Abstract Grain yield and grain quality are major determinants in modern breeding controlled by many quantitative traits loci (QTLs) rice (Oryza sativa). However, the mechanisms underlying shape poorly understood. Here, we characterize a QTL for size via map-based cloning from wild (W1943), GS10 (Grain Size on Chromosome 10), which encodes protein with 6 tandem armadillo repeats. The null mutant gs10 shows slender narrow grains altered cell size, has pleiotropic effect other agronomical...
Abstract Wild rice (Oryza rufipogon) has a lower panicle seed setting rate (PSSR) and gamete fertility than domesticated sativa), but the genetic mechanisms of this phenomenon remain unknown. Here, we cloned null allele OsMLH1, an ortholog MutL-homolog 1 to yeast mammals, from wild O. rufipogon W1943 revealed 5.4-kb retrotransposon insertion in OsMLH1 is responsible for low PSSR rice. In contrast wild-type, near isogenic line NIL-mlh1 exhibits defective crossover (CO) formation during...
