A Novel Retrotransposon Inserted in the Dominant Vrn-B1 Allele Confers Spring Growth Habit in Tetraploid Wheat (Triticum turgidum L.)
Vernalization genes determine winter/spring growth habit in temperate cereals and play important roles in plant development and environmental adaptation. In wheat (Triticum L. sp.), it was previously shown that allelic variation in the vernalization gene VRN1 was due to deletions or insertions either in the promoter or in the first intron. Here, we report a novel Vrn-B1 allele that has a retrot...
متن کاملGenome size variation in diploid and tetraploid wild wheats
BACKGROUND AND AIMS Intra- and interspecific variations of C-values and the relationship between habitat factors and genome size were studied in natural populations of diploid and tetraploid wild wheats. METHODOLOGY The 1C nuclear DNA content of 376 individual plants representing 41 populations of diploid and tetraploid wild wheats was determined by flow cytometry (FCM) and correlated with ge...
متن کاملCorrelation of Vernalization Loci VRN-H1 and VRN-H2 and Growth Habit in Barley Germplasm
Vernalization requirement is a key component in determining the overall fitness of developmental patterns of barley to its environment. We have used previously reported markers and spring-sown growth habit nursery to characterize the genotypes of barley germplasm in an applied barley breeding ground to establish a baseline of information required to understand the relationship between adaptatio...
متن کاملProteome analysis of diploid, tetraploid and hexaploid wheat: towards understanding genome interaction in protein expression.
Hexaploid wheat (Triticum aestivum L.) is derived from a complex hybridization procedure involving three diploid species carrying the A, B and D genomes. The proteome patterns of diploid, tetraploid and hexaploid wheat were analyzed to explore the genome interaction in protein expression. At least two species from each of the diploid and tetraploid were used to compare their proteome maps with ...
متن کاملAllelic Variation of VRN-1 Locus in Iranian Wheat Landraces
Wheat is a crop with spring and winter types and wide adaptability to different climate conditions. The wide adaptability of wheat is mainly controlled by three groups of genetic factors and among them vernalization (VRN) genes play pivotal role in determining spring and winter types. In this study, 395 Iranian wheat landraces were characterized with specific primer pairs designed based on VRN-...
