Special Issue Information

Dear Colleagues,

This Special Issue, "Interactions between Plant Pathogens and Insect Vectors: Implications for Virus Transmission and Control", delves into the intricate relationships between plant pathogens, insect vectors, and the resulting transmission of viruses. This collection of research articles sheds light on the multifaceted interactions that influence the spread of viral diseases in plants and explores potential strategies for effective control.

This Special Issue underscores the pivotal role of insect vectors, such as aphids, whiteflies, and leafhoppers, in transmitting viruses to plants. These vectors not only facilitate viral transmission but also impact the viral acquisition and inoculation processes. The complex interplay between vectors and viruses, as well as their interactions with the host plants, have far-reaching implications for disease development and progression.

Researchers within this Special Issue will investigate various aspects of these interactions, including the molecular mechanisms governing vector–virus–plant relationships, the influence of vector behavior on virus spread, and the ecological factors that shape these interactions in diverse environments. Additionally, this Special Issue will delve into cutting-edge techniques and technologies aimed at disrupting the transmission cycle, thus offering potential avenues for disease management and control.

By synthesizing current research findings, this Special Issue offers a comprehensive overview of the state of knowledge regarding the interactions between plant pathogens, insect vectors, and virus transmission. This knowledge not only advances our understanding of the fundamental processes driving disease dynamics, but also holds practical implications for devising novel strategies to mitigate viral infections in plants. Ultimately, the research presented in this Special Issue contributes to the broader goal of safeguarding agricultural productivity and food security in the face of emerging challenges posed by vector-borne plant diseases.

Best,

Dr. Mitsuru Okuda

The pandemic of Southern rice black-streaked dwarf virus (SRBSDV) in and after the late 2000s caused serious yield losses in rice in Southeast and East Asia. This virus was first recorded in China in 2001, but its exclusive vector insect, Sogatella furcifera, occurred there before then. To clarify the evolutionary origin of SRBSDV as the first plant virus transmitted by S. furcifera, we tested virus transmission using three chronological strains of S. furcifera, two of which were established before the first report of SRBSDV. When the strains fed on SRBSDV-infected rice plants were transferred to healthy rice plants, those established in 1989 and 1999 transmitted the virus to rice similarly to the strain established in 2010. SRBSDV quantification by RT-qPCR confirmed virus accumulation in the salivary glands of all three strains. Therefore, SRBSDV transmission by S. furcifera was not caused by biological changes in the vector, but probably by the genetic change of the virus from a closely related Fijivirus, Rice black-streaked dwarf virus, as suggested by ecological and molecular biological comparisons between the two viruses. This result will help us to better understand the evolutionary relationship between plant viruses and their vector insects and to better manage viral disease in rice cropping in Asia. Full article
