Genome-wide identification of the cotton ANK gene family and functional study of GhANK169 in response to heat stress.
Article in BMC plant biology, 2025. 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
backgroundHigh temperatures significantly impair the yield and quality of cotton. Ankyrin-repeat proteins (ANKs) are among the largest superfamilies of proteins in plants and play vital roles in both biotic and abiotic stress responses.
resultsIn this study, we identified and characterized members of the cotton ankyrin repeat protein (ANK) gene family, focusing on the ANK-TM subfamily member GhANK169, which was highly upregulated in the RNA-seq data of cotton plants exposed to 42 °C. Overexpression of GhANK169 in tobacco at 42 °C resulted in improved phenotypic resilience, enhanced antioxidant enzyme activity, and reduced relative electrolyte leakage (REL) and malondialdehyde (MDA) content. Conversely, silencing GhANK169 in cotton via virus-induced gene silencing (VIGS) renders plants highly susceptible to heat stress, with symptoms including accelerated water loss, reduced relative water content (RWC), elevated superoxide anion (O
conclusionThis study enhances our understanding of the cotton ANK gene family and offers valuable genetic resources for improving cotton heat tolerance mechanisms and breeding strategies.
