Identification and expression analysis of the Xyloglucan Transglycosylase/Hydrolase (XTH) gene family under salt stress in cowpea (Vigna unguiculata L.).
Article in BMC genomics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCowpea (Vigna unguiculata L.), a crucial global legume crop for food security, faces significant challenges in yield and quality due to NaCl stress, which disrupts normal growth and development by impacting cell wall integrity. The XTH gene family, involved in cell wall remodeling, plays a key role in enhancing NaCl tolerance by maintaining structural stability under adverse conditions.
resultsA total of 31 VuXTH gene family members were identified in cowpea in this study. Further analyses examined their physicochemical properties, gene structures, phylogenetic relationships, and collinearity. qRT-PCR revealed that VuXTHE.1, VuXTHIIIA.1, and VuXTHIIIB.2 exhibited significant upregulation under NaCl-induced salt stress, whereas VuXTHI_II.3, VuXTHI_II.18, and VuXTHIIIB.4 displayed significant downregulation under the same stress conditions.
conclusionsThese findings highlight the roles of these genes in modulating cell wall dynamics in response to NaCl stress, offering insights into the VuXTH gene family’s adaptation mechanisms. This study provides valuable knowledge for future research aimed at enhancing NaCl tolerance in cowpea and other crops.
