ZF1 — Cucumis melo

Summary

MELO3C010813.2 (CmZF1) on melon chromosome 4 encodes a C2H2 zinc-finger transcription factor of the AZF1/2/3-like family, with annotated histone H3K4 methylase activity, DNA-binding and transcription corepressor-binding functions. The gene is associated with regulation of root development, stomatal complex patterning and closure, stress priming, and responses to freezing, hyperosmotic salinity and L-glutamate. It is linked to phosphate homeostasis, galactose metabolism, triterpenoid and camalexin anabolism, and jasmonic acid-mediated induced systemic resistance. Associations include fruit size, seed coat morphology, adventitious and lateral root number, shoot branching, phosphorus uptake, UV-B sensitivity, anthocyanin content, and ethylene and jasmonic acid sensitivity. Studies of related genes in other species connect the family to anthocyanin and flavonoid biosynthesis, freezing stress resistance, root architecture, and resistance to Botrytis cinerea.
