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

L- Aspartate-alpha-decarboxylase catalyzes the decarboxylation of L -aspartate to generate Beta-alanine and carbon dioxide. This is an unusual pyruvoyl-dependent enzyme unique to prokaryotes that undergoes limited self-processing. The Escherichia coli pan D gene encoding L- aspartate-alpha-decarboxylase was expressed under a constitutive promoter in transgenic tobacco. Transgene expression was verified by assays based on RNA blots, immunoblots and enzyme activity in vitro. The pan D lines had increased levels of leaf Beta-alanine (1.2- to 4-fold), pantothenate (3.2- to 4.1-fold) and total free amino acids (up to 3.7-fold) compared to wild-type and vector controls. Growth of homozygous lines expressing E. coli L- aspartate-alpha-decarboxylase was less affected than that of the control lines when the plants were stressed for 1 week at 35 degrees C. When transferred from 35 to 30 degrees C for 3 weeks, the Pan D transgenic lines recovered significantly (P <or= 0.001) better than the controls: Pan D lines had on an average 54% and 84% greater fresh and dry weights respectively, compared to the controls. Homozygous lines expressing E. coli L- aspartate-alpha-decarboxylase had significantly greater thermotolerance (P<or=0.05) during germination. At 42 degrees C, 95% of two T3 Pan D transgenic line seeds germinated after 12 days compared to 73% for the wild-type seeds. Our results indicated that E. coli L-aspartate-alpha-decarboxylase was correctly processed and active in the transgenic eukaryotic host and its expression resulted in increased thermotolerance in tobacco.
