STZ — Pisum sativum

Summary

PSAT5G038120 (STZ, also known as ZAT6, ZF3, or C2H2) on garden pea chromosome 5LG3 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, photoprotection, gibberellic acid homeostasis, phosphate homeostasis, and priming of cellular response to stress. The gene is linked to traits including photosynthetic rate, phosphorus uptake, lateral root number and length, adventitious root number, seed coat and sepal morphology, anther morphology, jasmonic acid sensitivity and content, UV-B light sensitivity, osmotic response sensitivity, and wheat powdery mildew disease response. Studies of related genes in other species link the family to salt and freezing stress tolerance, phosphate homeostasis, and auxin signaling.
