Identification of the Valine-Glutamine gene family in Chenopodium quinoa Willd and analysis of its expression pattern and subcellular localization under drought stress.
Article in BMC genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundChenopodium quinoa Willd (Quinoa) is highly tolerant to drought, cold, and salt stress. Gene editing technology development, and research on quinoa's drought resistance have attracted much attention. The transcriptional cofactor VQ plays an important role in the drought response in plants, but its role in quinoa has not been reported.
resultsBioinformatics identified 23 members of the quinoa VQ gene family, mainly located in the nucleus and unevenly distributed on 10 chromosomes. Gene structure and phylogenetic analysis indicated that the VQ genes were closely related and highly conserved, forming three subfamilies. The cis-acting elements of the promoter reveal its involvement in the response to light and hormonal stress. qRT-PCR analysis showed that all VQ genes were differentially expressed under drought stress, among which CqVQ13 was significantly up-regulated, and subcellular localization indicated that it was localized to the nucleus.
conclusionThis study conducted a systematic bioinformatics analysis of the basic physicochemical properties and chromosome localization of 23 members of the CqVQ gene family. Combined with transcriptome gene expression profiling and qRT-PCR, we found that CqVQ13 was significantly up-regulated under drought stress and localized in the nucleus. This discovery provides an important candidate gene for drought response studies in quinoa and lays the foundation for further exploration of the molecular mechanisms of the VQ gene family in response to drought stress.
