SlMYB76, an SlANS-Repressing R2R3-MYB Transcription Factor, Regulates Anthocyanin Accumulation in 'Black Pearl' Tomato (<i>Solanum lycopersicum</i>).

ABSTRACT: Background/Objectives: Anthocyanins, water-soluble flavonoid pigments with critical roles in plant stress resistance, are not naturally accumulated in cultivated tomato (Solanum lycopersicum) due to an incomplete flavonoid metabolism pathway. In contrast, 'Black Pearl' tomato exhibits distinct peel color transitions (from indigo rose to deep purple-red) during ripening, making it an ideal model for investigating the regulatory mechanisms of anthocyanin synthesis. A comprehensive strategy was employed to elucidate these mechanisms, involving transcriptomic (Illumina HiSeq), metabolomic (UPLC-MS/MS), and functional analyses of the 'Black Pearl' tomato peel across four developmental stages: mature green (S1), coloring (S2), purple immature (S3), and fully ripened (S4).
