Integrated genome and transcriptome analysis reveals pathogenic mechanisms of Calonectria eucalypti in Eucalyptus leaf blight.

ABSTRACT:

Background

Calonectria eucalypti is a destructive fungal pathogen causing Eucalyptus leaf blight in China and Indonesia. Despite its ecological and economic impact, the molecular mechanisms underlying its pathogenicity remain largely unexplored.

Results

We assembled a high-quality 62.1 Mb genome of C. eucalypti comprising 19 contigs and 13,112 predicted genes, including 1,006 carbohydrate-active enzymes (CAZymes), 351 candidate effectors, and 90 secondary metabolite biosynthetic gene clusters (SMGCs). Comparative genomics revealed 60 expanded gene families and eight species-specific clusters in C. eucalypti, predominantly enriched in virulence-associated functions such as transferase activity, sporulation, and host adhesion.
