Intact Genomics (ig®) K599 Chemically Competent Agrobacterium cells are made from a specific strain of  Agrobacterium rhizogenes, Agrobacterium rhizogenes (str R) pRi2659 (agropine type). K599 was originally isolated from cucumber exhibiting hairy root disease symptoms and has been widely used for hairy root transformation(1).

Agrobacterium rhizogenes is a soil-borne gram-negative bacterium that can infect most dicotyledons, a few monocotyledons and some gymnosperms.  K599 Chemically Competent Agrobacterium are optimized for the highest transformation efficiencies and are useful for transgenic operations of corn, soybean (wild soybean), cotton, peanut, dandelion, cowpea and other plants.  K599 Agrobacterium rhizogenes strain contains pRi2659 agrobacterium-type Ri plasmid and displays streptomycin resistance.
