GhAOS integrates circadian rhythm and jasmonic acid signaling to regulate high temperature stress responses in cotton and Arabidopsis.

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
backgroundCotton (Gossypium spp.) cultivation is significantly challenged by high temperatures (HT), especially during reproductive stages, leading to male abortion and yield losses.
resultsThis study investigated the complex interplay between circadian rhythm (CR), HT, and jasmonic acid (JA) signaling in cotton and Arabidopsis. Disruption of CR led to reduced JA content, triggering bud yellowing and abscission at the tetrad stage (TS) in the HT-sensitive cotton line H05 and longer stigma in Arabidopsis. To elucidate the role of JA under continuous light (CL), targeting the JA biosynthesis gene GhAOS in cotton and using Arabidopsis mutants aos and aoc2 revealed accelerated drying, decreased JA content, and male sterility, alongside altered expression patterns of pivotal bioclock-associated genes (PRR1 and LHY). Additionally, mutant anthers manifested elevated ion leakage and H
conclusionsCurrent study investigated the complex interplay between CR, HT, and JA signaling pathways in cotton and Arabidopsis, focusing on their impact on male fertility under HT stress. These findings highlight the importance of JA and CR in plant fitness, crucial for future crop improvement and sustainable agriculture.
