Arabidopsis latent virus 1, a comovirus widely spread in Arabidopsis thaliana collections

What is it about?

We identified Arabidopsis latent virus 1 (ArLV1), a comovirus that infects the model plant Arabidopsis thaliana without causing any visible symptoms. It is efficiently spread by transmission via seeds to the plant progeny. ArLV1 is infectious to A. thaliana plants and another model plant, Nicotiana benthamiana. By analyzing public sequencing data, we found that ArLV1 is widely spread in A. thaliana laboratory collections worldwide. Moreover, it was also detected in wild A. thaliana plants collected from different locations in the Netherlands and Spain, suggesting that it is a virus that naturally occurs in A. thaliana.
