Effect of temperature, vector life stage, and plant access period on transmission of banana bunchy top virus to banana.

abstract：:Resistance genes are a major tool for managing crop diseases. The networks of crop breeders who exchange resistance genes and deploy them in varieties help to determine the global landscape of resistance and epidemics, an important system for maintaining food security. These networks function as a complex adaptive sys...
