Article Synopsis
- - The study focuses on identifying genetic factors that enhance frost tolerance (FroT) in winter wheat, which is crucial for improving crop yields in areas prone to heavy frost.
- - Researchers conducted genome-wide association studies (GWAS) on 276 winter wheat genotypes, leading to the identification of 53 significant markers linked to FroT across 23 QTL regions on 11 chromosomes.
- - Importantly, the study discovered eight previously unknown FroT QTLs, providing new insights into the genetic mechanisms of frost resistance in wheat and potential strategies for breeding frost-tolerant varieties.
Association genetics studies on frost tolerance in wheat (Triticum aestivum L.) reveal new highly conserved amino acid substitutions in CBF-A3, CBF-A15, VRN3 and PPD1 genes.

Background: Understanding the genetic basis of frost tolerance (FT) in wheat (Triticum aestivum L.) is essential for preventing yield losses caused by frost due to cellular damage, dehydration and reduced metabolism. FT is a complex trait regulated by a number of genes and several gene families.

Diacylglycerol kinase (DGK) regulates the level of the second messenger diacylglycerol and produces phosphatidic acid (PA), another signaling molecule. The Arabidopsis thaliana genome encodes seven putative diacylglycerol kinase isozymes (named AtDGK1 to -7), structurally falling into three major clusters. So far, enzymatic activity has not been reported for any plant Cluster II DGK.
