A short time ago, I mentioned this article. This study was the product of a collaboration between five laboratories – two plant poly(A) labs, a seed biology lab, and two bioinformatics groups. As the abstract indicated, this paper describes the results of a characterization of polyadenylation in plants using so-called Next Generation DNA sequencing technology; as such it is an addition to other recent studies, albeit the first (to my knowledge) that deals with plants.
I’m more than happy to answer questions about the paper in the comments. What I will do in the essay is described one of the more perplexing findings, and “amend” the PNAS paper with a few illustrations that we couldn’t include in the paper (even the online Supplemental Files – we maxed out the print and SI page limits).
