Elymus L. is the largest genus in the tribe Triticeae Dumort., encompassing approximately 150 polyploid perennial species widely distributed in the temperate regions of the world. It is considered to be an important gene pool for improving cereal crops. However, a shortage of molecular marker limits the efficiency and accuracy of genetic breeding for Elymus species. High-throughput transcriptome sequencing data is essential for gene discovery and molecular marker development. We obtained the transcriptome dataset of E. sibiricus, the type species of the genus Elymus, and identified a total of 8871 putative EST-SSRs from 6685 unigenes. Trinucleotides were the dominant repeat motif (4760, 53.66%), followed by dinucleotides (1993, 22.47%) and mononucleotides (1876, 21.15%). The most dominant trinucleotide repeat motif was CCG/CGG (1119, 23.5%). Sequencing of PCR products showed that the sequenced alleles from different Elymus species were homologous to the original SSR locus from which the primer was
Elymus (Poaceae) is a large genus of polyploid species in the wheat tribe Triticeae. It is polyphyletic, exhibiting many distinct allopolyploid genome combinations, and its history might be further complicated by introgression and lineage sorting. We focus on a subset of Elymus species with a tetraploid genome complement derived from Pseudoroegneria (genome St) and Hordeum (H). We confirm the species allopolyploidy, identify possible genome donors, and pinpoint instances of apparent introgression or incomplete lineage sorting. We sequenced portions of three unlinked nuclear genes-phosphoenolpyruvate carboxylase, β-amylase, and granule-bound starch synthase I-from 27 individuals, representing 14 Eurasian and North American StStHH Elymus species. Elymus sequences were combined with existing data from monogenomic representatives of the tribe, and gene trees were estimated separately for each data set using maximum likelihood. Trees were examined for evidence of allopolyploidy and additional ...
The seedling were treated with different temperature(10℃、5℃、0℃) and time(1d、3d、5d) to study effects of low temperature stress on physiological process of Poa pratensis L,K.thoroldiana,Elymus nutans.The results indicated that,with the temperature declining and stress time prolonging,the content of chlorophyll declined,the electrolyte leakage and Soluble sugar content in Poa pratensis L.K.thoroldiana,and Elymus nutans increased.Under 0℃ for 5 days,the content of chlorophyll of Elymus mutans declined significantly by 48.5% of chlorophlla and 55.1% of chlorophyll b. The increasing scope of the electrolyte leakage of Elymus nutans was most, about 157.4%,but of Poa pratensis L.was least,about 71.9%;Soluble sugar content of Poa pratensis was dramatically increased.So the Poa pra-tensis L.was suited to low-temperature and had higher ability of resisting cold,the order of chilling resistance for those kinds grasses was Poa pratensis L.,Kengyilia throldiana and Elymus nutans.

The general line between animals that should be protected from suffering (mammals) and animals that do not (mosquitoes) generally is connected the level of conscience and their desire to live. Gaea is sometimes interpreted as affording the whole earth a sense of being and a sort of collective conscience. Genes within a genome of a species of animal or plant (or other life-form) has a form of intelligence where genes that result in increased survival and ultimately the successful reproduction of individuals who have such a gene being active, are selectively increased in percentage among the population of that genome. Because of this, the genome of the population can be seen as a being that strives to survive and adapts accordingly. I feel a moral urge to respect this desire to live among genomes of different species. This respect for genomes comes into conflict at times of respect for the desire to live among individuals within that genomes species. I will use an extreme example to illustrate ...

Robustness to sand dune impact is one of the key requirements for Jaguar Land Rover products. Historically off road vehicles were built on a ladder sub frame; and the steel cross beam at the front provided robust protection for the cooling pack. With the move to monocoque construction, the cooling pack became vulnerable to low speed grounding damage. Unfortunately this vulnerability is not confirmed until later in the program when fully representative vehicles are available, which results in late engineering changes that are expensive, time consuming and stressful. Like all late changes it is rarely optimised for cost and weight. With no historic literature or procedure available, the challenge was to model the physics of sand media and also solve the complex multi-physics problem of impact of the whole vehicle with the sand dune. This paper discusses various challenges faced while developing a state-of-the-art modelling method for sand media and a full vehicle impact with the sand dune. Our ...

