Wheat (Triticum spp.) is one of the founder crops that likely drove the Neolithic transition to sedentary agrarian societies in the Fertile Crescent more than 10,000 years ago. Identifying genetic modifications underlying wheat's domestication requires knowledge about the genome of its allo-tetraploid progenitor, wild emmer (T. turgidum ssp. dicoccoides). We report a 10.1-gigabase assembly of t...
To elucidate the genetic mechanism of flowering in wheat, we performed expression, mutant and transgenic studies of flowering-time genes. A diurnal expression analysis revealed that a flowering activator VRN1, an APETALA1/FRUITFULL homolog in wheat, was expressed in a rhythmic manner in leaves under both long-day (LD) and short-day (SD) conditions. Under LD conditions, the upregulation of VRN1 ...

the applicability of rapds, aflps, and ssrs to examine genetic relationships in 36 populations of triticum boeoticum from west of iran was investigated. a total of 224 (135 polymorphic), 979 (429 polymorphic) and 246 (145 polymorphic) bands/alleles were detected using 14 rapd primers, 17 aflp primer combinations and 17 well distributed, mapped ssr markers, respectively. the polymorphic informat...
this recent study documents the phenolic constituents of the triticum l. species in iran using thinlayer chromatography. species studied are related to 55 wild and cultivated accessions of four diploid andfour tetraploid species, namely triticum boeoticum subsp. boeoticum boiss., t. boeoticum subsp. thaoudarreut. ex boiss., t. monococcum l., t. urartu tum. ex gand., t. turgidum l., t. dicoccoid...
With respect to the maternally inherited large subunit of fraction I protein, Chen et al. (1) found that Triticum boeoticum and T. urartu had identical polypeptide patterns, and Aegilops speltoides had a different one identical with that of the tetraploid wheats. From this evidence they inferred that Ae. speltoides. but neither T. boeoticum nor T. urartu, could have been the maternal parent of ...
Genetic resources of crop plants are essential for crop breeding. They are conserved in gene banks in form of a large numbers of accessions. These accessions harbor allelic variants of agronomically important genes and molecular tools allow a rapid assessment of this allelic diversity. Here, we have screened a collection of 1005 wheat gene bank accessions for powdery mildew resistance and a mol...
in order to study genetic diversity in 178 accessions of lentil (lens culinaris medik) originated from warm climate regions of iran, this experiment was conducted in 2009 at research farm of the national plant gene bank of iran in karaj. experimental design was an augmented experiment with six blocks and each block containes 30 accessions. accessions were compared with promising lines including...
synthetic plants as well as wild crop species are valuable genetic resourses. to determine the genetic variation in triticale, tritipyrum as well as wheat lines, genomic dna of this amphiploid including thinopyrum bessarabicum and durum wheat were amplified using 32 random and 22 semi random primers. primers that could produce clear, polymorphic and repetitive bands are used for determination o...
Abstract Determination of genetic diversity level is important in clarifying genetic relationships, characterizing germplasm and the registration of new cultivars. In this study, genetic variation among 56 accessions (G1~G56) of Citrus including several undefined local or native genotypes and some known varieties in Jiroft, Kerman province, Iran was investigated using SSR markers. In total, 12 ...
