Southern-blot hybridization of genomic DNA from
antisense ATHCK2A1 transformants. Genomic DNA was
digested with HindIII, separated by electrophoresis,
transferred to a nylon membrane, and hybridized with a
32P-labeled cauliflower mosaic virus 35S promoter region
cut from pBI121 (Clontech). D, F, G, H, and M, Five different antisense
transformants.
