For example potato virus A (PVA; genus Potyvirus) -induced RNA granules contain both OLIGOURIDYLATE BINDING-PROTEIN 1 (UBP1) of plant SGs and VCS and AGO1 of PBs (Hafrén et al., 2015) showing that these granules cannot be classed unambiguously into PBs or SGs but that they have a unique composition defined by PVA infection (Figure 2B). Here, UBP1 is linked to infection.
