The multiple independent origins of plant parasitism suggest that numerous ancestral plant lineages possessed the developmental flexibility to meet the requirements of a parasitic life style, including such adaptations as the ability to recognize host plants, form an invasive haustorium, and regulate the transfer of nutrients and other molecules between two different plants. In this review, we focus on the Orobanchaceae, which are unique among the parasitic plants in that extant member species include the full range of host dependence from facultative to obligate parasites. The recent emergence of genomic resources for these plants should provide new insights into parasitic plant evolution and enable the development of novel genetic strategies for controlling parasitic weeds.
植物寄生的多起源性表明，许多祖先植物类群具有满足寄生生活方式要求的发育灵活性，包括识别宿主植物、形成侵入性吸器以及调节两种不同植物之间养分和其他分子转移的能力等适应特性。在这篇综述中，我们重点介绍列当科，该科在寄生植物中是独一无二的，因为现存的成员物种包括从兼性寄生到专性寄生的整个宿主依赖范围。这些植物的基因组资源的最新出现应该为寄生植物的进化提供新的见解，并为控制寄生杂草的新型遗传策略的发展提供可能性。
