BOL — Brassica oleracea var. botrytis

Summary

BoBOL (BOLND125_C03P070980.1_BOLND125_V1) on cauliflower chromosome 3 encodes a DNA-binding transcription factor with an AP2/ERF domain, also annotated for lipid binding, protein dimerization, and identical protein binding activities. The gene is associated with a wide range of developmental processes including meristem initiation, floral meristem determinacy, embryonic pattern specification, adaxial/abaxial axis polarity, plant organ morphogenesis, and integument development. It is linked to responses to cytokinin, ethylene signalling, and stress, as well as to shade avoidance upregulation and cell cycle modulation. The protein localises to both the nucleus and cytosol. Associations with agronomically relevant traits include yield, leaf and root morphology, anther and floral organ identity, seed maturation, shoot and root meristem development, auxin and brassinosteroid sensitivity, and salt tolerance. Studies of related genes in other species connect the family to embryo patterning, organ initiation, shoot regeneration, and auxin transport.
