D14 — Oryza sativa Indica Group

Summary

BGIOSGA010466 (symbol D14, also known as OiD14, OiKAI2, D14L, OiD14L, OiDLK2, KAI2, DLK2) on chromosome 3 of Indica rice encodes a protein with an alpha/beta hydrolase fold and esterase activity, and is associated with protein binding and ubiquitin ligase complexes. The gene is associated with strigolactone and karrikin responses, shoot morphogenesis, tiller development, leaf senescence, auxin polar transport, cuticle development, de-etiolation, seed germination suppression, arbuscular mycorrhizae formation, and drought stress sensitivity. Associations include grain yield, plant height, seed-setting rate, bacterial blight disease resistance, flowering time, anthocyanin content, root development, stomatal resistance, low temperature and oxidative stress responses, and heat tolerance. Studies of related genes in other species link the family to lateral root density, drought resistance, flowering time, plant branching, and abiotic stress tolerance.
