Dodders ( spp.) are holoparasitic plants that enwind stems of host plants and penetrate those by haustoria to connect to the vascular bundles. Having a broad host plant spectrum, spp infect nearly all dicot plants - only cultivated tomato as one exception is mounting an active defense specifically against . In a recent work we identified a pattern recognition receptor of tomato, "Cuscuta Receptor 1" (CuRe1), which is critical to detect a "Cuscuta factor" (CuF) and initiate defense responses such as the production of ethylene or the generation of reactive oxygen species. CuRe1 also contributes to the tomato resistance against . Here we point to the fact that CuRe1 is not the only relevant component for full tomato resistance but it requires additional defense mechanisms, or receptors, respectively, to totally fend off the parasite.
菟丝子（菟丝子属）是全寄生植物，它们缠绕宿主植物的茎，并通过吸器穿透宿主植物以连接到维管束。菟丝子属植物具有广泛的宿主植物谱，几乎能感染所有双子叶植物——只有栽培番茄是个例外，它能对菟丝子属植物发起特异性的主动防御。在最近的一项研究中，我们鉴定出了番茄的一种模式识别受体，即“菟丝子受体1”（CuRe1），它对于检测“菟丝子因子”（CuF）以及启动防御反应（如乙烯的产生或活性氧的生成）至关重要。CuRe1也有助于番茄对菟丝子属植物产生抗性。在此我们指出，CuRe1并非番茄完全抵抗菟丝子属植物的唯一相关成分，而是分别需要其他防御机制或受体才能完全抵御这种寄生植物。
