Flanking vs . coding region diversity in C. nigra and E. orbicularis . πS: average nucleotide diversity at synonymous sites; π5: average nucleotide diversity at 5′-UTR sites; π3: average nucleotide diversity at 3′-UTR sites. Very similar results were obtained when we only analyzed predicted cDNAs for which both coding sequence and 3′ UTR sequence were available, and when we restricted the analysis to the 500 first bases of the 3′ UTR regions.
