Arabidopsis seedling growth was inhibited by elf18 and VirB2 peptide treatments. Plant widths of wild-type, RTNLB4 O/E transgenic (A), and rtnlb4 mutant plants (B) were determined after treatment with 20 μM elf18 peptide or the mock control (dH2O) for 2 weeks. Plant widths of wild-type and efr-1 and fls2 mutants (C) were also measured after treatment with 20 μM elf18, Agro-flg22 or the mock control (dH2O). Five VirB2 peptides and the mock control (DMSO) were used to treat wild-type and efr-1 and fls2 mutants (D). Seedlings of wild-type, RTNLB4 O/E transgenic (E) and rtnlb4 mutant plants (F) were treated with two VirB2 peptides, S111-T58, or I63-I80, and the mock control (DMSO). Plant widths of these plants were determined after 2-week treatments. Data are mean ± SE from three independent experiments. More than 15 seedlings of each type plant for each treatment were examined in each independent experiment. Data were analyzed by Duncan tests and means with different letters were significantly different (p < 0.05).
