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 ...

Wheat TILLING Mutants Show That the Vernalization Gene VRN1 Down-Regulates the Flowering Repressor VRN2 in Leaves but Is Not Essential for Flowering [PDF]
PLoS Genetics, 2012 Most of the natural variation in wheat vernalization response is determined by allelic differences in the MADS-box transcription factor VERNALIZATION1 (VRN1). Extended exposures to low temperatures during the winter (vernalization) induce VRN1 expression

Cytoplasm of the Wild Species Aegilops mutica Reduces VRN1 Gene Expression in Early Growth of Cultivated Wheat: Prospects for Using Alloplasmic Lines to Breed Varieties Adapted to Global Warming [PDF]
PlantsIn a warm winter due to climate warming, it is necessary to suppress early flowering of autumn-sown wheat plants. Here, we propose the use of cytoplasmic genome effects for this purpose.

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.

Cold-induced nucleosome dynamics linked to silencing of Arabidopsis FLC [PDF]
Nature CommunicationsTemperature influences nucleosome dynamics, and thus chromatin, to regulate gene expression. Such mechanisms underlie the epigenetic silencing of Arabidopsis FLOWERING LOCUS C (FLC) by prolonged cold.

Breeding potential of Spanish bread wheat landraces: genetic variability in vernalization and photoperiod sensitivity [PDF]
Frontiers in Plant ScienceFlowering time and grain filling, regulated by temperature-responsive (vernalization) and day length (photoperiod) genes, are critical factors in wheat production. In this study, we analyzed genetic variation at the VRN-A1, VRN-B1, PPD-A1, PPD-B1, PPD-D1,

Ambient temperature influenced co-expression network of major developmental, circadian, and photoreceptor genes in bread wheat [PDF]
Scientific ReportsThe developmental process of bread wheat comprises of two major phases: the generative development of the apices from double ridge to terminal spikelet formation, followed by the intensive stem elongation.
