STZ — Phaseolus vulgaris

Summary

PHAVU_009G070800, designated PvSTZ, encodes a C2H2-type zinc finger transcription factor of the AZF1/2/3-like family on chromosome 9 of French bean. The product possesses DNA-binding, transcription corepressor, protein kinase, and histone H3K4 methylase activities, and localises to the nucleus, cytoplasm, stress granules, and the preprophase band. PvSTZ is associated with multicellular organism growth, photoprotection, gibberellic acid homeostasis, regulation of root development and stomatal patterning, phosphate homeostasis, and jasmonic acid-mediated systemic resistance. It has been linked to traits including photosynthetic rate, anthocyanin content, lateral root number and length, seed coat and sepal morphology, anther and inflorescence development, and responses to water stress, UV-B light, osmotic stress, ethylene, and brassinosteroids. Studies of related genes in other species connect the family to salt and freezing tolerance, phosphate homeostasis, and cadmium accumulation.
