摘要:

共生菌和昆虫间存在广泛的营养共生关系。昆虫为共生菌提供营养物质和能量来源,共生菌向昆虫提供必需的营养素,帮助昆虫消化食物,参与氮素循环、维持正常的生理环境。共生菌和昆虫间还存在营养素代谢途径互补,这为两者的协同进化提供了动力。本文就共生菌对昆虫的营养功能、共生菌和昆虫间营养素的转运模式、昆虫对共生菌营养素生产和转运的调控等进行综述,以期为共生菌与宿主营养共生及其机制的深入研究提供参考。

Abstract:

There are a wide range of nutritional symbiosis between symbiotic bacteria and insect hosts. Insect hosts provide nutrition and energy sources to symbiotic bacteria,and symbiotic bacteria can provide essential nutrients to insects,help insects digest food,and participate in nitrogen cycle and maintain normal physiological environment of insect hosts. The shared metabolic pathways between certain symbiotic bacteria and insect hosts provide impetus for host-symbiont coevolution. To provide deep insight into the cross-feeding between symbiotic bacteria and hosts,this paper reviewed nutritional function of symbiotic bacteria on insect hosts,the transshipment mode of nutrients between symbiotic bacteria and insects,and the regulation of insects on the production and transshipment of nutrients from symbiotic bacteria.

Key words: insect, symbiotic microorganism, nutrition, co-metabolism, transshipment of nutrients, compensatory adaptation
