Mapping of mitochondrial mRNA termini in Arabidopsis thaliana: t-elements contribute to 5' and 3' end formation.

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
With CR-RT-PCR as primary approach we mapped the 5' and 3' transcript ends of all mitochondrial protein-coding genes in Arabidopsis thaliana. Almost all transcripts analyzed have single major 3' termini, while multiple 5' ends were found for several genes. Some of the identified 5' ends map within promoter motifs suggesting these ends to be derived from transcription initiation while the majority of the 5' termini seems to be generated post-transcriptionally. Assignment of the extremities of 5' leader RNAs revealed clear evidence for an endonucleolytic generation of the major cox1 and atp9 5' mRNA ends. tRNA-like structures, so-called t-elements, are associated either with 5' or with 3' termini of several mRNAs. These secondary structures most likely act as cis-signals for endonucleolytic cleavages by RNase Z and/or RNase P. Since no conserved sequence motif is evident at post-transcriptionally derived ends, we suggest t-elements, stem-loops and probably complex higher order structures as cis-elements for processing. This analysis provides novel insights into 5' and 3' end formation of mRNAs. In addition, the complete transcript map is a substantial and important basis for future studies of gene expression in mitochondria of higher plants.
