Whether mobile virus-derived siRNAs can pre-immunize uninfected plant tissues has been a long-standing assumption in plant biology. In this issue, Albertini et al. demonstrate that they indeed establish an AGO1-dependent immune zone of adjacent uninfected short-range cells, and this mobile pre-immunization is impacted...
Positive-sense RNA viruses using subgenomic RNAs (sgRNAs) cause severe crop losses, yet this conserved feature has rarely been exploited for antiviral engineering. Here, we constructed a virus-activated synthetic immune circuit, wherein viral sgRNA production drives host defense responses via a translation inhibition–t...

It is demonstrated that targeting the OSB1-ALD1 defense module represents a widespread and conserved geminivirus mechanism to subvert chloroplast immunity.

This study demonstrates that expression of tomato leaf curl New Delhi virus CP confers effective resistance against tomato yellow leaf curl China virus (TYLCCNV), another prominent geminivirus, and uncovers a novel mechanism by which a viral effector antagonizes viral CP-mediated host resistance during mixed viral infe...
