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 Na⁺/H⁺ antiporter (NHX) family plays a crucial role in regulating intracellular Na and H homeostasis in plants. This study conducted a genome-wide analysis and expression assessment of peanut NHXs under different stress conditions.

resultsFourteen AhNHXs were identified based on the Na⁺/H⁺ exchange domain, and all contained the amiloride-binding site that inhibits Na+ transport in plants. Phylogenetic analysis grouped these genes into three subfamilies. Cis-regulatory element analysis identified elements associated with hormone signaling, stress responses, and tissue-specific expression. qRT-PCR results indicated their roles in salt stress, selenium stress, and tolerance to metal ion toxicity such as cadmium, manganese, and aluminum. For instance, AhNHX4, AhNHX5, and AhNHX7 were upregulated in roots under salt, cadmium, and aluminum treatments, whereas AhNHX7 was downregulated in roots under selenium and manganese stress and in leaves under all stress conditions.

conclusionsThis study examined the evolutionary, structural, and functional characteristics of the AhNHX family and highlighted their roles in multiple stress responses in peanut. These findings provide insight into potential applications for improving crop tolerance to abiotic stress.
