Positional cloning of the wheat vernalization gene VRN1
Winter wheats require several weeks at low temperature to flower. This process, vernalization, is controlled mainly by the VRN1 gene. Using 6,190 gametes, we found VRN1 to be completely linked to… Expand

Winter wheat and barley varieties require an extended exposure to low temperatures to accelerate flowering (vernalization), whereas spring varieties do not have this requirement. In this study, we… Expand

Characterization of polyploid wheat genomic diversity using a high-density 90 000 single nucleotide polymorphism array
High-density single nucleotide polymorphism (SNP) genotyping arrays are a powerful tool for studying genomic patterns of diversity, inferring ancestral relationships between individuals in… Expand

A NAC Gene Regulating Senescence Improves Grain Protein, Zinc, and Iron Content in Wheat
Enhancing the nutritional value of food crops is a means of improving human nutrition and health. We report here the positional cloning of Gpc-B1, a wheat quantitative trait locus associated with… Expand

The Wheat VRN2 Gene Is a Flowering Repressor Down-Regulated by Vernalization
Plants with a winter growth habit flower earlier when exposed for several weeks to cold temperatures, a process called vernalization. We report here the positional cloning of the wheat vernalization… Expand

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… Expand

Allelic variation at the VRN-1 promoter region in polyploid wheat
Vernalization, the requirement of a long exposure to low temperatures to induce flowering, is an essential adaptation of plants to cold winters. We have shown recently that the vernalization gene… Expand

Genome-wide comparative diversity uncovers multiple targets of selection for improvement in hexaploid wheat landraces and cultivars
Domesticated crops experience strong human-mediated selection aimed at developing high-yielding varieties adapted to local conditions. To detect regions of the wheat genome subject to selection… Expand

The HAK1 gene of barley is a member of a large gene family and encodes a high-affinity potassium transporter.
The high-affinity K+ uptake system of plants plays a crucial role in nutrition and has been the subject of extensive kinetic studies. However, major components of this system remain to be identified.… Expand

A Kinase-START Gene Confers Temperature-Dependent Resistance to Wheat Stripe Rust
Stripe rust is a devastating fungal disease that afflicts wheat in many regions of the world. New races of Puccinia striiformis, the pathogen responsible for this disease, have overcome most of the… Expand
