SAF — Oryza sativa Indica Group

Summary

BGIOSGA003822 (SAF, OiSAF) on chromosome 1 of Indica rice encodes an F-box domain-containing protein with an FBD and LRR_FXL15/PEG3-like domain. This gene is associated with pollen development, as annotated by ontology terms. It has been linked to heterosis and hybrid pollen sterility, including sterility phenotypes described in the context of QPS-1 and E3. Studies of related genes in other species connect the family to hybrid incompatibility, anthesis time, and male sterility, though these associations are not yet established for this rice gene.
