一项对全世界真菌的大规模的基因调查揭示了真菌分布和多样性的全球模式。然而,这项研究还显示了研究人员对这些微生物及人类活动如何对它们造成影响所知道的是如此之少。Leho Tedersoo及其同事从世界各地365处收集了近1.5万个土壤样品并用焦磷酸测序技术来研究其中所含的真菌基因。他们的结果提示,植物与真菌的演化并非如科学家们过去所认为的那样相互交织在一起,而导致如今真菌多样化的主要驱动因子与气 A large-scale genetic survey of the world’s fungi reveals a global pattern of fungal distribution and diversity. However, the study also shows that researchers know so little about how these microbes and human activities affect them. Leho Tedersoo and colleagues collected nearly 15,000 soil samples from 365 sites around the world and examined the fungal genes contained therein using pyrosequencing. Their results suggest that the evolution of plants and fungi is not intertwined with what scientists thought they had in the past, leading to the main drivers of fungal diversification today
