Mitogenome-wide comparison and phylogeny reveal group I intron dynamics and intraspecific diversification within the phytopathogen Corynespora cassiicola.

ABSTRACT: Corynespora cassiicola, the causal agent of an extensive range of plant diseases worldwide, is a momentous fungus with diverse lifestyles and rich in intraspecies variations. In the present study, a total of 56 mitochondrial genomes of C. cassiicola were assembled (except two available online) and analyzed, of which 16 mitogenomes were newly sequenced here. All these circular mitochondrial DNA (mtDNA) molecules, ranging from 39,223 bp to 45,786 bp in length, comprised the same set of 13 core protein-coding genes (PCGs), two rRNAs and 27 tRNAs arranged in identical order. Across the above conserved genes, nad3 had the largest genetic distance between different isolates and was possibly subjected to positive selection pressure. Comparative mitogenomic analysis indicated
