AL2 — Brassica oleracea var. botrytis

Summary

BoAL2, located on chromosome 1 of cauliflower (Brassica oleracea var. botrytis), encodes a transcriptional co-regulator with histone-binding and transcription cis-regulatory region-binding activities, featuring PHD zinc-finger and Alfin domains. This gene is associated with the maintenance of inflorescence, floral, and shoot apical meristem identity, as well as cell fate determination, root hair elongation, root development, and chromatin organization. It is linked to cellular responses to phosphate starvation, downregulation of gene expression and transcription, and cellular monoatomic cation homeostasis. BoAL2 localizes to the nucleus, cytoplasm, mitochondria, and the PRC1 complex. Trait associations include flowering time, vegetative to reproductive phase transition, seed growth and development, root morphology, hypocotyl morphology, carpel morphology, meristem tissue development, and sensitivity to abscisic acid and jasmonic acid. Related genes in other species are linked to seed germination, dormancy, thermoinhibition, phosphate homeostasis, and root hair formation.
