Overexpression of CrCOMT from Carex rigescens increases salt stress and modulates melatonin synthesis in Arabidopsis thaliana.
Article in Plant cell reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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 messageCrCOMT, a COMT gene in Carex rigescens, was verified to enhance salt stress tolerance in transgenic Arabidopsis. High salinity severely restricts plant growth and development while melatonin can alleviate salt damage. Caffeic acid O-methyltransferase (COMT) plays an important role in regulating plant growth, development, and stress responses. COMT could also participate in melatonin biosynthesis. The objective of this study was to identify CrCOMT from Carex rigescens (Franch.) V. Krecz, a stress-tolerant grass species with a widespread distribution in north China, and to determine its physiological functions and regulatory mechanisms that impart tolerance to salt stress. The results showed that the transcription of CrCOMT exhibited different expression patterns under salt, drought, and ABA treatments. Transgenic Arabidopsis with the overexpression of CrCOMT exhibited improved growth and physiological performance under salt stress, such as higher lateral root numbers, proline level, and chlorophyll content, than in the wild type (WT). Overexpression of CrCOMT also increased dehydration tolerance in Arabidopsis. The transcription of salt response genes was more highly activated in transgenic plants than in the WT under salt stress conditions. In addition, the melatonin content in transgenic plants was higher than that in the WT after stress treatment. Taken together, our results indicated that CrCOMT may positively regulate stress responses and melatonin synthesis under salt stress.