The Licensee will also need to demonstrate that there will not be a disproportionate increase in risk from an appropriate range of events which are more severe than the design basis event. This is generally known as the cliff edge effect. The way in which this principle is satisfied may depend on the nature of the hazard being addressed. For some hazards a point will be reached where there is a step change in the effect on the installation. In the case of external flooding, for example, the site defences become overtopped. In such cases, it needs to be shown that there is a reasonable margin between the design basis and the point at which this step change would occur. For other hazards, such as seismicity, the forces acting on the installation will continue to increase progressively with increasing size or proximity of the event. A demonstration is needed that there will not be a step change in the response of the installation to the hazard, in terms of the likelihood of a release of ...
Four leaf preparation techniques (air drying, tetramethylsilane air drying, critical point drying, and freeze substitution) used in scanning electron microscopy (SEM) were evaluated with respect to the degree of cellular distortion they produce in stomatal guard cells of leaves of Dactylis glomerata and Elymus canadensis. Surface morphological distortion and cuticle disruption in the air-dried and tetramethylsilane air-dried leaves, and cuticle disruption within the critical point-dried tissue made it difficult to obtain measurements.The freeze-substituted tissue experienced little cuticle disturbance, and the cellular morphology appeared normal. The length of the guard cells did not significantly differ between the air-dried, tetramethylsilane air-dried, critical point-dried, or freeze-substituted samples. Widths did significantly vary, with the freeze-substituted tissue having lower values than tissues treated with the other treatments. Freeze substitution methodology produced SEM images that appear
During 1986 and 1987, a weed survey of 187 New Brunswick cereal fields was conducted. A total of 76 species were identified, of which 40 were considered agronomically important. About 50% of the species were perennial. Hemp-nettle (Galeopsis tetrahit), quack grass (Agropyron repens [Elymus repens]), sheep sorrel (Rumex acetosella), ox-eye daisy (Chrysanthemum leucanthemum [Leucanthemum vulgare]), corn spury (Spergula arvensis) and chickweed (Stellaria media) had the highest relative abundance values. Quack grass and hemp-nettle had the highest densities at 8.0 and 7.1 plants m-2, respectively. The highest weed density (103 plants m-2) was found in oats (Avena sativa) grown after a forage crop. The lowest density (24 plants m-2) was found in wheat (Triticum aestivum) grown after potatoes (Solanum tuberosum). Most of the abundant species were tolerant to MCPA, the most commonly used herbicide. It was concluded that farmers could make major improvements in cereal weed control by choosing a ...

