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

Taraxacum brevicorniculatum is known to produce high quality rubber. The biosynthesis of rubber is dependent on isopentenyl pyrophosphate (IPP) precursors derived from the mevalonate (MVA) pathway. The cDNA sequences of seven MVA pathway genes from latex of T. brevicorniculatum were isolated, including three cDNA sequences encoding for 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductases (TbHMGR1-3). Expression analyses indicate an important role of TbHMGR1 as well as for the HMG-CoA synthase (TbHMGS), the diphosphomevalonate decarboxylase and the mevalonate kinase in the provision of precursors for rubber biosynthesis. The amino acid sequences of the TbHMGRs show the typical motifs described for plant HMGRs such as two transmembrane domains and a catalytic domain containing two HMG-CoA and two NADP(H) binding sites. The functionality of the HMGRs was demonstrated by complementation assay using an IPP auxotroph mutant of Escherichia coli. Furthermore, the transient expression of the catalytic domains of TbHMGR1 and TbHMGR2 in Nicotiana benthamiana resulted in a strong accumulation of sterol precursors, one of the major groups of pathway end-products.
