OSK3 — Oryza sativa Japonica

Summary

OsOSK3 (OS03G0253200) on rice chromosome 3 encodes a protein serine/threonine kinase with blue light photoreceptor activity, ATP binding, and protein autophosphorylation capability. It is associated with the blue light signaling pathway, regulation of auxin polar transport, auxin signaling, and signal transduction. The gene has been connected to reproductive structure development, plant organ development, shoot development, root development, and flower development, as well as post-embryonic development and protein phosphorylation. Its product localizes to the plasmalemma, cytoplasm, and nucleus. OsOSK3 is linked to anthesis time and has been connected to resistance and mitochondrial phenotypes. Studies of related genes in other species link the family to grain yield and stomatal opening.
