Co-infection of two reoviruses increases both viruses accumulation in rice by up-regulating of viroplasm components and movement proteins bilaterally and RNA silencing suppressor unilaterally

open access: yesVirology Journal, 2017
Background Synergism between southern rice black-streaked dwarf virus (SRBSDV) and rice ragged stunt virus (RRSV) not only aggravates disease symptoms but also enhances their vector acquisition efficiencies by increasing both viruses’ titers in co ...

A double-agent microRNA regulates viral cross-kingdom infection in animals and plants

open access: yesThe EMBO Journal
Plant arbovirus infection is regulated by a delicate interplay between virus, vector, and host. While microRNAs are known to be transmitted across species, their role as cross-kingdom effectors in influencing arbovirus infectious cycles remains poorly ...
