Genome-wide identification and comparative evolution of 14-3-3 gene family members in five Brassicaceae species.

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
backgroundThe 14-3-3 proteins are highly conserved regulatory eukaryotic proteins, which are crucial in growth, development, and stress responses. However, systematic characterization of the 14-3-3 gene family in Brassicaceae species and their evolutionary relationships have not been comprehensively reported.
resultsThis study conducted genome-wide identification, structural characteristics, and comparative evolutionary analysis of 14-3-3 gene family members in Arabidopsis thaliana, A. lyrata, A. pumila, Camelina sativa, and Brassica oleracea using comparative genomics. Overall, a total of 108 14-3-3 genes, which were phylogenetically classified into ε and non-ε groups were identified in the five species, with the non-ε members exhibiting more similar exon-intron structures and conserved motif patterns. Collinearity analysis revealed that the Brassicaceae 14-3-3 gene family members underwent varying degrees of expansion following whole-genome duplication (WGD) events. Notably, the number of 14-3-3 gene family members between A. lyrata and A. thaliana remained similar despite the former having approximately 1.66-fold larger genome size. In contrast, the number of 14-3-3 gene family members in A. pumila and C. sativa increased in proportionately to their genome size, while gene members in the more distantly related species to A. thaliana, B. oleracea, showed irregular expansion patterns. Selection pressure analysis revealed that 14-3-3 homologs in all the five species underwent purifying selection, with the group ε members experiencing relatively weaker purifying selection. Cloning of ApGRF6-2 gene from A. pumila indicated that the ApGRF6-2 protein was localized in the cell membrane and cytoplasm, while ectopic overexpression of ApGRF6-2 in A. thaliana could promote early flowering by upregulating the expression of floral meristem identity genes.
conclusionThis study provides a comprehensive and systematic identification of the 14-3-3 gene family members in five Brassicaceae species using updated genome sequences, and the results could form a basis for further validation of functional and molecular mechanisms of 14-3-3 genes in plant growth, development, abiotic stress responses, as well as flowering regulation.
