The markedly different bacteria in the endophytic bacterial communities between healthy roots and clubroots. a LefSe analysis. The cladogram shows the taxa with marked differences in the two endophytic bacterial communities. Red and blue indicate different groups, with the classification of taxa at the level of class, order, family, and genus shown from inside to the outside. The red and blue nodes in the phylogenetic tree represent taxa that play an important role in the two endophyte communities. Yellow nodes represent taxa with no significant difference. b Student’s t-test bar plot of the endophytic bacterial communities at the genus level in healthy roots and clubroots. p < 0.05*, p < 0.01**, p < 0.001***. R, healthy roots. C, clubroots
