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

The phytoplankton of the world's oceans play an integral part in global carbon cycling and food webs by conversion of carbon dioxide into organic carbon. They accomplish this task through the action of the Calvin cycle enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). Here we have investigated the phylogenetic diversity in the form I rbcL locus in natural phytoplankton communities of the open ocean and representative clones of marine autotrophic picoplankton by mRNA or DNA amplification and sequencing of a 480 to 483 bp internal fragment of this gene. Five gene sequences were recovered from nucleic acids of natural phytoplankton communities of the Gulf of Mexico. The rbcL genes of two Prochlorococcus isolates and one Synechococcus strain (WH8007) were also sequenced. Sequences were aligned with the database of rbcL genes and subjected to both neighbor-joining and parsimony analyses. The five sequences from the natural phytoplankton community spanned nearly the entire diversity of characterized form I rbcL genes, with some sequences closely related to isolates such as Synechococcus and Prochlorococcus (forms IA and I) and prymnesiophyte algae (form ID), while other sequences were deeply rooted. Unexpectedly, the deep euphotic zone contained an organism that possesses a transcriptionally active rbcL gene closely related to that of a recently characterized manganese-oxidizing bacterium, suggesting that such chemoautotrophs may contribute to the diversity of carbon-fixing organisms in the marine euphotic zone.
