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

A chimeric gene composed of the coding sequence of the ble gene from Streptoalloteichus hindustanus fused to the 5' and 3' untranslated regions of the Chlamydomonas reinhardtii nuclear gene RBCS2 has been constructed. Introduction of this chimeric gene into the nuclear genome of C. reinhardtii by co-transformation with the ARG7 marker yields Arg+ transformants of which approximately 80% possess the ble gene. Of these co-transformants, approximately 3% display a phleomycin-resistant (PmR) phenotype. Western blot analysis using antibodies against the ble gene product confirms the presence of the protein in the PmR transformants and genetic analysis demonstrates the co-segregation of the ble gene with the phenotype in progeny arising from the mating of a PmR transformant to wild-type strains. Direct selection of PmR transformants was achieved by allowing an 18-h period for recovery and growth of transformed cells prior to selection. This work represents the first demonstration of stable expression and inheritance of a foreign gene in the nuclear genome of C. reinhardtii and provides a useful dominant marker for nuclear transformation.
