Abstract:
Gastrodia elata Blume, a fully mycoheterotrophic perennial plant of the family Orchidaceae, is a traditional Chinese herb with medicinal and edible value. Interestingly, G. elata requires symbiotic relationships with Mycena and Armillaria strains for seed germination and plant growth, respectively. However, there is no comprehensive summary of the symbiotic mechanism between fungi and G. elata. Here, the colonization and digestion of hyphae, the bidirectional exchange of nutrients, the adaptation of fungi and G. elata to symbiosis, and the role of microorganisms and secondary metabolites in the symbiotic relationship between fungi and G. elata are summarized. We comprehensively and deeply analyzed the mechanism of symbiosis between G. elata and fungi from three perspectives: morphology, nutrition, and molecules. The aim of this review was to enrich the understanding of the mutualistic symbiosis mechanisms between plants and fungi and lay a theoretical foundation for the ecological cultivation of G. elata.
摘要:
天麻,兰科的一种完全杂种的多年生植物,是一种具有药用和食用价值的传统中草药。有趣的是,G.elata需要与Mycena和Armillaria菌株的共生关系,以实现种子萌发和植物生长,分别。然而,真菌与elata之间的共生机制没有全面的总结。这里,菌丝的定殖和消化,营养的双向交换,真菌和G.elata对共生的适应,并综述了微生物和次生代谢产物在真菌与elata共生关系中的作用。从形态学、形态学、营养,和分子。本文旨在丰富对植物与真菌共生机制的理解,为白花菜的生态栽培奠定理论基础。
