Multiple reversals of strand asymmetry in molluscs mitochondrial genomes, and consequences for phylogenetic inferences

摘要

Graphical abstractDisplay OmittedHighlights?The strand asymmetry of mtDNA was compared across 140 mollusc species.?All bivalves and most gastropods arecharacterized by a reversal of strand bias.?The differences in the patterns of strand asymmetry influenced the amino acid composition.?NTE model didn’t deal with the question of phylogenetic relationships for major molluscs lineages.?NTE model are not appropriate for molluscs mt genome data.AbstractStrand asymmetry in nucleotide composition is a remarkable fe
