STZ — Phaseolus vulgaris

Summary

PHAVU_001G026700 (PvSTZ) on French bean chromosome 1 encodes a C2H2-type zinc finger transcription factor of the AZF1/2/3-like family with DNA-binding, transcription corepressor activity, and histone H3K4 methylase activity. It is associated with multicellular organism growth, pollen-pistil interaction, photoprotection, gibberellic acid homeostasis, and regulation of root development and stomatal complex patterning. The gene is linked to traits including photosynthetic rate, anthocyanin content, jasmonic acid sensitivity, lateral root number and length, seed coat morphology, and responses to high light, UV-B, osmotic stress, and wheat powdery mildew. It is also associated with phosphate homeostasis, camalexin anabolism, and induced systemic resistance, jasmonic acid mediated signaling pathway. Studies of related genes in other species link the family to salt and freezing stress tolerance, drought response, anthocyanin and flavonoid biosynthesis, and resistance to Botrytis cinerea.
