6-Phosphogluconate dehydrogenase (PGD) allele phylogeny is incongruent with a recent origin of polyploidization in some North American Sphaeriidae (Mollusca, Bivalvia).

Molecular phylogenetics and evolution - 1 Oct 2002

Lee Taehwan, Foighil Diarmaid O

Abstract excerpt

Although polyploidization is rare among bivalve mollusks, recent cytogenetic studies have revealed a remarkable degree of genome amplification (up to 13n) in the freshwater bivalve family Sphaeriidae. We generated single-copy nuclear gene trees in order to test hypotheses addressing the evolutionary origins of sphaeriid genome duplication. Polyploid North American members of three cosmopolitan sphaeriid genera...
