BLR — Brassica oleracea var. botrytis

Summary

BoBLR (BLR) on cauliflower chromosome 9 encodes a homeodomain-containing transcription factor with DNA-binding, RNA-binding and protein dimerization activities, and is annotated with glycine hydroxymethyltransferase activity. The gene is associated with meristem maintenance, floral whorl morphogenesis, inflorescence meristem identity, adaxial/abaxial pattern specification, carpel and xylem development, secondary shoot formation, and negative regulation of auxin signalling. It has been linked to traits including compound leaf and flower morphology, leaf margin serration, seed weight, pedicel and peduncle length, petal number, shoot branching, photoperiod-sensitive flowering time, lignin biosynthesis, and biotic stress. Associations also include organ separation, floral organ abscission, lateral root formation, salt tolerance, photorespiratory metabolism, oxidative and abiotic stress resistance, leaf senescence, and shoot apical meristem maintenance. Related genes in other species are linked to meristematic activity and shoot apical meristem formation.
