Identification of two additional members of the tRNA isopentenyltransferase family in Physcomitrella patens.
Article in Plant molecular biology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
The Physcomitrella patens genome has seven genes apparently coding for the isopentenyltransferase type of tRNA-modifying enzyme, while other organisms have one or two. The predicted sequences have parts that differ significantly from other isopentenyltransferases. Only one of the seven (PpIPT1) has earlier been shown to be expressed. We now report expression of two more, PpIPT4 and PpIPT5. The cloned genes were able to functionally complement a yeast mutant lacking tRNA isopentenyltransferase. Sequencing showed they are related to the earlier studied PpIPT1. The sequences of the three differ mainly from each other in a tRNA-binding area and the 5'-end subcellular targeting motif area. This indicates that, after arising through gene duplication, they have evolved to enable partly different functions.
