Gene mapping and identification of candidate genes controlling carotenoid accumulation of yellow kernels in foxtail millet.

ABSTRACT:

Background

Kernel color is an important characteristic of foxtail millet (Setaria italica) associated with its market ability, quality, and nutritional value, which is mainly due to the accumulation of carotenoids. Despite its importance, the genetic basis of carotenoid variation in foxtail millet remains largely unexplored. Herein, the molecular mechanisms governing carotenoid accumulation in the kernel of foxtail millet were investigated by an exhaustive methodology encompassing Genome-Wide Association Study (GWAS), Bulk Segregant Analysis sequencing (BSA-seq), and integrated transcriptomic and metabolomic analyses.

Results

The total carotenoid content in kernels across 201 foxtail millet germplasms showed a spectrum of variations, which indicated that the kernel color is
