Heavy-metal stress induced accumulation of chitinase isoforms in plants.
Article in Molecular biology reports, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 40 papers.
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.
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
Plant chitinases belong to so-called pathogenesis related proteins and have mostly been detected in plants exposed to phytopathogenic viruses, bacteria or fungi. A few studies revealed that they might also be involved in plant defence against heavy metals. This work was undertaken to monitor the accumulation of chitinases in a set of heavy-metal stressed plants and bring evidence on their involvement during this kind of stress. Roots of different plant species including Vicia faba cvs. Astar and Piestanský, Pisum sativum, Hordeum vulgare, Zea mays and Glycine max were exposed to different concentrations of lead (300 and 500 mg l(-1) Pb(2+)), cadmium (100 and 300 mg l(-1) Cd(2+)) and arsenic (50 and 100 mg l(-1) As(3+)). In each case, the toxicity effects were reflected in root growth retardation to 80-10% of control values. The most tolerant were beans, most sensitive was barley. Extracts from the most stressed roots were further assayed for chitinase activity upon separation on polyacrylamide gels. Our data showed that in each combination of genotype and metal ion there were 2-5 different chitinase isoforms significantly responsive to toxic environment when compared with water-treated controls. This confirms that chitinases are components of plant defence against higher concentrations of heavy metals. In addition, accumulation of some isoforms in response to one but not to other metal ions suggests that these enzymes might also be involved in a more (metal) specific mechanism in affected plants and their biological role is more complex than expected.
