As a pararetrovirus and because of the non-canonical translation of its polycistronic pregenomic 35S RNA, Cauliflower mosaic virus (CaMV) is an original model system that has been extensively studied. Recent advances have improved our understanding of CaMV aphid transmission, cell-to-cell movement, protein expression and virus counter-defense strategy against host plant defense. Since P6/TAV is involved in many aspects of viral pathogenesis as well as in some replication steps, it is considered as the key player of CaMV infectious cycle. This paper reviews our current knowledge on CaMV multiplication and pathogenesis, with special emphasis on steps in which P6/TAV has a major role.
