Proteomics analysis identified a DRT protein involved in arsenic resistance in Populus.
Article in Plant cell reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
key messageA DRT protein was identified and proved to be involved in the poplar arsenic resistance through comparative proteomics analysis between arsenic sensitive and resistant cultivars. Arsenic pollution in soil has been a serious problem all over the world. It is very important to dissect plants arsenic stress-response mechanisms in phytoremediation. In this study, arsenate-tolerant Populus deltoides cv. 'zhonglin 2025' and arsenate-sensitive Populus × euramericana cv. 'I-45/51' were screened from 10 poplar varieties. Systematic comparisons between these two cultivars demonstrated that 'zhonglin 2025' exhibited slighter morphological and structural injury, lower ROS and MDA accumulation, and higher photosynthesis and ROS scavenging ability under arsenate stress, compared with 'I-45/51'. Through comparative proteomics analysis, we detected that most of the identified arsenate-responsive proteins were stress and defense related. Among these proteins, PdDRT102 was found to be only highly induced in 'zhonglin 2025' under arsenate stress. Heterologous over-expression of PdDRT102 in Arabidopsis conferred to enhanced tolerance to arsenate and sodium chloride. PdDRT102 localizes to the plasma membrane and the nucleus in Arabidopsis. Interestingly, the remarkably increased fluorescence protein signals in the nucleus were found during arsenate stress. Together, these results not only provided an overall understanding on poplar response to arsenate stress, but also revealed that DRT102 protein might involve in protecting poplar against this stress.
