  abstract = {{S}-1 is the most important locus acting as a reproductive barrier between {O}ryza sativa and {O}. glaberrima. {I}t is a complex locus, with factors that may affect male and female fertility separately. {R}ecently, the component causing the allelic elimination of pollen was fine mapped. {H}owever, the position and nature of the component causing female sterility remains unknown. {T}o fine map the factor of the {S}-1 locus affecting female fertility, we developed a mapping approach based on the evaluation of the degree of female transmission ratio distortion (f{TRD}) of markers. {T}hrough implementing this methodology in four {O}. sativa 3 {O}. glaberrima crosses, the female component of the {S}-1 locus was mapped into a 27.8-kb ({O}. sativa) and 50.3-kb ({O}. glaberrima) region included within the interval bearing the male component of the locus. {M}oreover, evidence of additional factors interacting with {S}-1 was also found. {I}n light of the available data, a model where incompatibilities in epistatic interactions between {S}-1 and the additional factors are the cause of the female sterility barrier between {O}. sativa and {O}. glaberrima was developed to explain the female sterility and the {TRD} mediated by {S}-1. {A}ccording to our model, the recombination ratio and allelic combinations between these factors would determine the final allelic frequencies observed for a given cross.},
