Fig. 1: Transcriptome analysis of the BCA P. terrestris during dual and tritrophic interaction with the host M. domestica in the absence and in the presence of fungus P. expansum.

a Principal component analysis of the samples subjected to RNA analysis. b Venn diagram showing common and unique sets of upregulated genes related to P. terrestris analyses; in blue are the upregulated P. terrestris DEGs during dual interaction with the host M. domestica, while in yellow are the upregulated P. terrestris DEGs during tritrophic interaction with the fungus P. expansum and with the host M. domestica; in light brown DEGs in common between the two aforementioned conditions. c Gene ontology (GO) enrichment analysis of the P. terrestris DEGs carried out according to three groups depicted in the Venn Diagram reported in (b). d KEGG analysis of P. terrestris DEGs of the common group (624 DEGs).
