Tomato putative fatty-acid desaturases (FADs) involved in the biosynthesis of fatty acids in leaves and roots. (A). 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. (B). Biosynthetic pathway leading to oxylipins (left) and falcarindiol (right). Linoleic acid is used in the biosynthesis of jasmonic acid and other oxylipins, as well as the production of highly modified fatty acids (polyacetylenes). Proposed chemical structures, gene function and biosynthetic pathway are based on the work of [51].
