在丛枝菌根共生过程中，根的定殖响应于植物的生理状态而被调节，调节发生在局部和系统。在这里，我们确定了差异表达的基因编码CLAVATA 3/ESR相关（CLE）肽，负调控定植水平，通过调节根独脚金内酯含量。CLE功能需要受体样激酶SUNN;因此，CLE-SUNN-独脚金内酯反馈环是植物调节定殖水平的一种途径。
During arbuscular mycorrhizal symbiosis, colonization of the root is modulated in response to the physiological status of the plant, with regulation occurring locally and systemically. Here, we identify differentially expressed genes encoding CLAVATA3/ESR-related (CLE) peptides that negatively regulate colonization levels by modulating root strigolactone content. CLE function requires a receptor-like kinase, SUNN; thus, a CLE-SUNN-strigolactone feedback loop is one avenue through which the plant modulates colonization levels.
