Abstract Rice panicle is the sink organ where assimilation product accumulates, and its morphology determines the rice yield. Panicle length has been suggested as a yield-related trait, but the genetic factor for its control is still limited. In this study, we carried out fine-mapping of qPL8, a QTL identified for panicle length in our previous work. Near isogenic line (NIL) with qPL8 exhibited elongated panicle without obvious effect on other panicle elements. With five key recombinants from NIL population, the locus was finally narrowed down to a 278-kb region, where 44 genes are annotated. By comparing the genomic sequence of two… More >

Abstract There is a positive correlation between fertility and yield, and the decrease of fertility is bound to a greatly reduced crop yield. Male sterile mutants can be used in hybrid rice. Therefore, rice male sterility has an important value in research and application, and the study of related mutants is also very vital. The mutant ms10 (male sterile 10) reported in this study was induced by ethyl methane sulfonate (EMS) in the indica maintainer line Xinong 1B. There was no significant difference between the ms10 and wild type in the vegetative growth stage. However, in the reproductive growth stage, ms10… More >
