AL2 — Brassica oleracea var. botrytis

Summary

BoAL2, located on chromosome 3 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, chromatin organization, and epigenetic downregulation of gene expression. It is linked to root hair elongation, root development, cellular response to phosphate starvation, and cellular monoatomic cation homeostasis. BoAL2 is associated with traits including flowering time, vegetative to reproductive phase transition, seed growth and development, carpel and root morphology, hypocotyl morphology, and sensitivity to abscisic acid and jasmonic acid. The protein localizes to the nucleus, cytoplasm, mitochondria, and PRC1 complex. Related genes in other species link the family to seed germination, dormancy, thermoinhibition, and phosphate homeostasis.
