Genome-wide identification of heterotrimeric G protein genes in castor (Ricinus communis L.) and expression patterns under salt stress.
Article in BMC genomics, 2024. 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
backgroundHeterotrimeric G proteins are crucial signaling molecules involved in cell signaling, plant development, and stress response. However, the genome-wide identification and analysis of G proteins in castor (Ricinus communis L.) have not been researched.
resultsIn this study, RcG-protein genes were identified using a sequence alignment method and analyzed by bioinformatics and expression analysis in response to salt stress. The results showed that a total of 9 G-protein family members were identified in the castor genome, which were classified into three subgroups, with the majority of RcG-proteins showing homology to soybean G-protein members. The promoter regions of all RcG-protein genes contained antioxidant response elements and ABA-responsive elements. Go enrichment analysis displayed that RcG-protein genes were involved in the G protein-coupled receptor signaling pathway, regulation of root development, and response to the bacterium. Real-time PCR showed varying responses of all RcG-protein genes to salt stress. RcGB1 was notably expressed in both roots and leaves under salt treatment, suggesting that it may be an essential gene associated with salt tolerance in the castor.
conclusionsThis study offers a theoretical framework for exploring G-protein function and presents potential genetic assets for improving crop resilience through genetic enhancement.
