Venn diagrams showing numbers of differentially expressed genes in oak after inoculation with mycorrhizal fungi. Differential expression thresholds of RNA sequencing data were at least 2-fold difference to control (no fungus) and a Benjamini-Hochberg adjusted P < 0.01. Numbers in brackets indicate the total number of differentially expressed genes under each treatment. (a) colonized oak roots, (b) non-colonized oak roots, and (c) leaves after inoculation of P. microcarpus, P. involutus, L. bicolor and S. vermifera
