Comparative analysis of the MIR319a microRNA locus in Arabidopsis and related Brassicaceae

Warthmann, Norman; Das, Sandip; Lanz, Christa; Weigel, Detlef

Description

MicroRNAs (miRNAs) are important regulators of gene expression in multicellular organisms. Yet, little is known about their molecular evolution. The 20- to 22-nt long miRNAs are processed in plants from foldbacks that are a few hundred base pairs in size. Often, these foldbacks are embedded in much larger precursor transcripts. To investigate functional constraints on sequence evolution of miRNA precursor genes, we have studied sequence variation in the precursor of miR319a, MIR319a, between...[Show more]
