STZ — Medicago truncatula

Summary

MTR_1G018420 (MtSTZ) encodes a C2H2-type zinc finger transcription factor of the AZF1/2/3-like family, possessing DNA-binding, transcription corepressor activity, histone H3K4 methylase activity, and protein kinase activity. It is associated with multicellular organism growth, cell wall thickening, xylem development, photoprotection, and regulation of root development. The gene is linked to phosphorus uptake, lateral root number and length, adventitious root number, photosynthetic rate, anthocyanin content, and responses to jasmonic acid, ethylene, UV-B light, and osmotic stress. Associations also include seed coat and sepal morphology, floral organ number, inflorescence development, anther morphology, stamen length, and wheat powdery mildew disease response. Studies of related genes in other species connect the family to salt and freezing stress tolerance, drought tolerance, anthocyanin biosynthesis, and resistance to herbivory and Botrytis cinerea.
