Figure 7
Southern blot analysis of genomic DNA from hairy roots. Images of root tips on top of lanes correspond to independent root events used for DNA extraction. DNA was digested with BsrGI and hybridized with a 32P-labeled gfp probe. "Williams82" is DNA from roots induced with A. rhizogenes harboring no promoter construct, "Williams82 +" is Williams82 DNA plus 10 pg of respective plasmid, representing a single transgene copy in the soybean genome.
