since ancient times to beautify the skin. In addition to its moisturizing characteristics, the extract has been found to provide antioxidant activity. Research indicates that the Tremella Fuciformis has shown ...
Wheat yield and quality is influenced by many abiotic and biotic environmental factors. Pre- harvest sprouting (PHS) occurs when physiologically matured spikes are exposed to wet field conditions before harvest, which results in seed germination and causes significant losses in yield and end-use quality. Wheat stripe rust is one of the most important biotic factors reducing grain yield and quality. To investigate the genetic basis of the resistance to PHS and stripe rust in hard white winter wheat cultivars Danby and Tiger and develop molecular markers for marker- assisted breeding, a double haploid (DH) population, derived from those two cultivars, was genotyped with simple sequence repeats (SSR) markers and simple nucleotide polymorphism (SNP) markers. This DH population was assessed for resistance to PHS and stripe rust in both greenhouse and field experiments. For PHS, one major resistant quantitative trait locus (QTL) was consistently detected on the short arm of chromosome 3A in all three ...
The fungi that cause rust diseases are fascinating; many require more than one host to survive, and all produce, in succession, two or more different types of spores during the growing season. Rust fungi are related to the mushrooms you purchase in the supermarket, but the spores produced by these organisms are found in "rusty" (yellow to orange to brown) pustules on leaves, stems, needles, and fruit. Rust fungi are biotrophs: they do not grow in absence of a living host, and they tend to have a narrow host range.. Some rust fungi have a unique life history; those fungi that need more than one host plant to complete their life cycle (called alternate hosts) are heteroecious. Examples of heteroecious rust diseases include the Gymnosporangium rusts (for example, cedar-apple rust and quince rust), ash rust, and fuchsia rust. Alternatively, other rust fungi do not require more than one host plant to survive; these rust fungi are autoecious and include hollyhock rust, pine-pine gall rust, and ...

To identify new sources of resistance to Pst that were effective in different environments of the western United States, we performed field evaluations in three locations with very different ecological conditions. Despite these differences, we observed high correlations among IT and SEV values obtained from the different environments (Table 2). These high correlations suggest that there might be similar Pst populations across the western United States. This hypothesis is supported by the known paths of spore dispersal by wind (Chen 2005) and by periodic spore surveys across this region. In the last published Pst race survey from 2010 (Wan and Chen 2014), 20% of the races detected in California and Washington were shared between the two states (PSTv-8, PSTv-14, PSTv-36, PSTv-37, PSTv-40, and PSTv-41), providing further support to the previous hypothesis. The high correlations among environments were also reflected in high heritability for IT and SEV values (Table 1), which were favorable for the ...
Emerging and re-emerging pathogens imperil public health and global food security. Responding to these threats requires improved surveillance and diagnostic systems. Despite their potential, genomic tools have not been readily applied to emerging or re-emerging plant pathogens such as the wheat yellow (stripe) rust pathogen Puccinia striiformis f. sp. tritici (PST). This is due largely to the obligate parasitic nature of PST, as culturing PST isolates for DNA extraction remains slow and tedious. To counteract the limitations associated with culturing PST, we developed and applied a field pathogenomics approach by transcriptome sequencing infected wheat leaves collected from the field in 2013. This enabled us to rapidly gain insights into this emerging pathogen population. We found that the PST population across the United Kingdom (UK) underwent a major shift in recent years. Population genetic structure analyses revealed four distinct lineages that correlated to the phenotypic groups determined through

Phellinus linteus (Japanese "meshimakobu", Chinese "song gen", Korean "sanghwang", English "Meshima", American English "black hoof mushroom") is a medicinal mushroom used in Japan, Korea and China for centuries to prevent ailments as diverse as gastroenteric dysfunction, diarrhea, haemorrhage and cancers. It is shaped like a hoof, has a bitter taste, and in the wild grows on mulberry trees. The stems color ranges from dark brown to black. In Korean traditional medicine, the mushroom is consumed in the form of hot tea. Early research has suggested that Phellinus linteus has anti-breast cancer activity. A paper published by Harvard Medical School reported that Phellinus linteus is a promising anti-cancer agent, but that more research is required to understand the mechanisms behind its anti-cancer activity. Nine compounds were isolated from the active ethylacetate fraction of the fruiting body and identified as protocatechuic acid, protocatechualdehyde, caffeic acid, ellagic acid, hispidin, ...

Piriformospora indica is known as a fungus that can easily colonize a wide range of plants and enhance hosts growth and tolerance to abiotic stresses, including salinity. The mechanistic basis behind this phenomenon remains poorly understood. This work was aimed to fill in this gap and reveal mechanisms enhancing salinity tolerance in maize roots colonised by P. indica. A range of agronomic and physiological characteristics were compared between inoculated and non-inoculated maize plants under 0/100/200 mM NaCl conditions. The impact of P. indica inoculation or roots cytosolic K+ retention ability were also assessed using micro-electrode ion flux estimation technique. The results showed that inoculated plants had higher biomass, higher stomatal conductance, lower K+ efflux from roots and higher potassium content in shoots than non-inoculated plants under salt stress. Collectively, the results indicated that the beneficial effects of inoculation on plant performance under saline conditions were ...
We demonstrated and characterized the production of pro Vitamin A, beta-Carotene, in Saccharomyces cerevisiae, by importing three carotegenic genes from Xanthophyllomyces dendrorhous, namely carotene desaturase, GGPP synthase, phytoene synthase. The quantification was done via HPLC analysis and spectrophotometric assays over time. We also ran a comparative study of our yeast strains efficiency in dough versus in lab conditions using a novel substrate, dough media plates. We observed production of significant amounts of beta-carotene from this strain. We have engineered a strain of Saccharomyces cerevisiae to express L-ascorbic acid, or Vitamin C, for use in the baking of bread and brewing of beer. We codon-optimized three genes from the Vitamin C pathway of Arabidopsis thaliana and made them BioBrick compatible. These were then constructed de novo and assembled into expression cassettes. We are currently in the process of characterizing the Vitamin C production via HPLC and photospectrometric ...

