In plants and animals, gene expression can be down-regulated at the posttranscriptional level by microRNAs (miRNAs), a class of small endogenous RNA. Comparative analysis of miRNA content across species indicates continuous birth and death of these loci in the course of evolution. However, little is known about the microevolutionary dynamics of these genetic elements, especially in plants. In this article we examine polymorphism at two miRNA-encoding loci in Arabidopsis thaliana, miR856 and… CONTINUE READING
