a, Random forest modelling was used to determine environmental variables associated with microbiome type. The abbreviations are explained in Methods. b, PDSI of the location was the best predictor of microbiome type, explaining more than 50% of the variance. The upper and lower hinges of the boxes represent the first and third quartiles and the central line the median, with n = 269 plants in cluster 1 and n = 192 plants in cluster 2. c, The mean PDSI throughout Europe for January to April 2018.
