A dominant nuclear streptomycin resistance marker for plant cell transformation

Plant cells in photoheterotrophic culture respond to streptomycin by bleaching and retarded growth but no cell death. A new genetic marker for plant cell transformation has been developed that is based on the expression of the enzyme streptomycin phosphotransferase (SPT), and confers the ability to form green colonies on a selective medium. Coding sequences… CONTINUE READING
