Interplay between symbiotic and defense transcriptional responses. (A) Log₂ fold changes of potential defense associated genes identified as induced in the early stages of symbiosis by Kouchi et al. (2004) were examined across our datasets. (B) Expression patterns of 71 commonly differentially expressed genes in early symbiotic samples compiled from Ml R7A inoculated roots and root hairs was analyzed in the spectrum of interacting bacteria. (C) Rs JS763 differentially regulated genes were examined for expression changes in early symbiotic and diverse strain datasets. (D) Venn diagrams showing the overlap in gene expression between early symbiosis, corresponding to a compiled list of genes that were responsive to either Ml R7A or NF in whole roots or root hairs, and response to pathogenic Rs JS763. Differentially expressed genes were filtered by a minimum fourfold change and a FDR p-value ≤ 0.05.
