RAB — Brassica oleracea var. botrytis

Summary

BoRAB (BOLND125_C09P074290.1_BOLND125_V1) on cauliflower chromosome 9 encodes a C2H2-type zinc-finger transcription factor with DNA-binding activity, belonging to the plant development regulator family. The protein localises to the nucleus and is associated with endocytosis, regulation of meristem organisation, response to cold, and regulation of transcription. Phenotypic associations include floral organogenesis, organ separation, cytokinesis, cell geometry, hypocotyl growth, cellulose biosynthesis, and endoplasmic reticulum trafficking. The gene is linked to reduced second-whorl organs, fewer filaments, extra sepals with fusion, reduced petals with staminoid characteristics, and uneven sepal growth. Related genes in other species are associated with petal development, petal size, floral organ development, directional cell growth, vesicular transport, germination rate, and cellulose content.
