Molecular characterization of vernalization loci VRN1 in wild and cultivated wheats [PDF]
BMC Plant Biology, 2010 Background Variability of the VRN1 promoter region of the unique collection of spring polyploid and wild diploid wheat species together with diploid goatgrasses (donor of B and D genomes of polyploid wheats) were investigated. Accessions of wild diploid (

VRN1 genes variability in tetraploid wheat species with a spring growth habit [PDF]
BMC Plant Biology, 2016 Background Vernalization genes VRN1 play a major role in the transition from vegetative to reproductive growth in wheat. In di-, tetra- and hexaploid wheats the presence of a dominant allele of at least one VRN1 gene homologue (Vrn-A1, Vrn-B1, Vrn-G1 or ...

In-Depth Sequence Analysis of Bread Wheat VRN1 Genes [PDF]
International Journal of Molecular Sciences, 2021 The VERNALIZATION1 (VRN1) gene encodes a MADS-box transcription factor and plays an important role in the cold-induced transition from the vegetative to reproductive stage. Allelic variability of VRN1 homoeologs has been associated with large differences in flowering time.

American Journal of Plant Sciences, 2021 In cereal species such as wheat (Ttiticum aestivum) and barley (Hordeum vulgare), many studies have indicated that VERNALIZATION 1 (VRN1) functions as a flowering promoter, which activates florigen gene expression. The wheat florigen gene Wheat FLOWERING LOCUS T (WFT, which is identical to VRN3) is an integrator of the vernalization, photoperiod ...

Effect of Photoperiod on the Regulation of Wheat Vernalization Genes VRN1 and VRN2 [PDF]
Plant Molecular Biology, 2006 Wheat is usually classified as a long day (LD) plant because most varieties flower earlier when exposed to longer days. In addition to LD, winter wheats require a long exposure to low temperatures (vernalization) to become competent for flowering. Here we show that in some genotypes this vernalization requirement can be replaced by interrupting the LD ...

Targets and mechanisms of epigenetic regulation in the temperate cereal vernalisation process [PDF]
Frontiers in Plant ScienceVernalisation is a prolonged cold exposure that synchronises flowering with favourable seasonal conditions, protecting reproductive development from winter stress and optimising crop yields.

Analysis of VRN1 gene in triticale and common wheat genetic background [PDF]
Scientia Agricola, 2014 In cereals, the transition from the vegetative stage to flowering is controlled in the main by the set of vernalization genes. Within these genes the most important role is played by VRN1, which encodes a MADS-box transcription factor, regulating the ...

The Regulatory Roles of Intrinsically Disordered Linker in VRN1-DNA Phase Separation
International Journal of Molecular Sciences, 2022 Biomacromolecules often form condensates to function in cells. VRN1 is a transcriptional repressor that plays a key role in plant vernalization. Containing two DNA-binding domains connected by an intrinsically disordered linker (IDL), VRN1 was shown to undergo liquid-like phase separation with DNA, and the length and charge pattern of IDL play major ...

O-GlcNAc and phosphorylation modifications on HtL1/FBA10 regulate wheat vernalization for flowering [PDF]
Nature CommunicationsVernalization-regulated flowering is vital for wheat yield and geographical distribution, and the diversity of flowering time genes is essential for the breeding of climate-resilient varieties.
