, also known as laurel dodder or love vine, is a stem hemiparasite of the Lauraceae family. It has long been used for medicinal purposes in many countries and has increasingly influenced agricultural and natural ecosystems by its effects on a wide range of host species. Previous studies have focused on the taxonomy and evolutionary position of different , with the pan-tropical species being the most widely studied. However, -host interactions have never been reviewed, which is an essential issue related to the understanding of mechanisms underlying plant hemiparasitic and the assessment of benefits and damage caused by aerial parasitic plants. This review explores the parasitic habits, worldwide distribution, and host range of , and examines its impacts on the biology of host plants and the overall influence of environmental changes on -host associations. We also comment on areas of future research directions that require to better understanding -host interactions. It appeared that some traits, such as flowering phenology, facilitated 's widespread distribution and successful parasitism and that preferred woody species rather than herbaceous species as a host, and preferred species from certain families as hosts, such as Fabaceae and Myrtaceae. Cassytha often decreased biomass and impacted the physiology of host species and global environmental changes seemed to intensify the negative impacts of on their hosts. was not only a noxious weed, but can also function as a biocontrol agent to mitigate alien plant invasion.
无根藤，又称月桂菟丝子或爱之藤，是樟科的一种茎寄生半寄生植物。在许多国家，它长期以来一直被用于药用，并且通过对多种寄主物种的影响，对农业和自然生态系统的影响日益增大。以往的研究主要集中在不同无根藤的分类学和进化位置上，泛热带物种无根藤是研究最为广泛的。然而，无根藤与寄主的相互作用从未被综述过，这是一个与理解植物半寄生机制以及评估气生寄生植物所造成的利弊相关的重要问题。本综述探讨了无根藤的寄生习性、全球分布和寄主范围，并研究了其对寄主植物生物学的影响以及环境变化对无根藤与寄主关系的总体影响。我们还对未来研究方向的领域进行了评论，这些领域需要更好地理解无根藤与寄主的相互作用。似乎某些特征，如开花物候，促进了无根藤的广泛分布和成功寄生，并且无根藤更喜欢木本物种而非草本物种作为寄主，并且更喜欢某些科的物种作为寄主，如豆科和桃金娘科。无根藤通常会降低生物量并影响寄主物种的生理，全球环境变化似乎会加剧无根藤对其寄主的负面影响。无根藤不仅是一种有害杂草，还可以作为一种生物防治剂来减轻外来植物入侵。
