Putative secondary structures of tRNA genes identified in the mitogenomes of six Diaporthe species. The 23 tRNAs in green fonts represent tRNAs shared by the six Diaporthe species, while the tRNAs in blue font represent in all Diaporthe species except Diaporthe sp. ZM41-5, the tRNA in orange font represents tRNA only in D. sojae VNIIKR SE Dps12, and the tRNA in purple font represents tRNA only in D. eres ZM79-3. Besides, residues conserved across the six mitogenomes are shown in green, while variable sites are shown in red.
