BLR — Brassica oleracea var. botrytis

Summary

BoBLR (BLR) on cauliflower chromosome 2 encodes a protein with POX, KN_HD, and homeodomain domains, annotated with DNA-binding transcription factor activity, RNA polymerase II-specific cis-regulatory region binding, and protein homodimerization activity. It is associated with floral whorl morphogenesis, maintenance of inflorescence and floral meristem identity, adaxial/abaxial pattern specification, carpel development, stem cell population maintenance, secondary shoot formation, and xylem development. The gene is linked to negative regulation of auxin-mediated signaling, cytokinin anabolism, glycine metabolism, and L-serine metabolism. Associations include compound leaf morphology, flower and petal morphology, seed weight, photoperiod-sensitive flowering time, shoot axis branching, pedicel length, lignin biosynthesis, biotic stress, and root oxidative activity. Localization evidence connects it to plasmodesmata, microtubule cytoskeleton, and chloroplast thylakoid. Related genes in other species are linked to shoot apical meristem maintenance, organ separation, and lateral root formation.
