增温对外生菌根真菌的影响研究进展

全球变暖正深刻影响陆地生态系统.外生菌根(EM)真菌可与 2%的维管植物互惠共生,协助植物吸收养分,提高植物抗胁迫能力,影响土壤碳循环过程.目前大部分研究发现增温可以直接或间接影响EM真菌的分布、侵染率、探索类型及群落组成等,EM真菌的改变则可能对寄主植物及土壤碳库产生反馈.由于生态系统的复杂性,增温对EM真菌影响的研究因区域、树种、增温时长及方式等的不同而出现结论不一致的情况.因此,今后应加强增温与其他全球变化相关因子的交互实验,同时注重低纬度地区EM真菌以及EM真菌种内及种间关系的研究.
Progress in the Study of the Effect of Temperature Increase on Ectomycorrhizal Fungi
Global warming is profoundly affecting terrestrial ecosystems.Ectomycorrhizal(EM)fungi can be in reciprocal symbiosis with 2%of vascular plants,assisting them in nutrient uptake,improving plant stress resistance,and influencing soil carbon cycling processes.Most studies have found that war-ming can directly or indirectly affect the distribution,infestation rate,exploration type,and community composition of EM fungi,while changes in EM fungi may generate feedback to host plants and soil car-bon pools.Due to the complexity of ecosystems,studies on the effects of warming on EM fungi showed inconsistent conclusions depending on the region,tree species,duration,and mode of warming.There-fore,interaction experiments between warming and other global change-related factors should be strengthened in the future research,as well as EM fungi and intra-and inter-species relationships of EM fungi at low latitudes should be emphasized.
