Lineage-specific gene acquisition or loss is involved in interspecific hybrid sterility in rice.

ABSTRACT: Understanding the genetic basis of reproductive barriers between species has been a central issue in evolutionary biology. The S₁ locus in rice causes hybrid sterility and is a major reproductive barrier between two rice species, Oryza sativa and Oryza glaberrima The O. glaberrima-derived allele (denoted S₁^g) on the S₁ locus causes preferential abortion of gametes with its allelic alternative (denoted S₁^s) in S₁^g/S₁^s heterozygotes. Here, we used mutagenesis and screening of fertile hybrid plants to isolate a mutant with an allele, S₁^mut, which does not conf
