RAB — Brassica oleracea

Summary

BoRAB (BOLC102_C09P074140.1) on cabbage chromosome 9 encodes a C2H2 zinc-finger transcription factor with a plant development regulator domain. It is associated with DNA-binding transcription factor activity and localises to the nucleus. The gene has been linked to regulation of meristem organisation, response to cold, sporulation, spore germination, homologous recombination, secretion, vesicle transport, and regulation of DNA-templated transcription. Associations with traits include germination rate, and with phenotypes such as altered floral organ development (reduced second-whorl organs, extra sepals, reduced petals with staminoid characteristics), cytokinesis, cell geometry, hypocotyl growth, cellulose biosynthesis, and endoplasmic reticulum trafficking. Studies of related genes in other species link the family to petal size, petal morphology, floral organ development, organ identity, cellulose content, and hypocotyl morphology traits.
