Population Genetic Considerations Regarding Evidence for Biased Mutation Rates in Arabidopsis thaliana.

Abstract excerpt

It has recently been proposed that lower mutation rates in gene bodies compared with upstream and downstream sequences in Arabidopsis thaliana are the result of an "adaptive" modification of the rate of beneficial and deleterious mutations in these functional regions. This claim was based both on analyses of mutation accumulation lines and on population genomics data. Here, we show that several questionable...
