Human agricultural activities influence the flowering time of turnip in the Qinghai-Tibet Plateau.

ABSTRACT: Tibetan turnip and oilseeds are the most important vegetables cultivated in the Qinghai-Tibet Plateau. Our field observations identified a dominant early-bolting phenotype at the vegetative growth stage in the Tibetan turnip, which was possibly due to cross-pollination contamination from nearby oilseeds. We performed genetic and molecular experiments to explore the main reason for early bolting. We first analyzed gene expression and genomic sequence variation of turnip and oilseed BraFLC2, a gene that acts as a key repressor of flowering in turnip in a dosage-dependent manner. We found that the differences in flowering time and life habits between turnip and oilseeds were closely correlated with the genetic variations in BraFLC2. We further identified that the early-bolting t
