This dataset contains the findings from a meta-analysis of defence priming in Arabidopsis thaliana from 267 experiments across 77 papers. Data are provided as a semicolon delimited CSV file. Plant resistance to biotic stressors can be strengthened by priming the defence response with organismal and non-organismal agents. Stimulation with such agents triggers a minor part of the plant defence response that confers greater speed, strength and/or endurance against subsequent threats. This defence priming of plants could enhance the protection of crops against pests and diseases while reducing the use of agrochemicals. This dataset presents aggregated effect size values resulting from defence priming with numerous agents and subsequent biotic stressors. Responses quantified in the recorded experiments include lesion area, feeding damage, bacterial growth, infection, disease severity, spore production, feeding duration, population increase, herbivore weight, time to pupation and/or reproduction rate.
