Multiomics of tomato glandular trichomes reveals distinct features of central carbon metabolism supporting high productivity of specialized metabolites

ABSTRACT: Glandular trichomes (GT) are specialized cell factories that have the capacity to produce large amounts of metabolites which can amount to over 10% of the leaf dry weight. The specific expression of secondary metabolite pathways in glandular trichomes has facilitated their elucidation. However, little is known about the connection between central carbon and specialized metabolism in these cells. To address this question, we used the type VI glandular trichomes from a cultivated (Solanum lycopersicum LA4024) and a wild tomato accession (Solanum habrochaites LA1777) as a model. Our study is based on metabolomics, transcriptomics, proteomics and 13C-labeling datasets of trichome and leaves samples. This comparative analysis allowed us to identify specific features of trichomes in comparison to leaves. Here, the transcript raw and RMA-normalized data is hosted.

Glandular trichomes are metabolic cell factories with the capacity to produce large quantities of secondary metabolites. Little is known about the connection between central carbon metabolism and metabolic productivity for secondary metabolites in glandular trichomes. To address this gap in our knowledge, we performed comparative metabolomics, transcriptomics, proteomics, and 13C-labeling of type VI glandular trichomes and leaves from a cultivated (Solanum lycopersicum LA4024) and a wild (Solanu  ...[more]
