Bialaphos is a natural herbicide produced by the bacteria Streptomyces hygroscopicus[1] and Streptomyces viridochromeogenes.

Biapahos is made up of two alanine residues and the glutamic acid analog phosphinothricin and is commonly used as a gene sector in plants. Resistance plasmids include: pGreenII 0229 and pGreenII 0229 62-SK. pGreenII 0229 is derived from pGreenII 0000, a nos-bar cassette has been inserted into the HpaI site of the Left Border, providing resistance to bialaphos or phosphinothricin during plant transformation selection. pGreenII 0229 62-SK is derived from pGreenII 0229, the LacZ blue/white cloning selection has been replaced with a 35S-MCS-CaMV cassette that allows the insertion of a gene of interest into a 35S over-expression cassette.[2]
