Regulation of VRN-1 vernalization genes in normal and transgenic polyploid wheat.
Vernalization, the requirement of a long exposure to low temperatures to accelerate flowering, is an essential adaptation of plants to cold winters. The vernalization gene VRN-1 plays an important role in this process in diploid (Triticum monococcum) and polyploid wheat (Triticum aestivum). We have recently shown that the diploid wheat VRN-A(m)1 gene was similar to the Arabidopsis (Arabidopsis ...
متن کاملGenetic and Molecular Characterization of Vernalization Genes Vrn-A1, Vrn-B1, and Vrn-D1 in Spring Wheat Germplasm from the Pacific Northwest Region of the U.S.A
The objective of this study was to determine the Vrn-1 allelic composition of spring wheat germplasm from the Pacific Northwest region of the USA. Individual plants from 56 spring wheat lines were crossed to near-isogenic tester lines carrying the dominant allele VrnA1, Vrn-B1 or Vrn-D1. F2 progeny were evaluated for growth habit in the field and Vrn-1 allelic composition was determined through...
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-...
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...
