1 · What the graph read from it

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.

2 · The registry

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 B3 gene family plays a vital role in plant development and stress response. Despite the significance of these genes, an extensive genome-wide analysis of the B3 family in apple (Malus domestica Borkh.) has not yet been conducted.

resultsA total of 100 MdB3 genes were identified in apple, and their homologous relationships, chromosome positions, gene structures, and promoter cis-acting elements were analyzed. These MdB3 genes were divided into five subfamilies: ARF, HIS, REM, RAV and ABI3. Analysis of the promoter indicated that the apple MdB3 genes may be closely associated with hormone signaling and stress response mechanisms. qRT-PCR analysis was performed on 30 MdB3 genes. Under salt stress, MdB3 genes expression was diversified, up-regulated, or down-regulated. Salt stress treatment induced the expression of several MdB3 genes, among which MdREM19 was significantly expressed and found to be positively correlated with the salt tolerance of different apple rootstocks. Further analysis showed that overexpression of MdREM19 improves the salt tolerance in Arabidopsis.

conclusionThe above results provide a general understanding of the characteristics, evolution, and function of the apple B3 family, laying the foundation for further improving apple’s salt tolerance.
