Citrus tristeza virus P33 Protein is Required for Efficient Transmission by the Aphid Aphis (Toxoptera) citricidus (Kirkaldy).

ABSTRACT: Plant viruses are threatening many valuable crops, and Citrus tristeza virus (CTV) is considered one of the most economically important plant viruses. CTV has destroyed millions of citrus trees in many regions of the world. Consequently, understanding of the transmission mechanism of CTV by its main vector, the brown citrus aphid, Aphis (Toxoptera) citricidus (Kirkaldy), may lead to better control strategies for CTV. The objective of this study was to understand the CTV-vector relationship by exploring the influence of viral genetic diversity on virus transmission. We built several infectious clones with different 5'-proximal ends from different CTV strains and assessed their transmission by the brown citrus aphid. Replacement of the 5'- end of the T36 isolate with that of the T30 strain (
