Exchanges of mRNA were shown between host and stem parasites but not root parasites. (Orobanchaceae) is a holoparasitic herb which parasitizes on the roots of woody plant (Chenopodiaceae). We used transcriptome sequencing and bioinformatic analyses to identify nearly ten thousand mobile mRNAs. Transcript abundance appears to be a driving force for transfer event and mRNA exchanges occur through haustorial junction. Mobility of selected mRNAs was confirmed and in sunflower- heterologous parasitic system. Four . →. mobile mRNAs appear to facilitate haustorium development. Of interest, two mobile mRNAs of putative resistance genes and cause root-specific hypersensitive response and retard parasite development, which might contribute to parasitic equilibrium. The present study provides evidence for the large-scale mRNA transfer event between a woody host and a root parasite, and demonstrates the functional relevance of six . genes in host-parasite interactions.

梭梭（藜科）和草本根全寄生虫肉苁蓉（列当科）之间的大规模 mRNA 转移

宿主和茎寄生虫之间存在 mRNA 交换，但根寄生虫之间没有。 （列当科）是一种全寄生草本植物，寄生在木本植物（藜科）的根部。我们使用转录组测序和生物信息学分析来识别近万个移动 mRNA。转录本丰度似乎是转移事件的驱动力，并且 mRNA 交换通过吸器连接发生。选定的 mRNA 的流动性在向日葵异源寄生系统中得到了证实。四. →。移动 mRNA 似乎有利于吸器的发育。有趣的是，推定抗性基因的两个可移动 mRNA 会引起根部特异性过敏反应并阻碍寄生虫发育，这可能有助于寄生虫平衡。本研究为木本宿主和根部寄生虫之间的大规模 mRNA 转移事件提供了证据，并证明了 6 个基因的功能相关性。宿主-寄生虫相互作用中的基因。
