Evolution of monoblepharidalean fungi based on complete mitochondrial genome sequences.

ABSTRACT: We have determined the complete mitochondrial DNA (mtDNA) sequences of three chytridiomycete fungi, Monoblepharella15, Harpochytrium94 and Harpochytrium105. Our phylogenetic analysis based on concatenated mitochondrial protein sequences confirms the placement of Mono blepharella15 together with Harpochytrium spp. and Hyaloraphidium curvatum within the taxonomic order Monoblepharidales, with overwhelming support. These four mtDNA sequences encode the standard fungal mitochondrial gene complement and, like certain other chytridiomycete fungi, encode a reduced complement of 7-9 tRNAs, some of which require 5'-tRNA editing to be functional. Highly conserved sequence elements were identified upstream of almost all protein-coding genes in the mtDNAs of Monoblepharella15 and both Harpochytrium sp
