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 <i>qPL8</i>, 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 parents, 17 genes were identified with SNPs
or InDels variations in the coding region. Expression analysis showed that eight genes were up-regulated in the
NIL with <i>qPL8</i>. Considering both the coding variation and expression status, several candidate genes for the locus
were identified, and <i>OsMADS37</i> was raised as the most possible candidate. Interestingly, an expression QTL
(eQTL) also resides in the locus, leading to a cluster of gene expression variation in the region. This study will
facilitate the application of <i>qPL8</i> locus in rice breeding for yield potential.},
