The mitochondrial genome of and comparison with other fungi causing Dutch elm disease.

The mitochondrial genome of , a species endemic to the Western Himalayas and one of the fungi that cause Dutch elm disease, has been sequenced and characterized. The mitochondrial genome was compared with other available genomes for members of the Ophiostomatales, including other agents of Dutch elm disease (, subspecies , and subspecies ), and it was observed that gene synteny is highly conserved, and variability among members of the fungi that cause Dutch-elm disease is primarily due to the number of intron insertions. Among the fungi that cause Dutch elm disease that we examined, has the largest mitochondrial genomes (ranging from 94 934 to 111 712 bp), owing to the expansion of the number of introns.
