Induced genetic and chemical changes in medicinally important plant Catharanthus roseus (L.) G. Don: cold plasma and phytohormones.
Article in Molecular biology reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundCatharanthus roseus (L.) G. Donis a medicinal plant species belonging to the Apocynaceae family, which produces vinblastine and vincristine along with 100 other monoterpenoid indole alkaloids. The process of biosynthesis of C. roseus alkaloids is complex, in which many genes, enzymes, and regulators are involved. Induced mutations may be considered as a potential source for producing a higher amount of vinblastine and vincristine in this plant species. Therefore, the objective of the present study was to examine the effects of different treatments utilized on the induced genetic changes in C. roseus plants and enzyme activities. METHODS AND
resultsSpermine, jasmonic acid, methyjasmonate, putrescine, and cold plasma treatments were used for seed treatments. Different molecular markers, namely inter simple sequence repeat, inter retrotransposon amplified polymorphism, and retrotransposon microsatellite amplified polymorphism were employed to reveal the induced genetic changes. Antioxidant enzyme activities were also studied. The treated plants showed genetic variability and a significant increase in antioxidant enzyme activity compared to the control plants. The putrescine treatment resulted in the highest level of activity in superoxidase. A significant positive correlation occurred between the molecular markers data and antioxidant enzyme activities in treated plants.
conclusionOur data revealed that the different phytohormones and cold plasma treatments could induce both genetic and chemical content changes in C. roseus plants.
