Involvement of phosphate supplies in different transcriptional regulation pathway of Oryza sativa L.'s antioxidative system in response to arsenite and cadmium stress.
Article in Ecotoxicology (London, England), 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The roles of different concentrations of arsenite (As(III)) and cadmium (Cd) (0, 25 and 50 μM) in the absence and presence (1.7 mM) of phosphate (P) in tolerance and antioxidant genes expression in Oryza sativa L. were investigated. The growth parameters, metal accumulation, lipid peroxidation and soluble protein and 17 genes involved in metal accumulation and oxidative stress were measured. In our results, Lsi6 (OsNIP2;2) could play an important role in As(III) accumulation of shoots and roots in P supply (+P) and deficiency (-P) plant, while OsNRAMP5 was attributed to the part of As(III) uptake though roots under -P condition. Both of Lsi6 and OsNRAMP5 could involve Cd uptake of roots in +P plant. OsNRAMP1 was a main transporter for As(III) and Cd uptake in roots of -P plant. However, +P increased the soluble protein contents and reduced the lipid peroxidation under As(III) or Cd exposures. In As(III) exposed rice seedlings, SOD, CAT, POD, GPX, AsA-GSH cycle and GSH metabolism process were provoked to eliminate ROS induced by As(III), especially under -P condition. In Cd exposed rice seedlings, AsA-GSH cycle and GSH metabolism process played a main role in the detoxification process of plant cells, and +P could promote enzyme system activity. Furthermore, +P improve the tolerance ability of plants to tolerant 50 μM As(III) and Cd exposures compared to P deficiency.
