CXE14 — Brassica napus

Summary

BnCXE14 (also known as GID1B) on chromosome C08 encodes a protein with carboxylesterase activity and gibberellin binding capacity, belonging to the alpha/beta hydrolase fold family. This gene is associated with gibberellin-mediated signalling, floral organ morphogenesis, and regulation of leaf morphogenesis. It has been linked to numerous agronomically important traits including stem length, seed set percent, plant male sterility, anther and stamen morphology, fruit growth and development, whole plant size, shoot system elongation rate, and photosynthetic ability. Associations also extend to responses to light quality, temperature stress, strigolactone, and viral disease, as well as phenolic compound content and root oxidative activity. The protein localises to the nucleus, cytosol, and amyloplast. Related genes in other species are linked to dwarfism, delayed flowering, reduced seed yield, and germination defects.
