Comparative genomic analysis reveals contraction of gene families with putative roles in pathogenesis in the fungal boxwood pathogens Calonectria henricotiae and C. pseudonaviculata.

ABSTRACT:

Background

Boxwood blight disease caused by Calonectria henricotiae and C. pseudonaviculata is of ecological and economic significance in cultivated and native ecosystems worldwide. Prior research has focused on understanding the population genetic and genomic diversity of C. henricotiae and C. pseudonaviculata, but gene family evolution in the context of host adaptation, plant pathogenesis, and trophic lifestyle is poorly understood. This study applied bioinformatic and phylogenetic methods to examine gene family evolution in C. henricotiae, C. pseudonaviculata and 22 related fungi in the Nectriaceae that vary in pathogenic and saprobic (apathogenic) lifestyles.

Results

A total of 19,750 gene families were identified in the 24 genomes, of which 422 were rapidly evolving. Am
