For each species, the respective sex determination system and the presence of DUI is specified (DUI occurrence is uncertain at present in N. margaritacea). For each mtDNA, GenBank accession number and respective reference are indicated. mtDNA type F or M is indicated for DUI species only; N. margaritacea mtDNA here considered might be an F if DUI will be confirmed in this species. H type is indicated only for unionid species who secondarily lost DUI and became hermaphroditic. References for each sequence are indicated with superscripts after the accession numbers: asterisks (*) indicate sequences obtained in this study; numbers published data; and letters unpublished data (aJiang W.P., Li J.L., Zheng R.L.; bZheng R.L., Li J.L.; cLin Q.H., Zeng L.G., Sheng J.Q., Wang J.H., Hong Y.J.; dOkazaki M., Ueshima R.; eSoroka M., Burzynsky A.; fDreyer H., Steyner G.).
