CXE14 — Brassica napus

Summary

BnCXE14 (also known as GID1B) on chromosome A09 of oilseed rape encodes a protein with carboxylesterase activity and gibberellin binding, belonging to the alpha/beta hydrolase fold family and the carboxylest/gibberellin receptor domain. The gene is associated with gibberellin-mediated signalling, floral organ morphogenesis, regulation of leaf morphogenesis, and responses to strigolactone, light quality, and temperature stress. It has been linked to traits including stem length, seed set, photosynthetic ability, plant male sterility, photoperiod-sensitive flowering time, and phenolic compound content. Localisation evidence connects the product to the nucleus, cytosol, and amyloplast. Studies of related genes in other species link the family to dwarfism, delayed flowering, reduced seed yield, and germination defects requiring seed coat removal.
