CDPK — Solanum tuberosum

Summary

PGSC0003DMG400027877 (CDPK, StCDPK3) on potato chromosome 12 encodes a non-specific serine/threonine protein kinase with EF-hand calcium-binding domains, calmodulin-binding activity, and calcium-dependent protein serine/threonine kinase activity (EC 2.7.11.1). This gene is associated with drought response, tuber development, and organ growth in potato. It is linked to calcium signaling, stomatal closure, response to water, wound healing, hormone metabolism, starch metabolism, sucrose metabolism, fatty acid metabolism, glycerolipid metabolism, chlorophyll anabolism, cytokinesis, and sporulation. The encoded protein localizes to the membrane, cytoplasm, and nucleus. The gene is associated with traits including drought tolerance, net photosynthetic rate, stomatal resistance, relative chlorophyll content, seedling height, tuber morphology, starch content, soluble protein content, nitrogen content, proline content, germination rate, and seed maturation. Studies of related genes in other species further connect this gene family to calcium signaling and stress responses.
