From: Transcriptome analysis reveals key roles of AtLBR-2 in LPS-induced defense responses in plants
pLPS-induced free SA and SAG accumulation and SA-induced gene expression. (a) Quantification of the total levels of free SA and SAG were measured by HPLC using samples extracted from Arabidopsis treated with pLPS for the indicated time. (b) Among the 65 pLPS-induced AtLBR-2-dependent up-regulated genes, the expression of the 3 SA-related genes (PR1, LURP1, and PDR12) were analyzed by qRT-PCR in WT and the atlbr-2-1 mutants plants treated with SA. The mean values were calculated from the results of three independent experiments. Means ± standard errors are presented. Significant differences among the means were determined by two-way ANOVA followed by post hoc Bonferroni test compared to WT plants; *P < 0.05, **P < 0.01. FW, fresh weight
