bean plant pictureOriginal Cultivar and modification methods

The bean variety, named EMBRAPA 5.1, was produced by means of the biolistic technique and the pBGMVRNAiAHAS vector, transforming the cultivar Olathe Pinto.

Characteristics of the modification

Two partial sequences of the AC1 gene of the Bean Golden Mosaic Virus (BGMV), one with sense and the other with anti-sense orientation, were introduced into the genome of the EMBRAPA 5.1, allowing the GM plant to resist the virus by silencing the homonymous viral gene.
In the genome of the plant was also introduced a variant of the ahas gene (als) caming from A. thaliana, which normally provides tolerance to Imdazolinone herbicide. However, in the EMBRAPA 5.1 the protein AHAS was not detectable by ELISA analysis, so the plant is not tolerant to the herbicide Imidazolinone.

Purpose of the modification

To produce a bean variety resistant to BGMV virus.
