Transition of aromatic volatile and transcriptome profiles during melon fruit ripening

Melon (Cucumis melo L.) is an important diploid crop with a wide variety of flavors due to its distinct aromatic volatile organic compounds (VOC). To understand the development VOC profiles during fruit development, we performed metabolomic and transcriptomic analysis two cantaloupe varieties over course development. A total 130 metabolites were detected in samples, 449014207 reads mapped melon genome. 4469 differentially expressed genes fruits identified used visualize transition shift both was observed from early-fruit enriched C5-C8 lipid-derived VOCs late-fruit abundant C9 VOCs, apocarotenoids, esters. The coincided expression specific isoforms lipid carotenoid metabolizing enzymes as well transcription factors involved ripening, metabolite regulation, hormone signaling.
