RF6 — Oryza sativa Indica Group

Summary

BGIOSGA027862 (RF6, OiRF6) on chromosome 8 of Indica rice encodes an uncharacterized protein with a Mito_RNA-Proc/Resp domain, PPR repeats, and a TPR-like helical domain superfamily, and is annotated for mRNA binding and identical protein binding. The gene is directly associated with cytoplasmic male sterility restoration, male sterility, and sterility phenotypes in this species, and is linked to RNA metabolism, mRNA stabilization, mRNA processing, and positive regulation of translation. It localizes to mitochondria and chloroplast stroma. Associations also include heterosis, fertility restoration, pollen development, seed traits, abiotic stress tolerance, and breeding. Studies of related genes in other species link the family to RNA processing in organelles.
