D14 — Oryza sativa Indica Group

Summary

BGIOSGA012067 (OiD14) encodes an alpha/beta hydrolase-fold protein with esterase activity, annotated as a strigolactone receptor in Indica rice. The gene is associated with strigolactone response and anabolism, shoot morphogenesis, secondary shoot formation, tiller development, and regulation of meristem organisation. It is linked to auxin polar transport, de-etiolation, cuticle development, leaf senescence, seed germination suppression, karrikin response, arbuscular mycorrhizae formation, and drought response. Localisation evidence links the protein to the cytosol, nucleus, and SCF ubiquitin ligase complex. Associations with agronomic traits include grain yield, plant height, seed-setting rate, bacterial blight disease resistance, heat tolerance, drought stress sensitivity, nitrogen deficiency response, and oxidative stress response. Studies of related genes in other species link the family to plant branching, flowering time, root development, and abiotic stress tolerance.
