Microbe-induced plant resistance against insect pests depends on timing of inoculation, but is consistent across climatic conditions

To cope with abiotic and biotic stressors, plants have developed mutualistic associations with beneficial soil microbes, but little is known about how extreme abiotic conditions impact microbe-induce resistance to insect herbivores.
Extreme temperatures are often accompanied by extremes in plant water availability, which together reduce plant growth and change plant physiology. There are potential consequences for increasing plant susceptibility to biotic stresses, and this poses a real challenge for plant productivity.
We evaluated how the effects of beneficial soil bacteria (Acidovorax radicis N35e) on barley plant growth and resultant resistance against aphid infestation (Sitobion avenae) were impacted by a single heatwave event across a plant water availability gradient. We also tested if timing of bacterial inoculation (before or after the temperature treatment) affected bacteria-plant interactions on aphids.
We found that heatwaves affected plant biomass allocation from abovegrou..., This study describes a pot experiment performed in climate chambers, using barley plants. Presented data represent values measured from individual plants (in rows). For detailed descriptions, we refer to the materials and methods of the paper., , # Microbe-induced plant resistance against insect pests depends on timing of inoculation, but is consistent across climatic conditions

## Description of the data and file structure

The data is presented in an Excel table. The first tab 'Metadata description' describes the metadata in the required detail. The second tab 'Raw data' provides all raw data measurements, with a series of explanatory variables (columns A-J), followed by a series of response variables (columns K-V).
