FIGURE 2 AR156-triggered ISR induced the accumulation of
phytoalexin synthesis and secretion-related genes.
(A) Hierarchical clustering analyses of DEGs related to phytoalexin
synthesis and secretion-related genes. Color scale denotes FPKM values.
(B-H) Validation of RNA-seq data for seven selected genes by RT-qPCR.AtActin1 was used as an internal control. The expression level of
these genes in Col-0 was set to 1. (I) Measurement of camalexin
accumulation in Arabidopsis ecotype Col-0 wild type treated with
5 × 107 CFU/mL of AR156 and 0.85% NaCl. Data
represent mean ± SD (n = 3). Statistical analyses were performed between
Mock and AR156 (**, P < 0.01; **, P < 0.01;
Student’s t -test).
