Abstract

We sequenced and annotated the complete mitogenomes of 13 geographically diverse strains of the important plant pathogen F. graminearum sensu stricto (s.s.). We found that presence-absence variation of four group I introns and two homing endonuclease genes (hegs) primarily determined the mitogenome length differences among the strains analyzed. Three group I introns (cox2 intron 2, cob intron 1 and cox1 intron 13) and the heg encoded by cob intron 4 were irregularly distributed among strains of F. graminearum s. s., whereas cox2 intron 3 and heg located within cox1 intron 9 were unique to a single strain. Nearly identical intron patterns were found between some F. graminearum s.s. strains and the F. culmorum strain, but proved more varied among the other F. graminearum s.s. strains. Furthermore, we found that all irregularly distributed introns and hegs showed evidence of putative horizontal transfer. The patterns of intron/hegs distribution did not correlate to the geographic origin of the strains. Phylogenetic analysis based on whole mitogenome sequence data showed partial correlation between tree topology and origin of the strains analyzed. The results of the studies presented in this paper provide new insight into intraspecific mitogenome variation of F. graminearum s.s.
