Genome wide identification of BjSWEET gene family and drought response analysis of BjSWEET12 and BjSWEET17 genes in Brassica juncea.
Article in BMC plant biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundSugars Will Eventually be Exported Transporter (SWEET) gene family is a unique type of sugar transporter that plays a vital role in metabolic regulation, growth, development, and stress response in multiple species. This study aimed to systematically identify the SWEET gene family members and detect the regulation of gene expression and their potential roles of the SWEET gene family in Brassica juncea.
resultsA total of 66 BjSWEET (Brassica juncea Sugar Will Eventually be Exported Transporter) genes distributed across 17 chromosomes were identified. The gene structure and motifs were relatively conserved, with all members containing the MtN3/saliva domain. Phylogenetic analysis revealed that the SWEET gene family can be classified into four subfamilies (Clades I, II, III, and IV). Collinearity analysis revealed that there were 118 pairs of segment duplicates, indicating that some BjSWEET genes were obtained via segmental duplication. The promoter regions of the BjSWEET genes contained many plant hormone-related response elements, stress-related response elements, growth and development elements, and light-responsive regulatory elements. Furthermore, analysis of the expression profiles revealed that the expression levels of the BjSWEET genes differed among the eight different tissues. qRT‒PCR analysis of six selected BjSWEET genes revealed that the expression levels of BjSWEET17.2, BjSWEET17.4, BjSWEET12.2, and BjSWEET12.3 were significantly upregulated under drought treatment, suggesting that these genes may respond to drought stress in B. juncea.
conclusionThis study systematically identified and analyzed the SWEET gene family members in B. juncea for the first time, laying the foundation for further research on the molecular mechanisms of drought resistance in B. juncea and providing theoretical guidance for the application of these genes in other species.
