The tomato TPS family. (A). Effect of S. indica colonisation on the expression of tomato TPSs in leaves and roots. Changes in gene expression between tissues from inoculated plants and tissues from endophyte-free plants are represented as log2 of the fold change in the form of a heatmap. Data derived from RNA sequencing on leaves and roots from S. indica- and mock-inoculated plants. Asterisks (*) indicate FDR-corrected p ≤ 0.05, apart from TPS32 and TPS33, whichwere expressed only in samples from inoculated roots, and no related transcripts were found in the samples of control roots. (B). Biosynthetic pathways catalysed by the TPSs, the expression of which is affected by S. indica colonisation, are only presented here. Main products of the enzymatic reactions are shown in regular font size, while terpenoids detected as minor peaks are shown in a smaller size. Reactions are drawn based on data from in vitro enzymatic assays from [52,53,54,55,56].
