Special Issue Information

Dear Colleagues,

Viral diseases are economically important in many agronomic systems, causing significant economic losses in many countries worldwide as global trade expands and climatic conditions shift. The interactions among viruses, insects, and plants are very important factors that are worthy of research and consideration because the knowledge of these specific interactions will contribute to the development of new and efficient management strategies for many important viral diseases.

The topic of virus–insect–plant interactions includes a wide range of perspectives, as demonstrated by the accumulation of a large amount of data from the omics fields. This growing field of study seeks scientific insights into the changes in host plants induced by plant viruses; the impacts on plant virus populations, evolution, and associated insect vectors resulting from specific virus–insect–plant interactions; the characterization of molecules known to be involved in interaction; the specific transmission of plant viruses through insect vectors; and the influences of environmental factors.

In this Special Issue, articles (original research papers, perspectives, hypotheses, opinions, reviews, and modeling approaches and methods) that focus on virus–insect–plant interactions at all levels are welcome.

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 Bemisia tabaci- transmitted cucumber vein yellowing virus (CVYV; genus Ipomovirus, family Potyviridae) 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 B. tabaci 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. Whitefly transmission of CVYV was abolished in a deletion mutant lacking amino acids in position 93–105 of the CP. This deletion mutant caused more severe disease symptoms compared to the cDNA clone representing the wild-type (wt) virus and movement efficiency was likewise affected. Two virus mutants carrying a partially restored CP were transmissible and showed symptoms comparable to the wt virus. Collectively, our data demonstrate that the N-terminus of the CVYV CP is a determinant for transmission by the whitefly vector and is involved in plant infection and symptom expression. Full article
