WRKY13 — Glycine max

Summary

GLYMA_05G185400V4, designated GmWRKY13, encodes a WRKY domain-containing transcription factor on soybean chromosome 5. The protein localises to the nucleus and exhibits sequence-specific DNA binding, transcription cis-regulatory region binding, and protein homodimerization activity. GmWRKY13 is associated with the positive regulation of leaf senescence, lateral root development, cell growth, and nitrogen fixation. It has been linked to abscisic acid-mediated signalling in stomatal movement, stress responses to cadmium ions, and the inhibition of defence responses to bacteria. The gene is also connected to glucan metabolism, actin depolymerization, and the regulation of lignin anabolism. Associations with drought tolerance, germination rate, cytokinin content, salt tolerance, cadmium tolerance and accumulation, stem development, and flowering time have been reported. Related genes in other species link the WRKY13 family to leaf senescence, flowering time, stem diameter, and cadmium concentration.
