SPL2 — Oryza sativa Japonica

Summary

OsSPL2 (Os06G0703500) encodes an SBP-domain transcription factor with DNA-binding and transcription activator activity, localised to the nucleus. In rice, it is associated with wax metabolism, inositol phosphate metabolism, negative regulation of auxin metabolism, pre-harvest sprouting, leaf shaping, stomatal closure, cell wall modification, abscission, and temperature compensation of the circadian clock. It is also linked to photoperiod-sensitive flowering time, panicle length, tiller number, grain number and size, plant height, vegetative vigor, and responses to abiotic stress, oxidative stress, and low temperature. Additional associations include spot blotch disease tolerance, herbicide sensitivity, and chloroplast development. Studies of related genes in other species link the family to vegetative phase change, inflorescence architecture, and photoperiodic flowering.
