Allelic 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 کاملIdentification of a large deletion in the first intron of the Vrn-D1 locus, associated with loss of vernalization requirement in wild wheat progenitor Aegilops tauschii Coss.
Vernalization promotes flowering in winter wheat cultivars, whereas spring wheat cultivars are able to transition from vegetative to reproductive phase without vernalization. The wheat vernalization requirement is mainly controlled by the major locus Vrn-1, an APETALA1/FRUITFULL MADS-box gene homolog. To study natural variation of the vernalization requirement in a wild progenitor of common whe...
متن کاملA 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 کاملAllelic variation at the vernalization and photoperiod sensitivity loci in Chinese winter wheat cultivars (Triticum aestivum L.)
A total of 205 wheat cultivars from the Yellow and Huai valley of China were used to identify allelic variations of vernalization and photoperiod response genes, as well as the copy number variations (CNVs) of Ppd-B1 and Vrn-A1 genes. A novel Vrn-D1 allele with 174-bp insertion in the promoter region of the recessive allele vrn-D1 was discovered in three Chinese wheat cultivars and designated a...
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...
