  abstract = {{A}n appreciation of the risks caused by emergent plant viruses is critical in tropical areas that rely heavily on agriculture for subsistence and rural livelihood. {M}olecular ecology, within 10 years, has unraveled the factors responsible for the emergence of several of the economically most important tropical plant viruses: {R}ice yellow mottle virus ({RYMV}), {C}assava mosaic geminiviruses ({CMG}s), {M}aize streak virus ({MSV}), and {B}anana streak virus ({BSV}). {A} large range of mechanisms-most unsuspected until recently-were involved: recombination and synergism between virus species, new vector biotypes, genome integration of the virus, host adaptation, and long-distance dispersal. {A} complex chain of molecular and ecological events resulted in novel virus-vector-plant-environment interactions that led to virus emergence. {I}t invariably involved a major agricultural change: crop introduction, cultural intensification, germplasm movement, and new genotypes. {A} current challenge is now to complement the analysis of the causes by an assessment of the risks of emergence. {R}ecent attempts to assess the risks of emergence of virulent virus strains are described.},
