利用拟南芥Col-0合成了CEP肽，并对其进行了诱导病感性试验。当将热带炭疽菌作为非适应性真菌病原体使用时，分生孢子萌发形成菌丝样结构，并成功穿透表皮，最终引起疾病症状。在这种情况下，CEP肽可能抑制PEN2-而非pen3依赖性耐药。同样，CEP肽介导的疾病易感性对非适应性细菌病原体也有效。值得注意的是，这种诱导敏感性在缺乏先前鉴定的受体的拟南芥突变体上也很明显，这表明CEP肽通过一种未知的受体调节拟南芥免疫。
CEP peptide was synthesized and tested for induction of disease susceptibility using Arabidopsis Col-0. When Colletotrichum tropicale was used as a non-adapted fungal pathogen, the conidia germinated to form hyphal-like structures, which successfully penetrated epidermis, eventually causing disease symptoms. In such case, PEN2-, but not PEN3-dependent resistance was likely suppressed by CEP peptide. Similarly, the CEP peptide-mediated disease susceptibility was also effective to a non-adapted bacterial pathogen. Notably, such induced susceptibility was also evident on Arabidopsis mutants lacking the previously identified receptors, suggesting that the CEP peptide modulates Arabidopsis immunity through an unidentified receptor(s).
