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
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 ...

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.

Biologia Plantarum, 2013 Most perennial and winter annual temperate grasses have a vernalization requirement (VR) for flowering, that is, they require a cold period before they can flower in response to long days.

Vernalization requirement and the chromosomal VRN1-region can affect freezing tolerance and expression of cold-regulated genes in Festuca pratensis [PDF]
Frontiers in Plant Science, 2016 Plants adapted to cold winters go through annual cycles of gain followed by loss of freezing tolerance (cold acclimation and deacclimation). Warm spells during winter and early spring can cause deacclimation, and if temperatures drop, freezing damage may

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 ...

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,

Epigenetic control on transcription of vernalization genes and whole-genome gene expression profile induced by vernalization in common wheat [PDF]
Plant DiversityVernalization is necessary for winter wheat to flower. However, it is unclear whether vernalization is also required for spring wheat, which is frequently sown in fall, and what molecular mechanisms underlie the vernalization response in wheat varieties.

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.
