A pollen-, ovule-, and early embryo-specific poly(A) binding protein from Arabidopsis complements essential functions in yeast.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Poly(A) tails of eukaryotic mRNAs serve as targets for regulatory proteins affecting mRNA stability and translation. Differential mRNA polyadenylation and deadenylation during gametogenesis and early development are now widely recognized as mechanisms of translational regulation in animals, but they have not been observed in plants. Here, we report that the expression of the PAB5 gene encoding one of the poly(A) binding proteins (PABPs) in Arabidopsis is restricted to pollen and ovule development and early embryogenesis. Furthermore, PAB5 is capable of rescuing a PABP-deficient yeast strain by partially restoring both poly(A) shortening and translational initiation functions of PABP. However, PAB5 did not restore the linkage of deadenylation and decapping, thus demonstrating that this function of PABP is not essential for viability. Also, like endogenous PABP, PAB5 expressed in yeast demonstrated genetic interaction with a recently characterized yeast protein SIS1, which is also involved in translational initiation. We propose that PAB5 encodes a post-transcriptional regulatory factor acting through molecular mechanisms similar to those reported for yeast PABP. This factor may have evolved further to post-transcriptionally regulate plant sexual reproduction and early development.
