Abstract Naturally occurring yellow leaf mutants are an important resource for studying pigment content and biosynthesis, as well as related gene expression. In our ongoing cultivation of Rehmannia chingii H. L. Li, we found an off-type yellow plant. The yellowing started with the new leaves and gradually spread downward until the entire plant exhibited a stable shade of yellow. We studied the differences in the chlorophyll and carotenoid content, carotenoid profile, and transcriptome of this yellow-leaf mutant (P2). Compared to the wild-type R. chingii plant (P1), P2 leaves had significantly lower chlorophyll and carotenoid content. LC-MS/MS analysis revealed More >
