Comparative transcriptomics analysis of compatible wild type and incompatible Δ

Epichloë festucae fungi form bioprotective endophytic symbioses with perennial ryegrass. Although this interaction is economically important, relatively little is known about the molecular processes and regulatory genes that are involved in establishing a compatible symbiosis. The present study utilised next-generation sequencing to investigate the genes required for establishing a compatible symbiotic interaction between E. festucae and perennial ryegrass. A comparative transcriptomics study, comparing the compatible symbiotic interaction of E. festucae/perennial ryegrass with the incompatible interaction of a ΔlaeA mutant strain of E.festucae/perennial ryegrass, was performed two weeks after inoculation. Differentially expressed genes were identified and classified according to gene ontology and functional annotation analyses. The raw data of this study have been deposited at SRA database with the BioProject ID PRJNA513830.
