Recent advances on the plant manipulation by geminiviruses.

As intracellular parasites, viruses co-opt the molecular machinery of the cells they infect in order to multiply and spread, and the extensiveness and effectiveness of this manipulation ultimately determine the outcome of the interaction between virus and host. Members of the Geminiviridae family, causal agents of devastating diseases in crops, encode only a handful of multifunctional, fast-evolving proteins, which efficiently target host proteins to re-wire plant development and physiology and enable replication and spread of the viral genome. In this review, we offer an overview of the different steps in the geminiviral invasion of the host plant, and explore the knowns and unknowns in geminivirus biology.
