STZ — Brassica oleracea var. botrytis

Summary

BoSTZ (STZ, ZAT10) on cauliflower chromosome 5 encodes a C2H2 zinc-finger protein of the AZF1/2/3-like family with DNA-binding, transcription corepressor, protein kinase and phosphatase-binding activities. It is associated with responses to high light intensity, freezing, L-glutamate, and jasmonic acid, as well as photoprotection, de-etiolation, gibberellic acid homeostasis, regulation of stomatal complex patterning, root meristem size, and unidimensional cell growth. The gene is linked to carotenoid and anthocyanin content, sepal, seed coat, anther, leaf and inflorescence morphology, adventitious root number, phosphorus uptake, UV-B sensitivity, osmotic and low-temperature stress responses, and plant growth, herbivory resistance, cadmium tolerance, salinity tolerance, and systemic acquired acclimation. Related genes in other species are associated with drought tolerance, cold acclimation, innate immunity, and resistance to Botrytis cinerea.
