The rapid production of reactive oxygen species (ROS) upon pathogen attack is generally considered a defense mechanism for microbial killing and an initiation of host defense responses in plants and animals. In this issue, Siddique et al. show that nicotinamide adenine dinucleotide phosphate oxidase-derived ROS function as a pathogenicity factor to promote the roundworm nematode infection in Arabidopsis thaliana, revealing the complex action of ROS in host-pathogen interactions.
病原体攻击时活性氧(ROS)的快速产生通常被认为是一种用于杀灭微生物的防御机制,也是动植物宿主防御反应的起始。在本期中,西迪克等人表明,烟酰胺腺嘌呤二核苷酸磷酸氧化酶衍生的ROS作为一种致病因子,促进拟南芥中蛔虫线虫的感染,揭示了ROS在宿主-病原体相互作用中的复杂作用。