To investigate the potential use of n-alkanes (alkanes), long-chain alcohols (alcohols) and long-chain fatty acids (acids) for estimating the diet composition of sheep, in a feeding trial. A total of 18 sheep were assigned randomly to three different diets (diet A, diet B and diet C) containing up to eight herbage species (Leymus chinensis, Leymus dasystachys, Elymus sibiricum, Chenopodium album, Puccinellia chinampoensis, Medicago sativa, Saussurea sinuata and Bromus inermis). Faecal recoveries of alkanes, alcohols and acids were determined, and diet compositions were estimated using different combinations of alkanes, alcohols and acids. The faecal concentrations of individual alkanes, alcohols and acids were corrected using the mean recovery of the dietary treatment that the respective animal belonged to (diet recovery), or the mean recovery across all dietary treatments (general recovery). In general, diets did not affect the faecal recovery values for alkanes, alcohols and acids, and no difference
Main conclusion The most conspicuous difference among chromosomes and genomes in Arachis species, the patternsof heterochromatin, was mainly modeled by differential amplification of different members of one superfamily ofsatellite DNAs.Divergence in repetitive DNA is a primary driving force for genome and chromosome evolution. Section Arachis is karyotypicallydiverse and has six different genomes. Arachis glandulifera (D genome) has the most asymmetric karyotype andthe highest reproductive isolation compared to the well-known A and B genome species. These features make A. glanduliferaan interesting model species for studying the main repetitive components that accompanied the genome and chromosomediversification in the section. Here, we performed a genome-wide analysis of repetitive sequences in A. glandulifera andinvestigated the chromosome distribution of the identified satellite DNA sequences (satDNAs). LTR retroelements, mainlythe Ty3-gypsy families ?Fidel/Feral? and ?Pipoka/Pipa?, were the ...
The goal is to establish the common or crystalline ice plant (Mesembryanthemum crystallinum L.) as a DOE Plant Flagship Genome species. The ice plant was the first reported halophytic, facultative crassulacean acid metabolism (CAM) species, meaning that the plant can be induced to switch from C3 photosynthesis to CAM following water-deficit or salinity stress treatment. CAM is an alternative mode of photosynthetic carbon uptake and CO2 concentrating mechanism that is present in approximately 6.5% of vascular plant species. CAM improves the water-use efficiency (WUE) in these plant species by temporally shifting all or part of net atmospheric CO2 fixation to the nighttime when evapotranspirational water losses are reduced relative to the daytime..

This paper presents the application of three publicly available biota dose assessment models (the ERICA Tool, R&D128/SP1a and RESRAD-BIOTA) to an assessment of the Drigg coastal sand dunes. Using measured 90Sr, 99Tc, 137Cs, 238Pu, 239+240Pu and 241Am activity concentrations in sand dune soil, activity concentration and dose rate predictions are made for a range of organisms including amphibians, birds, invertebrates, mammals, reptiles, plants and fungi. Predicted biota activity concentrations are compared to measured data where available. The main source of variability in the model predictions is the transfer parameters used and it is concluded that developing the available transfer databases should be a focus of future research effort. The value of taking an informed user approach to investigate the way in which models may be expected to be applied in practice is highlighted and a strategy for the future development of intercomparison exercises is presented..

Brassica species belong to the Brassicaceae family, which contains about 3700 species from 338 genera, including the widely studied model plant Arabidopsis thaliana. Brassica species include both vegetable and oilseed crops that contribute about 10% of the worlds vegetable production and about 12% of worlds edible vegetable oil production [1, 2]. The diploid genomes of the six widely cultivated Brassica species are described by the famous "Us triangle" (genome A, B, C, AB, BC and AC, corresponding to B. rapa, B. oleracea, B. nigra, B. juncea, B. napus, and B. carinata, respectively [3]. The A genome species, B. rapa, is a major vegetable and also an oil crop in Asia and Europe. Because of their importance as crops and as models to study complex genome hybridization and polyploidization [4, 5], genetic and genomic research on Brassicas has intensified over recent years, generating ever increasing sets of data, such as Brassica genome sequences, genetic markers, expressed sequence tags (ESTs) ...

Contact: John Horning 505-988-9126 x 1153 Santa Fe, NM-The U.S. Fish and Wildlife Service (Service) today proposed to list the sand dune lizard (Sceloporus arenicolus) as an endangered species under the Endangered Species Act (ESA). The proposal comes 9 years after the Service made it a candidate for ESA protection; 13 years after scientists warned that it may be too late to save the lizard from extinction; and 28 years after the Service first recognized the species may be imperiled.. "The sand dune lizard badly needs federal protection under the Endangered Species Act. While we welcome this proposal, it is more than a decade overdue, and the species has only declined during that time. The lizard faces an urgent situation," stated John Horning of WildEarth Guardians.. The Service placed the lizard on the ESA candidate list in October 2001, but the species has since been caught up in the general lack of progress in the endangered species listing program nationwide. Interior Secretary Salazar has ...
