The perspective for the use of genetically modified common beans in Brazil based on genetic diversity of Bean golden mosaic virus.

Bean golden mosaic is the most important viral disease affecting common beans (Phaseolus vulgaris) in Brazil. It is caused by Bean golden mosaic virus (BGMV) and is prevalent in all bean producing areas. Aiming to control the disease, a transgenic bean elite line was developed with an intron-hairpin construction to silence the AC1 viral gene. This line shows high resistance to BGMV with the capacity to contain the replication of the virus both in the greenhouse and in the field
