Fine mapping of pds1 and the expression analysis of its candidate genes and spikelet development related gene at spikelet development stage In5, 6, and 7 of S142, 430, and pds plant. a Preliminary mapping of pds1. b Physical map of the pds1 locus. Two key recombinants delimited the mapping region. c Putative ORFs in the mapping region. d The expression level of candidate gene Loc_Os08g05950. e The expression level of candidate gene Loc_Os08g05940. f The expression level of G1 gene. Red color IDs in (c) indicate the candidates with significant differential expression between pds plant and its parents; Blue color IDs in (c) indicate the candidates did not show significant expression between pds plant and its parents; Black color IDs in (c) indicate the expressions of candidates were undetectable in pds plant and its parents
