Fig. 4From: Quantitative assay of targeted proteome in tomato trichome glandular cells using a large-scale selected reaction monitoring strategyVolcano plots representing tomato trichome gland cell (TGC) protein expression profiles in three different organs of tomato. In the relative quantification with label-free selected reaction monitoring (SRM) assays, 331 peptides representing 221 proteins were quantified and used for t-tests to generate the volcano plot indicating the log2 expression ratio on the X-axis and − log p value on the Y-axis for each peptide. Detailed information of organ-enriched proteins is shown in Additional file 6: Table S4Back to article page
