Southern-blot analysis of the
AtGSK1 gene. Genomic DNA was digested with restriction
enzymes and size separated onto a 0.8% agarose gel. The DNA was then
transferred onto a nylon membrane and UV cross-linked. Hybridization
was carried out with the AtGSK1 cDNA at 65°C
overnight. E, H, and S indicate EcoRI,
HindIII, and SacI, respectively.
