Fine-mapping of OsSRF8 . The molecular markers and numbers of recombinants are noted. OsSRF8 is located on chromosome 2 with seventeen predicted ORFs in the interval between the markers DY-9 and DY-15. LOC_Os02g10110 is identified as the candidate gene. Mutant Ossrf8 harbors (G-A) single substitution results in premature translation termination. ATG, start codon; TAA, stop codon.
