Posttranscriptional control is important in the overall regulation of gene expression in plants. Such control may be manifested through numerous mechanisms such as RNA turnover, transport and/or sequestration, and differential translation. Many of these processes involve, in some manner, the 3′-untranslated region (or UTR) and polyadenylation signal of the gene. It follows that the nature of the 3′-UTR, and choice of polyadenylation site in genes with multiple sites, may play a role in the expression of a gene, with important physiological consequences. Consequently, the processes involved in alternative and regulated RNA polyadenylation, as well as generating 3′-UTR and 3′-end heterogeneity, are of considerable importance in terms of defining the expression profile of the plant genome.
