Comparative transcriptomic analysis and antioxidant defense mechanisms in clusterbean (Cyamopsis tetragonoloba (L.) Taub.) genotypes with contrasting drought tolerance.
Article in Functional & integrative genomics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
To understand drought tolerance mechanism(s) in clusterbean (Cyamopsis tetragonoloba), we conducted physiological, biochemical, and de novo comparative transcriptome analysis of drought-tolerant (RGC-1002) and drought-sensitive (RGC-1066) genotypes subjected to 30 days of drought stress. Relative water content (RWC) was maintained in tolerant genotype but was reduced in sensitive genotype. Leaf pigment concentrations were higher in tolerant genotype. Net photosynthesis was significantly decreased in sensitive genotype but insignificant reduction was found in tolerant genotype. Enzymatic antioxidant (GR, APX, DHAR) activities were enhanced in tolerant genotype, while there were insignificant changes in these enzymes in sensitive genotype. The ratios of antioxidant molecules (ASC/DHA and GSH/GSSG) were higher in tolerant genotype as compared to sensitive genotype. In sensitive genotype, 6625 differentially expressed genes (DEGs) were upregulated and 5365 genes were downregulated. In tolerant genotype, 5206 genes were upregulated and 2793 genes were downregulated. In tolerant genotype, transketolase family protein, phosphoenolpyruvate carboxylase 3, temperature-induced lipocalin, and cytochrome oxidase were highly upregulated. Moreover, according to Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, the drought tolerance may be attributed to upregulated starch and sucrose metabolism-related genes in tolerant genotype. Finally, quantitative real-time PCR confirmed the reproducibility of the RNA-seq data.
