The Insight of Mycovirus from Trichoderma spp.

Abstract

Trichoderma spp. are used extensively in agriculture as a biological control agent to prevent soil-borne plant diseases. In recent years, mycoviruses from fungi have attracted increasing attention due to their effects on their hosts, but Trichoderma mycoviruses is in the beginning stage as the subject of extensive study. At present, eight researches were on the mycoviruses from Trichoderma spp. techniques of genome sequencing, elimination of dsRNA, detection of dsRNA, transmission of mycovirus were elaborated. With the deep research on the mycovirus, more and more effective methods for these basic researches should be applied. The topics about antagonism and biocontrol function of mycovirus will better push the deep exploration on the interaction among Trichoderma-mycovirus-plant (or pathogen), which also will have the driving role on seeking and screening more resources of Trichoderm spp. possessing biocontrol capabilities with mycoviruses.
