烟粉虱对菜豆金黄花叶病毒属病毒的传播:我国学者的研究进展与未来展望OA

Begomoviruses are a group of major pathogens that extract a heavy toll on the production of many crops such as tomato and tobacco in China.Begomoviruses are exclusively transmitted by the insect vector Bemisia tabaci under natural conditions,and the transmission process mediated by B.tabaci thus becomes one of the major factors driving the widespread of begomoviruses in the field.Here we reviewed the progresses made by Chinese scientists since 2000 in dissecting the factors impacting the transmission of begomoviruses by B.tabaci,begomovirus transport within B.tabaci,the induction and suppression on the immunity responses of B.tabaci by begomoviruses,and B.tabaci-begomovirus-plant tripartite interactions.Many factors including the cryptic species,gender and symbionts of B.tabaci may significantly impact the transmission efficiency of begomoviruses,and the transport of begomoviruses in B.tabaci relies on the factors of B.tabaci such as clathrin.Upon infection,begomoviruses induce or suppress the antiviral immunity responses of B.tabaci.Further,begomoviruses may affect the fitness and behavior of B.tabaci directly or in a plant-mediated manner,begomovirus infection may affect the modulation of plant physiology and biochemistry by B.tabaci,and B.tabaci infestation may modulate virus infection in host plants.Finally,we identified the key areas for future research to further dissect the molecular mechanisms underlying the differential virus transmission efficiency among cryptic species,the identification of viral receptors in B.tabaci,and the viral factors and mechanisms inducing antiviral defenses in B.tabaci,the processes and molecular mechanisms underlying B.tabaci-virus-plant tripartite interactions.
