Abstract

Plant roots associate with diverse microbes (including bacteria, fungi, archaea, protists, and viruses) collectively called the root-associated microbiome. Among them, mycorrhizal fungi colonize host roots and improve their access to nutrients, usually phosphorus and nitrogen. In exchange, plants deliver photosynthetic carbon to the colonizing fungi. This nutrient exchange affects key soil processes, the carbon cycle, and plant health and therefore has a strong influence on the plant and microbe ecosystems. The framework of nutrient exchange and regulation between host plant and arbuscular mycorrhizal fungi has recently been established. The local and systemic regulation of mycorrhizal symbiosis by plant nutrient status and the autoregulation of mycorrhizae are strategies by which plants maintain a stabilizing free-market symbiosis. A better understanding of the synergistic effects between mycorrhizal fungi and mycorrhizosphere microorganisms is an essential precondition for their use as biofertilizers and bioprotectors for sustainable agriculture and forestry management.

植物生长中的菌根共生与逆境适应:从基因到生态系统。
植物根系与多种微生物(包括细菌、真菌、古生菌、原生生物和病毒)联系在一起,统称为根系相关微生物组。其中,菌根真菌定植在寄主的根上,改善寄主对营养物质的获取,通常是磷和氮。作为交换,植物将光合作用的碳传递给定居的真菌。这种养分交换影响关键的土壤过程、碳循环和植物健康,因此对植物和微生物生态系统有很强的影响。寄主植物与丛枝菌根真菌之间的营养交换和调控框架最近才建立起来。植物营养状况对菌根共生的局部和系统调节和菌根的自我调节是植物维持稳定的自由市场共生的策略。更好地了解菌根真菌和菌根圈微生物之间的协同作用是将它们用作可持续农业和林业管理的生物肥料和生物保护剂的必要前提。
