INO — Brassica oleracea var. botrytis

Summary

BoINO, located on chromosome 7 of cauliflower (Brassica oleracea var. botrytis), encodes a YABBY family protein with DNA-binding, zinc-binding, and transcription cis-regulatory region-binding activities. This nuclear protein is associated with carpel formation, nectary development, regionalization, style development, specification of carpel identity, sporocyte differentiation, regulation of shoot apical meristem development, cell fate commitment, abaxial cell fate specification, regulation of developmental process, meristem determinacy, polarity specification of adaxial/abaxial axis, carpel development, regulation of leaf development, specification of floral organ number, fruit development, floral meristem determinacy, and plant ovule development. BoINO is linked to traits including microsporocyte development, leaf position, anther morphology, plant morphology, shoot apical meristem development, pollen fertility restoration, leaf morphology, leaf composition, and flowering time, as well as phenotypes such as seed iron accumulation, outer integument growth, female sterility with absent outer ovule integument, male fertility, microsporocyte generation, leaf initiation, adaxial-abaxial axis patterning during ovule development, flowering time, anther development, anther wall formation, complete male and female sterility with defective sporocyte formation, microsporocyte differentiation, absence of megaspores and microspores, leaf complexity, anther morphogenesis, juvenile traits, shoot apical dominance, vascular development, microsporogenesis,