Stripe rust and leaf rust, caused by Puccinia striiformis Westend. f. sp. tritici Erikss. and P. triticina, respectively, are devastating fungal diseases of common wheat ( Triticum aestivumL.)....
Stem rust is one of the most devastating diseases affecting wheat worldwide. In North America the last epidemics were recorded in 1955, since then stem rust has been under control by the use of resistant cultivars and eradication of alternate hosts. Resistant cultivars have always been effective control of this disease worldwide. But in 1999 a new race of Puccinia graminis f. sp. tritici, the causative agent of stem rust, was detected in Uganda that was virulent against the traditional wheat resistance genes, Sr31 and Sr38 (1). This race was denominated TTKS, or alternatively, Ug99. In 2003 race Ug99 was found in Kenya and in 2007 in Yemen (1-3). This virulent race could soon migrate to the Middle East and Central Asia and can attack many of the current cultivars in use worldwide (4, 5). Due to the widespread susceptibility to Ug99 and the potential perspectives of new widespread stem rust epidemics, the Global Rust Initiative (www.globalrust.org) set as one of its top priorities the monitoring ...

In plants, disease resistance mediated by the gene-for-gene mechanism involves the recognition of specific effector molecules produced by the pathogen either directly or indirectly by the resistance-gene products. This recognition triggers a series of signals, thereby serving as a molecular switch in regulating defense mechanisms by the plants. To understand the mechanism of action of the barley stem rust resistance gene Rpg1, we investigated the fate of the RPG1 protein in response to infection with the stem rust fungus, Puccinia graminis f. sp. tritici. The investigations revealed that RPG1 disappears to undetectable limits only in the infected tissues in response to avirulent, but not virulent pathotypes. The RPG1 protein disappearance is rapid and appears to be due to specific protein degradation via the proteasome-mediated pathway as indicated by inhibition with the proteasomal inhibitor MG132, but not by other protease inhibitors ...
Dry rot genome offers lessons for biofuel pretreatment processes. Feared by realtors and homeowners alike, dry rot due to the fungus Serpula lacrymans causes millions of dollars worth of damage to homes and buildings around the world. This brown rot fungus capacity to break down the cellulose in wood led to its selection for sequencing by the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) in 2007, with the goal of identifying the enzymes involved in the degradation process and using the information to improve cellulosic biofuels production.. As reported online July 14 in Science Express, an international team of scientists including DOE JGI researchers compared the genome of Serpula lacrymans, the second brown rot fungus to have its genome sequenced, against 10 other published fungal genomes. The DOE JGI sequenced seven of these genomes among them Postia placenta, the first brown rot fungus sequenced. The analysis not only allowed researchers to understand the chemical reactions ...

There are now numerous reports of stripe rust (Puccinia striiformis) in Oklahoma, Texas and Kansas. With the current cool and rainy weather conditions, the development of stripe rust in Colorado wheat could be possible.
English name - Snow Fungus Japanese name - Shirokikurage / Hakumokuji Chinese name - Bai Mu Er / Yin Er As well as being a popular culinary mushroom in oriental cuisine, Tremella Fuciformis has a long history of medicinal use and like other jelly fungi, Tremella Fuciformis is rich in bio-active polysaccharides. In china, Snow Fungus is a popular an anti-aging supplement with over 40 Chinese patents citing it during the 1990s alone. Its anti-aging effects are due to Snow Fungus allowing the skin to retain more water and helps prevent senile degeneration (the breaking down over time) of micro blood vessels within the skin and keep blood flowing through the skin optimally. Imagine a moisturising lotion, but instead of chemicals being spread on to the skin to hold in moisture, the Snow Fungus helps the skin moisturise and regenerate internally and naturally. Much research in to this medicinal mushroom has focussed on its ability to support the systems of people undergoing chemotherapy. It shows broad

PHP-2012-0227-01-R. Interpretive Summary: Soybean rust is an important disease of soybean caused by a fungus first discovered in the United States in 2004. The incident of disease in the field often has been observed to increase in fall months at a time when plants are approaching full maturity. This increase in disease has caused some researchers to speculate that as plants begin to flower they become more susceptible to infection by the pathogen. To determine if the speculation was correct, we undertook a study of plant and leaf age to susceptibility to soybean rust. Our results under controlled conditions in growth chambers and greenhouse indicate that the increase is not due to changes in the plant but more likely to changes in the environment from one that is less favorable to one that is more favorable for ...
The Swiss winter bread wheat cultivar "Forno" has been showing near immune levels of leaf rust resistance since its release in 1986. At least six different loci contribute to this phenotype (1). The largest fraction of the phenotipic variation (33-43%) is explained by Lr34. Regretfully, this gene is associated with leaf tip necrosis, an undesirable trait in Western Europe breeding programs. The same authors determined that the second largest source of variation (28-32%) was due to a loci on chromosome arm 1BS, named QLr.sfr-1BS (1). ...
