Bacterial community shifts upon chilling temperature treatment in experiments IV and V. a Four-week-old maize plants grown in field soil. Plants on the left and the right are grown under chilling (16 h/8 h light/dark regime and 17 °C/12 °C) and under normal (16 h/8 h light/dark regime and constant 21 °C) temperature conditions, respectively. b Principal coordinate analysis of the microbial communities in bulk soil and root endosphere. Effects of the variables temperature and compartment are given by differences in color and shape, respectively. PCoA plots are based on Bray-Curtis dissimilarity indices. c Overlap between the chilling-responsive families in experiments IV and V and the main microbiome. d Root endosphere bacterial families enriched (top) and depleted (bottom) in chilling experiments IV and V (relative abundance > 0.5%). The relative abundance of the families is presented; error bars represent the standard error
