Identification of ANS gene regulating fruit color in jujube (Ziziphus jujuba Mill. cv. Lingwuchangzao) and analysis of its expression under elevated temperature and drought stress.
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 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
backgroundThe anthocyanin synthase (ANS) gene is pivotal in plant anthocyanin biosynthesis, significantly influencing fruit coloration. Despite extensive on various studies, there remains a notable absence of research on the regulatory functions of the ANS gene in the 'Lingwuchangzao' variety under elevated temperature and drought stress.
resultsIn this study, 107 ZjANS genes were identified. Analyses of their physicochemical properties and gene structures revealed that most are localized in the cytosol and nucleus, with only seven ZjANS genes exhibiting basic characteristics. All genes contained the conserved domains 2OG-FeII_Oxy and DIOX-N. Chromosomal localization and Ka/Ks analysis indicated that these genes are distributed across 12 chromosomes, with 22 tandem gene pairs, suggesting purifying selection. Phylogenetic and synteny analysis demonstrated that ZjANS genes are evolutionarily conserved, forming collinear gene pairs with four species. Cis-acting element analysis identified elements related to anthocyanin synthesis and environmental stress, such as LTR and MBS. Predictions of protein interaction indicated that certain ZjANS proteins interact with MYB, CHI, and GA proteins, potentially involved in the anthocyanin synthesis pathway. Transcriptome and qRT-PCR analysis revealed that thirteen ZjANS genes positively respond to coloring in jujube under elevated temperature and drought stress, with ZjANS17 identified as particularly significant.
conclusionThis study identified 107 ZjANS genes and systematically analyzed their evolutionary conservation. Thirteen ZjANS genes were found to positively influence fruit coloring in 'Lingwuchangzao' under elevated temperature and drought stress. These findings provide a foundation for further investigations into ZjANS genes and the breeding new jujube varieties.
