Abstract

Parasitic plants use a special organ, the haustorium, to attach to and penetrate host tissues, forming phloem and/or xylem fusion with the host vascular systems. Across this haustorium-host interface, not only water and nutrients are extracted from the host by the parasitic plant, but also secondary metabolites, messenger RNAs, noncoding RNAs, proteins, and systemic signals are transported between the parasite and host and even among different hosts connected by a parasite. Furthermore, mycorrhizal fungi can form common mycelial networks (CMNs) that simultaneously interconnect multiple plants. Increasing lines of evidence suggest that CMNs can function as conduits, transferring stress-related systemic signals between plants. Between-plant signaling mediated by haustoria and CMNs likely has a profound impact on plant interactions with other organisms and adaptation to environmental factors. Here, we summarize the findings regarding between-plant transfer of biomolecules and systemic signals and the current understanding of the physiological and ecological implications of between-plant signaling.

进行植物信号。
寄生植物利用一种特殊的器官——吸器附着并穿透寄主组织,形成与寄主维管系统融合的韧皮部和/或木质部。通过这个吸器-寄主界面,寄生植物不仅从寄主中提取水分和营养物质,而且在寄主和寄主之间,甚至在寄主连接的不同寄主之间,还运输次生代谢物、信使rna、非编码rna、蛋白质和系统信号。此外,菌根真菌可以形成共同的菌丝网络(CMNs),同时连接多个植物。越来越多的证据表明,CMNs可以作为管道,在植物之间传递与压力相关的系统信号。由吸器和CMNs介导的植物间信号可能对植物与其他生物的相互作用和对环境因子的适应具有深远的影响。在此,我们总结了有关植物间生物分子和系统信号传递的研究结果,以及目前对植物间信号传递的生理和生态意义的理解。
