Selective constraints on intron evolution in Drosophila.

Abstract excerpt

Intron sizes show an asymmetrical distribution in a number of organisms, with a large number of "short" introns clustered around a minimal intron length and a much broader distribution of longer introns. In Drosophila melanogaster, the short intron class is centered around 61 bp. The narrow length distribution suggests that natural selection may play a role in maintaining intron size. A comparison of 15...
