1 · What the graph read from it

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.

2 · The registry

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

All tRNA(His) possess an essential extra G(-1) guanosine residue at their 5' end. In eukaryotes after standard processing by RNase P, G(-1) is added by a tRNA(His) guanylyl transferase. In prokaryotes, G(-1) is genome-encoded and retained during maturation. In plant mitochondria, although trnH genes possess a G(-1) we find here that both maturation pathways can be used. Indeed, tRNA(His) with or without a G(-1) are found in a plant mitochondrial tRNA fraction. Furthermore, a recombinant Arabidopsis mitochondrial RNase P can cleave tRNA(His) precursors at both positions G(+1) and G(-1). The G(-1) is essential for recognition by plant mitochondrial histidyl-tRNA synthetase. Whether, as shown in prokaryotes and eukaryotes, the presence of uncharged tRNA(His) without G(-1) has a function or not in plant mitochondrial gene regulation is an open question. We find that when a mutated version of a plant mitochondrial trnH gene containing no encoded extra G is introduced and expressed into isolated potato mitochondria, mature tRNA(His) with a G(-1) are recovered. This shows that a previously unreported tRNA(His) guanylyltransferase activity is present in plant mitochondria.
