D14 — Oryza sativa Japonica

Summary

Rice D14 (Os03g0203200) encodes an alpha/beta hydrolase-fold protein with esterase activity. The gene is associated with strigolactone response, shoot morphogenesis, tiller development, secondary shoot formation, and regulation of meristem organization. It is linked to grain yield, seed-setting rate, plant height, tiller number, spikelet fertility, grain size, and flowering time. D14 is also associated with bacterial blight disease resistance, drought stress sensitivity, heat tolerance, oxidative stress response, low temperature stress response, and systemic acquired resistance. The protein localizes to the cytosol, nucleus, and SCF ubiquitin ligase complex, and is associated with auxin polar transport, leaf senescence, cuticle development, arbuscular mycorrhizae formation, and nitrate response. Studies of related genes in other species link the family to strigolactone perception, branching, flowering time, and root development.
