Recently, significant progress has been made in recognizing virus-aphid specificities and identifying the proteins involved in virus transmission by aphids. An essential role of the viral capsid protein in this process has been proved. Heterologous encapsidation between viruses in mixed infections may allow transmission by aphids of normally non-aphid-transmissible viruses or change virus-vector interactions. This review describes the most characteristic examples of the phenomenon. Recent findings regarding transmission by aphids of viroid encapsidated in the viral capsid protein, and of virus encapsidated in transgenic coat protein, are presented.
