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

Rhodobacter capsulatus fixes CO2 via the Calvin reductive pentose phosphate pathway and, like some other nonsulfur purple bacteria, is known to synthesize two distinct structural forms of ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO). Cosmid clones that hybridized to form I (cbbLcbbS) and form II (cbbM) RubisCO gene probes were isolated from a genomic library of R. capsulatus strain SB1003. Southern blotting and hybridization analysis with gene-specific probes derived from Rhodobacter sphaeroides revealed that R. capsulatus cbbM is clustered with genes encoding other enzymes of the Calvin cycle, including fructose 1,6/sedoheptulose 1,7-bisphosphatase (cbbF), phosphoribulokinase (cbbP), transketolase (cbbT), glyceraldehyde-3-phosphate dehydrogenase (cbbG), and fructose 1,6-bisphosphate aldolase (cbbA), as well as a gene (cbbR) encoding a divergently transcribed LysR-type regulatory protein. Surprisingly, a cosmid clone containing the R. capsulatus form I RubisCO genes (cbbL and cbbS) failed to hybridize to the other cbb structural gene probes, unlike the situation with the closely related organism R. sphaeroides. The form I and form II RubisCO genes were cloned into pUC-derived vectors and were expressed in Escherichia coli to yield active recombinant enzyme in each case. Complementation of a RubisCO-deletion strain of R. sphaeroides to photosynthetic growth by R. capsulatus cbbLcbbS or cbbM was achieved using the broad host-range vector, pRK415, and R. sphaeroides expression vector pRPS-1.
