DPK1 — triticum aestivum

Summary

TRAESCS7A02G292800 (TaDPK1) on wheat chromosome 7A encodes a dual-specificity protein kinase with MEKK activity, belonging to the Ser/Thr protein kinase family. The gene is associated with diverse biological processes including pre-harvest sprouting, regulation of photosynthesis, stomatal opening, response to water, calcium signaling, auxin-mediated signaling, autophagy, lipid transport, proline and sulfur metabolism, and seed oilbody biogenesis. It is linked to numerous agronomic traits such as grain weight per spike, grain length and width, grain number, ear number, grain protein content, starch content, stem weight, leaf senescence rate, vascular bundle number, days to heading and maturity, net photosynthetic rate, chlorophyll content, water use efficiency, and tolerance to salinity, heat, stripe rust, and stem rust. The protein localizes to the cytoplasm, nucleus, nucleolus, and plasmalemma. Studies of related genes in other species connect the family to embryogenesis, abscisic acid response, drought stress response, plant growth, and seed oil content.
