ZF1 — Cucumis sativus

Summary

CsZF1 (ZF1) on cucumber chromosome 2 encodes a C2H2 zinc-finger protein of the AZF1/2/3-like family and is annotated with DNA-binding transcription factor activity, histone H3K4 methylase activity, and transcription corepressor binding. The gene is associated with sex differentiation and determination, stamen development, and regulation of stomatal complex patterning. It is linked to fruit quality and length, seed coat and sepal morphology, adventitious and lateral root number and length, root meristem development, phosphorus uptake, jasmonic acid sensitivity and content, ethylene sensitivity, anthocyanin content, and responses to freezing, osmotic stress, UV-B light, and insect damage. Additional associations include drought tolerance, cold and salt stress responses, ABA signaling, disease resistance, seed dormancy, flowering time, and phosphate homeostasis. Studies of related genes in other species link the family to anthocyanin and flavonoid biosynthesis, freezing stress resistance, root architecture, and pathogen responses.
