Coinfection of Nicotiana benthamiana with Potato virus A (PVA, a potyvirus) and Potato leaf-roll virus (PLRV, a luteovirus) induces a synergistic interaction manifested by enhanced titers of PLRV. The helper component proteinase (HC-Pro) of potyviruses is involved in viral vascular movement and suppression of an antiviral defense mechanism in plants. Data… CONTINUE READING
