CDPK — Brachypodium distachyon

Summary

BdCDPK (BRADI_2G53540V3) on Brachypodium distachyon chromosome 2 encodes a transmembrane receptor protein serine/threonine kinase with protein kinase activity, ATP binding, and signaling receptor activity. The protein contains leucine-rich repeats and a Ser-Thr/Tyr kinase catalytic domain. This gene is associated with post-embryonic plant organ development, floral organ development and specification of floral organ number, regulation of meristem organisation and stomatal complex development, gametophyte and embryo sac development, MAPK cascade, hormone-mediated signalling including brassinosteroid detection, and responses to salinity, thirst, and other organisms. It localises to the membrane, plasmalemma, and extracellular region. Associations with drought, salt, leaf, sheath, grain size, starch biosynthesis, ABA response, jasmonic acid, salicylic acid, and flower development have been noted. Studies of related genes in other species link the family to grain yield, plant height, cold tolerance, seed germination, spikelet fertility, stomatal resistance, and disease resistance.
