The small heat shock proteins (sHSPs) have been found to play acritical role in physiological stress conditions in protectingproteins from irreversible aggregation. To characterize the geneexpression profile of four sHsps with a tandem gene structurearrangement in the domesticated Solanum lycopersicum (Heinz 1706)genome and its wild close relative Solanum pimpinellifolium(LA1589), differential gene expression analysis using RNA-Seq wasconducted in three ripening stages in both cultivars fruits. Genepromoter analysis was performed to explain the heterogeneouspattern of gene expression found for these tandem duplicated sHsps.In silico analysis results contribute to refocus wet experimentanalysis in tomato sHsp family proteins.
