Multipotential rhizobacteria simultaneously mitigate salinity stress and improve growth and physiological traits in black cumin (Nigella sativa L.).
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Soil salinity impairs the growth, development, and the yields of the crops and contribute to increased agriculture productivity. Plant growth-promoting rhizobacteria (PGPR) help plant growth and mitigate soil salinity. The present study aimed to isolate multifarious rhizobacteria to simultaneously mitigate salinity stress and improve growth and physiological traits in black cumin. The study revealed the effects of Bacillus subtilis IGPEB 1, Bacillus altitudinis IGPEB 8, Bacillus endophyticus IGPEB 33, and Pseudomonas koreensis IGPEB 17 on the growth and physiological properties of Nigella sativa L. under salt stress. The results revealed that B. altitudinis IGPEB 8, B. endophyticus IGPEB 33, and B. altitudinis IGPEB 8 significantly increased the shoot length by 20.96% and 26.73% and total root length by 73.15%, respectively. B. endophyticus IGPEB 33 (T4) significantly enhanced total root length by 103.66%, projected area by 36.67%, and root surface area by 50.78%, respectively. Application of B. altitudinis IGPEB 8 (T3) and B. endophyticus IGPEB 33 (T4) enhanced total chlorophyll content by 73.36% and 85.51%, chlorophyll a by 74.46% and 80.00%, chlorophyll b by 66.66% and total chlorophyll by 45.71% and carotenoid contents by 55.55% and 79.62%, respectively, the antioxidant capacity, antioxidant enzymes' activities and relative water content of leaves by 8.25% and 9.07% compared to the control. The consortium of B. altitudinis IGPEB 8 and B. endophyticus IGPEB 33 positively influences physiological properties in Nigella sativa L. under salt stress.
