A general method based on variation in repeated nucleotide sequences was developed for the identification of diploid species most closely related to a specific genome of a polyploid species. The utility of this method was demonstrated by showing that Triticum speltoides is the most closely related extant species to both the B and G genomes of tetraploid wheats.

the genus aegilops is one of the wheat relatives which comprise the main part of its gene pool.the identification of the aegilops species is difficult due to their vast morphological similarities and geneflow among different species of aegilops and cultivated wheat. some morphological characters are used todistinguish different species in aegilops. in this study, we evaluate all these character...

The preferred livelihood assets for meat and nutritious milk in thousands villages of Kurdistan rejoin/Iraq are sheep goats. They generally rely on free roaming rangeland during the growing seasons. In order to maintain their livestock scarcity forages at winter seasons, leaves twigs (Quercus aegilops, Q. infectoria libani) harvested dried as (dry leaf faggots) autumn season use major substitut...

Plant species effects on ecosystem processes are mediated by traits such as litter quality and exudation. These same traits also influence the activity and distribution of animals that play key roles in regulating ecosystem dynamics. We planted monocultures of eight plant species commonly found in California grasslands to investigate the relative importance of plant species direct effects on ni...

M A N Y characters which would-be desirable in cultivated crops are known to exist in related species and genera. The most striking examples of such characters are the resistances to various diseases. Where hybridization can be achieved between the pertinent genera, attempts have been made to transfer genes for these desired characters into the genome of the cultivated species. Partially for th...

Aegilops tauschii Coss. is the D-genome donor to hexaploid bread wheat (Triticum aestivum) and is the most promising wild species as a genetic resource for wheat breeding. To study the population structure and diversity of 81 Ae. tauschii accessions collected from various regions of its geographical distribution, the genomic representation of these lines were used to develop a diversity array t...

the high molecular weight glutenin subunit (hmw-gs) compositions of 19 diploid wild wheat (t.boeoticum) and 36 diploid wild wheat (a.tauschii) were determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis (sds-page). all of t. boeoticum were characterized for their hmw-gs, showed 2* in their glu-a1 locus. in the study of aegilops tauschii that were collected from iran and 7 neig...

in this study, 120 aegilops crassa (mmdd genome) accessions from iran were evaluated for high molecular weight proteins. based on sds-page analysis, 17 bands were selected and mass spectrometry was used for protein identification. among 17 bands selected for maldi-tof-tof-ms analyzing, only 4 bands were identified as high molecular weight glutenin subunit similar to aegilops ventricosa and trit...
