Background: The analysis of synonymous and nonsynonymous rates of DNA
change can help in the choice among competing explanations for rate variation, such
as differences in constraint, mutation rate, or the strength of genetic drift.
Nonphotosynthetic plants of the Orobanchaceae have increased rates of DNA change. In
this study 38 taxa of ... read moreOrobanchaceae and relatives were used and 3 plastid genes were
sequenced for each taxon.
