Tomato Yellow Leaf Curl Virus: Impact, Challenges, and Management

Abstract

Tomato yellow leaf curl virus (TYLCV) is one of the most studied plant viral pathogens because it is the most damaging virus for global tomato production. In order to combat this global threat, it is important that we understand the biology of TYLCV and devise management approaches. The prime objective of this review is to highlight management strategies for efficiently tackling TYLCV epidemics and global spread. For that purpose, we focus on the impact TYLCV has on worldwide agriculture and the role of recent advances for our understanding of TYLCV interaction with its host and vector. Another important focus is the role of recombination and mutations in shaping the evolution of TYLCV genome and geographical distribution.

Keywords: Geminiviridae; Tomato yellow leaf curl virus; disease management; plant–virus interaction; virus–vector interaction.
