Integrated Transcriptomic, Proteomic, and Metabolomic Analyses Reveal Mechanisms Underlying Day-Night Differences in Carbohydrate Metabolism between Diploid and Tetraploid Rice.

ABSTRACT: Polyploidy plays a crucial role in plant evolution, as polyploid plants possess larger genomes compared to their diploid counterparts. This genomic expansion leads to changes in gene redundancy and interactions, which alter the physiological metabolism of polyploids. Carbohydrate metabolism is a crucial energy metabolism pathway in plants, significantly impacting plant growth and development. In this study, we employed multi-omics analysis to investigate the differences in carbohydrate metabolism between diploid and tetraploid flag leaves during both day and night periods at the grain-filling stage. Our results revealed significant differences in carbohydrate metabolism between diploid (GFD-2X) and autopolyploid (GFD-4X) rice during both day and night periods. Chromosome doubling resulted
