Implication

Comparative multi-omic analysis reveals stage-specific cuticle lipid and specialized metabolite biosynthesis in tomato peel, highlighting regulatory networks driving fruit surface development.

Key Points

To characterize the transcriptional networks and metabolic pathways governing fruit surface development and cuticle formation in tomato fruit.
Conducted comparative transcriptome and metabolome profiling on peel and flesh tissues across tomato (Solanum lycopersicum) fruit developmental stages.
Identified peel-enriched metabolites using UPLC-QTOF-MS and GC-MS with flame ionization detection.
Tracked wax-associated promoter activity across fruit tissues using reporter gene constructs driven by the upstream region of SlCER6.
Identified 574 peel-associated transcripts, with 17% involved in cuticular lipid and phenylpropanoid pathways, including Arabidopsis orthologs SHINE2 and MIXTA-LIKE.
Profiled 100 peel-enriched metabolites—including flavonoids, glycoalkaloids, and amyrin-type triterpenoids—revealing that cuticular lipid accumulation precedes phenylpropanoid and flavonoid synthesis.
Observed progressive SlCER6 promoter activation in both fruit exocarp and endocarp tissues throughout development.
