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

Phosphoenolpyruvate carboxylase (PEPC) is distributed in plants and bacteria but is not found in fungi and animal cells. Important motifs for enzyme activity and structure are conserved in plant and bacterial PEPCs, with the exception of a phosphorylation domain present at the N terminus of all plant PEPCs reported so far, which is absent in the bacterial enzymes. Here, we describe a gene from Arabidopsis, stated as Atppc4, encoding a PEPC, which shows more similarity to Escherichia coli than to plant PEPCs. Interestingly, this enzyme lacks the phosphorylation domain, hence indicating that it is a bacterial-type PEPC. Three additional PEPC genes are present in Arabidopsis, stated as Atppc1, Atppc2, and Atppc3, encoding typical plant-type enzymes. As most plant PEPC genes, Atppc1, Atppc2, and Atppc3 are formed by 10 exons interrupted by nine introns. In contrast, Atppc4 gene has an unusual structure formed by 20 exons. A bacterial-type PEPC gene was also identified in rice (Oryza sativa), stated as Osppc-b, therefore showing the presence of this type of PEPC in monocots. The phylogenetic analysis suggests that both plant-type and bacterial-type PEPCs diverged early during the evolution of plants from a common ancestor, probably the PEPC from gamma-proteobacteria. The diversity of plant-type PEPCs in C3, C4, and Crassulacean acid metabolism plants is indicative of the evolutionary success of the regulation by phosphorylation of this enzyme. Although at a low level, the bacterial-type PEPC genes are expressed in Arabidopsis and rice.
