Seed treatments with GmPeps induce the expression of defence‐associated genes in foliage. Transcript levels of NBS‐LRR (nucleotide‐binding site leucine‐rich repeat gene) and RBOHD (Respiratory Burst Oxidase Protein D) were analysed by reverse transcription‐quantitative polymerase chain reaction (RT‐qPCR) in leaf samples collected 3 weeks after treatment of soybean seeds with water (control) or 1 µm synthetic GmPep1 (A), GmPep2 (B) or GmPep3 (C). Relative expression values for each gene were analysed by one‐way analyses of variance (ANOVAs). Treatments labelled with an asterisk are significantly different at α = 0.05. For all other pairs, P > 0.1. Error bars indicate the standard errors of the mean (SEMs).
