Positional cloning of the wheat vernalization gene VRN1
The results suggest that AP1 is a better candidate for VRN1 than AGLG1, and the epistatic interactions between vernalization genesVRN1 and VRN2 suggested a model in whichVRN2 would repress directly or indirectly the expression of AP1.

It is shown that in these species, the vernalization gene VRN3 is linked completely to a gene similar to Arabidopsis FLOWERING LOCUS T (FT), which results in a transmissible signal that promotes flowering.
Characterization of polyploid wheat genomic diversity using a high-density 90 000 single nucleotide polymorphism array
The developed array and cluster identification algorithms provide an opportunity to infer detailed haplotype structure in polyploid wheat and will serve as an invaluable resource for diversity studies and investigating the genetic basis of trait variation in wheat.
The Wheat VRN2 Gene Is a Flowering Repressor Down-Regulated by Vernalization
Cutting the RNA level of VRN2 by RNA interference accelerated the flowering time of transgenic winter-wheat plants by more than a month and resulted in spring lines, which do not require vernalization to flower.
A NAC Gene Regulating Senescence Improves Grain Protein, Zinc, and Iron Content in Wheat
The positional cloning of Gpc-B1, a wheat quantitative trait locus associated with increased grain protein, zinc, and iron content, is reported here, and reduction in RNA levels of the multiple NAM homologs by RNA interference delayed senescence by more than 3 weeks and reduced wheat grain protein and zinc content.
Allelic variation at the VRN-1 promoter region in polyploid wheat
It is concluded that the VRN-1 genes should have additional regulatory sites outside the promoter region studied here, as there are no size polymorphisms in the promoter area among the winter wheat varieties.
Large deletions within the first intron in VRN-1 are associated with spring growth habit in barley and wheat
The broad adaptability of wheat and barley is in part attributable to their flexible growth habit, in that spring forms have recurrently evolved from the ancestral winter growth habit. In diploid
Regulation of flowering in temperate cereals.
Genome-wide comparative diversity uncovers multiple targets of selection for improvement in hexaploid wheat landraces and cultivars
It is shown that selection likely acts on distinct targets or multiple functionally equivalent alleles in different portions of the geographic range of wheat, suggesting either weak selection pressure or temporal variation in the targets of directional selection during breeding probably associated with changing agricultural practices or environmental conditions.
The HAK1 gene of barley is a member of a large gene family and encodes a high-affinity potassium transporter.
A cDNA from barley roots was isolated, HvHAK1, whose translated sequence shows homology to the Escherichia coli Kup and Schwanniomyces occidentalis HAK1 K+ transporters, and analysis of several genomes of Triticeae indicates that it belongs to a multigene family.
