Widespread signatures of selection for secreted peptidases in a fungal plant pathogen.

ABSTRACT:

Background

Fungal plant pathogens secrete a large arsenal of hydrolytic enzymes during the course of infection, including peptidases. Secreted peptidases have been extensively studied for their role as effectors. In this study, we combined transcriptomics, comparative genomics and evolutionary analyses to investigate all 39 secreted peptidases in the fungal wheat pathogen Zymoseptoria tritici and its close relatives Z. pseudotritici and Z. ardabiliae.

Results

RNA-seq data revealed that a majority of the secreted peptidases displayed differential transcription during the course of Z. tritici infection, indicative of specialization for different stages in the life cycle. Evolutionary analyses detected widespread evidence of adaptive evolution acting on at least 28 of the pepti
