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

key messageIn tomato, the 25 AHL family members were classifi ed into three subfamilies. SlAHL5 and SlAHL25 belonged to CladeB, interacted and enhanced salt and osmotic stress tolerence of transgenic Arabidopsis. AT-hook motif nuclear-localized (AHL) proteins participate in plant growth, development, and response to abiotic stress. Their functions in the resistance to salt and osmotic stresses are largely unknown in tomato. Here, a total of 25 AHL genes in the tomato (Solanum lycopersicum) genome were identified. Phylogenetic and gene structure analyses indicated that they were classified into two clades and three subfamilies. Synteny relationship analysis demonstrated that all paralogous SlAHL pairs evolved under purifying selection. Promoter structure analysis revealed that many stress-related and phytohormone-related cis-acting elements existed. Gene expression pattern assays indicated that they had significantly different expressions in various organs, and most of them were up-regulated by high salinity and/or osmotic stress. Yeast two-hybrid (Y2H) assays demonstrated that SlAHL5 and SlAHL25, two nucleus-localized members in Clade B, interacted with each other to form a heterodimer, with SlAHL5 having self-activation activity, which is absent in SlAHL25. Constitutive expression of either SlAHL5 or SlAHL25 increased the resistance of transgenic plants to both salt and osmotic stresses, as revealed by the promoted primary root growth and biomass production, the relatively higher chlorophyll and proline content, and the enhanced catalase (CAT) and peroxide dismutase (POD) activity under both stress conditions. Our study on SlAHL genes under different stress conditions reported here provides a basis for further functional analysis of SlAHL genes, as well as for the development of new breeding strategies to improve resistance to multiple abiotic stresses in tomato.
