Genome-wide dynamics of alternative polyadenylation in rice.
Alternative polyadenylation (APA), in which a transcript uses one of the poly(A) sites to define its 3'-end, is a common regulatory mechanism in eukaryotic gene expression. However, the potential of APA in determining crop agronomic traits remains elusive. This study systematically tallied poly(A) sites of 14 different rice tissues and developmental stages using the poly(A) tag sequencing (PAT-...
متن کاملGenome-wide mapping of polyadenylation sites in fission yeast reveals widespread alternative polyadenylation
Regulatory elements in the 3' untranslated regions (UTRs) of eukaryotic mRNAs influence mRNA localization, translation, and stability. 3'-UTR length is determined by the location at which mRNAs are cleaved and polyadenylated. The use of alternative polyadenylation sites is common, and can be regulated in different situations. I present a new method to identify cleavage and polyadenylation sites...
متن کاملGenome-wide landscape of polyadenylation in Arabidopsis provides evidence for extensive alternative polyadenylation.
Alternative polyadenylation (APA) has been shown to play an important role in gene expression regulation in animals and plants. However, the extent of sense and antisense APA at the genome level is not known. We developed a deep-sequencing protocol that queries the junctions of 3'UTR and poly(A) tails and confidently maps the poly(A) tags to the annotated genome. The results of this mapping sho...
متن کاملGenome-wide alternative polyadenylation in animals: insights from high-throughput technologies.
Alternative polyadenylation (APA) plays an important role in gene expression by affecting mRNA stability, translation, and translocation in cells. However, genome-wide APA events have only recently been subjected to more systematic analysis with newly developed high-throughput methods. In this review, we focus on the recent technological development of APA analyses on a genome-wide scale, as we...
متن کاملGenome-wide identification and predictive modeling of tissue-specific alternative polyadenylation
MOTIVATION Pre-mRNA cleavage and polyadenylation are essential steps for 3'-end maturation and subsequent stability and degradation of mRNAs. This process is highly controlled by cis-regulatory elements surrounding the cleavage/polyadenylation sites (polyA sites), which are frequently constrained by sequence content and position. More than 50% of human transcripts have multiple functional polyA...
