These consensus documents were to contain information for use during the regulatory assessment of the particular product. In the area of plant biosafety, consensus documents would be initiated on the biology of certain crop plants and on selected traits. The first trait chosen to be reviewed was virus resistance. The Expert Group charged a task group to develop a document, and possible a workshop, that would identify information relevant to consideration of virus resistant crop plants developed through the use of viral coat protein genes. The Expert Group, through recommendations from the task group, also identified at least two "core" issues that should be addressed: (1) creation of new viruses through mechanisms such as recombination and transencapsidation (also referred to as "transcapsidation"); and (2) the potential for synergistic effects when a transgenic plant is infected by other indigenous viruses
