STZ — Pisum sativum

Summary

PSAT6G016400 (symbol STZ, also known as ZAT6, ZF3, and C2H2) on garden pea chromosome 6LG2 encodes a C2H2-type zinc finger transcription factor of the AZF1/2/3-like family. The product exhibits DNA-binding transcription factor activity, RNA polymerase II cis-regulatory region sequence-specific DNA binding, transcription corepressor activity, and histone H3K4 methylase activity. It is associated with multicellular organism growth, leaf formation, regulation of root development and root meristem size, stomatal complex patterning, photoprotection, gibberellic acid homeostasis, phosphate homeostasis, camalexin anabolism, and induced systemic resistance, jasmonic acid mediated signaling pathway. The gene has been linked to numerous agronomic traits including photosynthetic rate, phosphorus uptake, lateral root number and length, adventitious root number, seed coat and sepal morphology, anther morphology, stamen length, shoot axis branching, and responses to UV-B light, osmotic response sensitivity, ethylene sensitivity, brassinosteroid sensitivity, and insect damage response trait. Studies of related genes in other species connect the family to salt and freezing stress tolerance, phosphate homeostasis, and cadmium accumulation, as well as abiotic stress tolerance, cold stress signaling, and herbivory resistance.
