Psychrotolerant antifungal Streptomyces isolated from Tawang, India and the shift in chitinase gene family.
Article in Extremophiles : life under extreme conditions, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
A total of 210 Streptomyces were isolated from the soil samples of Tawang, India where temperature varied from 5 °C during daytime to -2 °C during the night. Based on antifungal activity, a total of 33 strains, putatively Streptomyces spp., were selected. Optimal growth temperature for the 33 strains was 16 °C, with growth occurring down to 6 °C but not above 30 °C. Phylogenetic analysis based on 16S rDNA sequences revealed the taxonomic affiliation of the 33 strains as species of Streptomyces. To examine the relatedness of the chitinase genes from six strong antifungal Streptomyces strains, a phylogenetic tree was constructed using the catalytic domain nucleotide sequences and resulted in seven distinct monophyletic groups. A quantitative PCR study for chitinase expressing ability revealed that of the six antifungal strains tested, the strain Streptomyces roseochromogenus TSR12 was the most active producer of family 18 chitinase genes. Streptomyces strains with enhanced inhibitory potential usually encode a family 19 chitinase gene; however, our present study did not show expression of this family in the six strains tested.
