Genbank accession number

• A drus1-1 drus2 double knockout mutant, but not either single mutant, showed extreme dwarfism and barren inflorescences that harbored sterile spikelets
• We observed that both FLR1 and FLR2 were involved in tillering of rice, but at different levels
• Interestingly, FLR1 and FLR2 showed different functions related to fertility, and FLR1 might be specifically involved in rice male gametophyte development
• In this study, we generated flr1 and flr2 T-DNA insertion null mutants and investigated potential role of FLRs in rice yield
• With these similar but different functions, we suggest that FLR1 and FLR2 might function in complementary ways to regulate the yield of rice

• DRUS2~FLR2, FLR11, Mutations of two FERONIA-like receptor genes enhance rice blast resistance without growth penalty., Using these genetic resources, we found that mutations in the FLR2 and FLR11 genes provide resistance to rice blast without a profound growth penalty
• DRUS1~FLR1, DRUS2~FLR2, Roles of FERONIA-like receptor genes in regulating grain size and quality in rice, We found that FLR1, FLR2 and FLR8 negatively regulated grain size, and FLR15 positively regulated grain size
