Parasitic plants in the family Orobanchaceae, such as Striga, Orobanche and Phelipanche, often cause significant damage to agricultural crops. The Orobanchaceae family comprises more than 2000 species in about 100 genera, providing an excellent system for studying the molecular basis of parasitism and its evolution. Notably, the establishment of model Orobanchaceae parasites, such as Triphysaria versicolor and Phtheirospermum japonicum, that can infect the model host Arabidopsis, has greatly facilitated transgenic analyses of genes important for parasitism. In addition, recent genomic and transcriptomic analyses of several Orobanchaceae parasites have revealed fascinating molecular insights into the evolution of parasitism and strategies for adaptation in this family. This review highlights recent progress in understanding how Orobanchaceae parasites attack their hosts and how the hosts mount a defense against the threats.
列当科的寄生植物，如独脚金、列当属和黄顶菊属植物，常常对农作物造成严重损害。列当科约有100个属，2000多种植物，为研究寄生现象的分子基础及其进化提供了一个绝佳的系统。值得注意的是，一些能够感染模式宿主拟南芥的列当科寄生植物，如多色三丝列当和日本松蒿，已被确立为模式植物，这极大地推动了对寄生相关重要基因的转基因分析。此外，最近对几种列当科寄生植物的基因组和转录组分析，揭示了有关该科寄生现象进化及适应策略的迷人分子见解。本综述重点介绍了在理解列当科寄生植物如何攻击宿主以及宿主如何抵御这些威胁方面的最新进展。
