GAZ — Brassica oleracea var. botrytis

Summary

BoGAZ (GAZ, GAL2, GAL1) on cauliflower chromosome 7 encodes a C2H2-type zinc-finger protein with DNA-binding transcription factor activity and is localised to the nucleus. It is associated with root radial pattern formation, regulation of DNA-templated transcription, and response to salt stress, including a specific link to the SALTTL trait. The gene has also been connected to galactose metabolism and, through the TEB-1 locus, to phenotypes such as short root, reduced aerial growth, serrated asymmetric leaves, and fasciated stem. Studies of related genes in other species link the family to phosphate starvation response and insect resistance, while broader sequence similarity connects it to photochemical quenching and insect damage response traits.
