The Dasypyrum villosum gene bank collection, comprising 32 accessions, was characterized morphologically and genetically for resistance to leaf diseases quality parameters of seeds with specific accent protein polymorphism starch composition. collected material represented nearly the whole distribution area in Mediterranean. For SSR analysis, a set 40 markers wheat selected. A matrix distances ...
Recent disease outbreaks caused by (re-)emerging plant pathogens have been associated with expansions in pathogen geographic distribution and increased virulence. For example, in the past two decades' wheat yellow (stripe) rust, Puccinia striiformis f. sp. tritici, has seen the emergence of new races that are adapted to warmer temperatures, have expanded virulence profiles, and are more aggress...
Problems associated with annual grain agriculture, such as soil erosion and water and air pollution, indicate that reliance on annual grain production is a fundamental problem of current agricultural practice (23). Annual plant roots are less efficient micromanagers of water, soil, and soil nutrients than their perennial counterparts, resulting in nutrient and pesticide contamination of water s...
Rust fungi are obligate parasites and cannot be routinely cultured to obtain sufficient biomass for DNA extractions. Multiple displacement amplification (MDA) was demonstrated in this study for whole genome amplification from single spores of the rust fungus, Puccinia striiformis. The genomic DNA coverage and fidelity of this method was evaluated by PCR amplification and sequencing of two genet...
Previously we extended the utility of mapping-by-sequencing by combining it with sequence capture and mapping sequence data to pseudo-chromosomes that were organized using wheat-Brachypodium synteny. This, with a bespoke haplotyping algorithm, enabled us to map the flowering time locus in the diploid wheat Triticum monococcum L. identifying a set of deleted genes (Gardiner et al., 2014). Here, ...
in order to study genetic diversity of aegilops tauschii populations, 188 populations of national plant gene bank collection of iran were evaluated for morphological traits according to ipgri descriptors in research station of national plant gene bank. moreover, 100 out of 188 populations were evaluated in research station of seed and plant improvement institute for resistance to yellow rust, p...
