| Abstract: | Viruses play an important role in driving the formation of high biodiversity of ecosystems and the cycling of nutrients and organic matter in ecosystems. As a hot spot of microbial activity in cryosphere， cryoconite holes provide a special habitat for viruses， which drives viruses to survive and adapt to extremely cold habitats. This review presents some of the findings and discussions of viruses in the cryoconite holes on the surface of glaciers in recent years， which relate to the importance of cryoconite holes in the glacial ecosystems， the abundance， productivity and genetic diversity of viruses in cryoconite holes， the interaction between viruses and hosts， and the importance of viruses for the carbon cycle and food web of cryoconite holes. Moreover， this review summarizes the gaps in the current research on viruses in cryoconite holes： viral morphological diversity， viral degradation rate， isolation and culture， and the viruses in cryoconite on glacier surface. This article points out several aspects which need to be focused on in future research， and offers a reference for the further study of the important effects of viruses in cryoconite holes. Based on the former studies， it is put forwards a future prospect of the research on the viruses in cryoconite holes of the Qinghai-Tibet Plateau. |
