AL2 — Brassica oleracea var. botrytis

Summary

BoAL2, located on chromosome 5 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, chromatin organization, and cellular response to phosphate starvation. It is linked to traits including flowering time, carpel morphology, seed growth and development, root morphology, hypocotyl morphology, vegetative-to-reproductive phase transition, and sensitivity to abscisic acid and jasmonic acid. The gene is also connected to phenotypes such as dwarfed and arrested inflorescence, abnormal leaves, enlarged shoot apical meristem, and phosphate-dependent root hair elongation defects. Related genes in other species are linked to seed germination, dormancy, thermoinhibition, and phosphate homeostasis.
