Transcriptome Profiling Identifies Key Regulators of Tuber Skin Color in Potato.

ABSTRACT: The color of tuber skin exhibits remarkable diversity in potato (Solanum tuberosum L.) and is intricately associated with variance in anthocyanin accumulation across different varieties. The regulatory mechanisms governing this phenomenon are poorly understood. In this study, we identified a natural, yellow-skinned variant (Z28M) from the red-skinned tetraploid variety, Zhongshu 28 (Z28W), using simple sequence repeat (SSR) molecular marker amplification and trait observation. The transcriptional regulatory mechanisms underlying tuber skin color variation were investigated by analyzing anthocyanin profiles and transcriptomic data at the developmental and maturation stages. Ultra-performance liquid chromatography (UPLC-QTOF-MS) analysis indicated markedly reduced levels of pelargonid
