Differential proteomics in response to low temperature diazotrophy of Himalayan psychrophilic nitrogen fixing Pseudomonas migulae S10724 strain.
Article in Current microbiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Himalayas are considered as a reservoir of diversified and dynamic gene pool. This study describes the response of a Himalayan psychrophilic diazotroph to low temperature diazotrophy. Seven cold adaptive N2 fixing bacteria were isolated and identified as Bacillus sp., Arthrobacter sp., Rhodococcus sp., Pseudomonas sp., etc. In order to examine the physiological response to low temperature diazotrophy, differential proteomic analysis of Pseudomonas migulae S10724 strain was carried out using two dimensional electrophoresis and MALDI-TOF-MS. Functional assessment of 66 differentially expressed proteins revealed several mechanisms thought to be involved in low temperature adaptation and nitrogen fixation, including general stress adaptation, protein and nucleic acid synthesis, energy metabolism, cell growth/maintenance, etc. Major fraction of the upregulated proteins was stress proteins, while majority of the downregulated proteins were related to cell division. Furthermore, MALDI-TOF-MS-based identification of randomly selected peptides encountered two exclusively expressed proteins: NifU family SUF system FeS assembly protein and membrane protein, suppressor for copper-sensitivity B precursor which might have a crucial role at low temperature nitrogen fixation. To the best of our knowledge, this is the first report of the isolation and differential proteomic analysis of psychrophilic diazotroph from Himalayan high altitude rhizospheric soil.
