疫霉属被称为“植物破坏者”，由大约120种致病物种组成。这些物种可能会对农业、环境和相关产业造成严重影响。马铃薯晚疫病菌(Phytophthora Infestans)引起的马铃薯晚疫病是世界上危害最大、危害最大的马铃薯和番茄病害。这种疾病每年造成数十亿美元的损失，并威胁着全球马铃薯市场。19世纪中叶，致病疫霉摧毁了美国和欧洲的很大一部分马铃薯种植园；这种病原体被广泛认为是1845年爱尔兰马铃薯饥荒的原因，导致100多万人死亡。采取了各种预防控制策略来预防疫霉感染。甲霜灵是防治疫霉最有效、最常用的杀菌剂。然而，这种杀菌剂的长期使用导致了严重的抗药性和环境问题。因此，开发防治疫霉的新方法是研究人员面临的一项十分紧迫的任务。疫霉的生活史可分为无性周期和有性周期。为了控制疫霉的有性繁殖，我们以前确定了两个信号分子的化学结构，即激素α1和α2，它们刺激异源物种的有性繁殖。无性循环是作物和林木中快速多周期流行病的驱动力
The genus Phytophthora, known as “plant destroyer,” consists of approximately 120 pathogenic species. These species could bring serious effects on agriculture, environment, and related industries. Potato late blight caused by Phytophthora infestans is economically the most important and most destructive potato and tomato disease worldwide. The disease causes annual losses of several billion dollars and globally threatens the potato market. In the middle of the 19th century, P. infestans destroyed a significant part of potato crop plantations in the USA and Europe; this pathogen is widely known as the cause of the Irish potato famine in 1845, resulting in the death of more than a million people. Various preventive control strategies are used to prevent Phytophthora infection. Metalaxyl, is the most effective and commonly used fungicide against Phytophthora. However, the long-term use of this fungicide led to serious resistance and environmental issues. Therefore, development of new methods to control Phytophthora is a very urgent task for researchers. The life cycle of Phytophthora can be separated into asexual and sexual cycles. To control the sexual reproduction of Phytophthora, we previously determined the chemical structures of two signaling molecules, namely, hormones α1 and α2, which stimulate sexual reproduction in heterothallic species. The asexual cycle is the driving force of rapid polycyclic epidemics in crops and forest trees during the
