AT3G50500 — Arabidopsis thaliana

Summary

AT3G50500 (SRK2D, also known as SnRK2.2) encodes a non-specific serine/threonine protein kinase with protein kinase activator and phosphatase regulator activities, calcium-dependent kinase activity, and salicylic acid binding. This Arabidopsis thaliana gene on chromosome 3 is associated with water and drought stress responses, chlorophyll breakdown, glucose-mediated signaling, and nitrate import. It has been linked to numerous agronomic traits including drought sensitivity and recovery, leaf water potential, turgor pressure, root branching, starch mobilization, vegetative vigor, seed dormancy and development, flowering time, and fungal disease resistance. The protein localizes to the cytosol, plasma membrane, plastid, mitochondria, and cell wall, and participates in SnRK2 phosphorylation and SLAC1-like anion channel activation pathways. Related genes in other species are linked to tuber induction and microtubule stability.
