<i>SiFTL</i> and <i>SiHd3a</i> are positive regulators of flowering time in sesame (<i>Sesamum indicum</i> L.).

ABSTRACT: Flowering time, a critical trait for crop adaptation, is regulated by plants' ability to sense light signals, which influences gene expression and the transition from vegetative to reproductive growth. In this study, five populations of sesame (Sesamum indicum) were developed by crossing 'Yuzhi 4' with 'BS377' (late-flowering variety). Linkage mapping analysis revealed that a ~400 kb region on chromosome 11 had the most significant and stable effect on flowering time. FLOWERING LOCUS T-like (FTL) and HEADING DATE 3A (Hd3a), located within the candidate region, are associated with flowering time as revealed by RNA-seq and qRT-PCR analyses. Integrated analyses of SiFTL gene structure and transcript level revealed that the absence of SiFTL expr
