Multi-omics insights into high-carotenoid hybrid potato lines enhanced nutritional quality and metabolic regulation for food applications
Modern potato varieties often exhibit low carotenoid content, limiting their nutritional value and processing performance. This study employed a multi-omics approach (physicochemical analysis, metabolomics, mineral profiling, transcriptomics, and microbiome sequencing) to investigate the molecular basis of high-carotenoid biofortification in two elite hybrid potato lines (H4 and H14) compared with four commercial cultivars.
