Welcome Pathogens: Transient Heat Dampens Immune Responses to Acibenzolar-S-Methyl in Apple Plants.

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
Climate change affects plant-pathogen interactions, with disease outcome varying depending on the pathosystem and environmental scenario. In Arabidopsis, a thermo-sensitive module of salicylic acid (SA) signalling makes immunity vulnerable to heat. The potent resistance inducer acibenzolar-S-methyl (ASM), an SA analogue that up-regulates transcription of defence genes, could restore plant protection under heat but not core SA signalling. Here, we investigated how high temperature rewires the ASM-induced responses of the apple immune system. We treated apple plants with ASM under contrasting heatwave scenarios and subsequently exposed them to Erwinia amylovora (the fire blight bacterium) or Venturia inaequalis (the apple scab fungus) while monitoring gene expression. While pre-exposing apple plants to high temperature did not change their susceptibility to pathogens, it drove a loss of ASM-induced protection. Transcriptomic analysis revealed broad dampening of ASM-regulation upon high temperature, for a wide range of biological processes beyond defence. We uncovered thermo-sensitive 'resistance' and 'susceptibility' marker genes with ASM-responsiveness being critically vulnerable to heat. We concluded that exposure to heatwaves prevents ASM from fully mounting its protective responses in apple, not only lowering defences but also offering more favourable hosting conditions. Our work highlights plant immunity as the joint outcome of resistant and susceptible responses.
