The Amino-Proximal Region of the Coat Protein of Cucumber Vein Yellowing Virus (Family ) Affects the Infection Process and Whitefly Transmission.

Most plant viruses rely on vector transmission for their spread and specific interactions between vector and virus have evolved to regulate this relationship. The whitefly - transmitted cucumber vein yellowing virus (CVYV; genus , family ) is endemic in the Mediterranean Basin, where it causes significant losses in cucurbit crops. In this study, the role of the coat protein (CP) of CVYV for transmission and plant infection was investigated using a cloned and infectious CVYV cDNA and a collection of point and deletion mutants derived from this clone.
