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 characterization of a non-photosynthetic isoform of NADP-malic enzyme (NADP-ME) from maize roots, which represents nearly 7% of the total soluble protein of this tissue, was performed. The molecular properties of the purified protein, as well as the kinetic parameters determined, indicate that the NADP-ME isoform present in maize roots differs from the photosynthetic enzyme implicated in the C4 cycle, but is similar, or identical, to the enzyme previously characterized from etiolated maize leaves (Maurino, Drincovich and Andreo, Biochem. Mol. Biol. Int. 38 (1996) 239-250). A full-length ORF encoding a plastidic NADP-ME (almost identical to the maize root NADP-ME, GenBank accession number U39958) was cloned from a root cDNA library as well as isolated by reverse transcription (RT)-PCR using green leaves mRNA as template. These results indicate that root NADP-ME does not constitute a root-specific isoform, but represents a protein with a constitutive pattern of expression in plastids of the C4 plant maize. The amount of NADP-ME measured by activity, western and northern blot was modified when different stress conditions (including treatments with cellulase, fungal elicitors, jasmonate and hypoxic treatment) were applied to maize roots, indicating that the enzyme from maize roots is under transcriptional or post-transcriptional regulation by effectors related to plant defence responses. It is deduced that the induction of housekeeping genes, like non-photosynthetic NADP-ME, whose constitutive role may be the provision of reductive power in non-photosynthetic plastids, is likely to accompany the defence response.
