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 >
