STZ — Brassica oleracea var. botrytis

Summary

BoSTZ (STZ, ZAT10) on cauliflower chromosome 3 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 multicellular organism growth, photoprotection, de-etiolation, regulation of stomatal complex patterning, gibberellic acid homeostasis, response to freezing, high light intensity and L-glutamate, jasmonic acid-mediated systemic resistance, camalexin anabolism, and root meristem size regulation. The gene has been linked to carotenoid content, anthocyanin content, seed coat and sepal morphology, adventitious root number, inflorescence development, anther and stamen traits, shoot branching, leaf morphology, chloroplast development, cell cycle, pollen fertility, phosphorus uptake, UV-B sensitivity, osmotic and ethylene sensitivity, and abiotic stress response. Related genes in other species are linked to drought, cold, heat, salt, oxidative stress tolerance, innate immunity, herbivore defense, stomatal aperture, and stress priming.
