Encoded by a cryptic gene, a new viral protein out of the shadows

Due to the small size of their genome, plant viruses multiply expression strategies to produce the proteins required for their proliferation. The team of Veronique Ziegler-Graff, in collaboration with the University of Cambridge bioinformatics team (Great Britain) and a researcher from Iowa State University, Ames (USA) discovered in a family of viruses Luteoviridae, a new small gene encoding a protein essential to viral transport in the plant and remained unnoticed until now because of his unconventional translation fashion. This work is published in the journal PLoS Pathogens.
