Genomic DNA gel-blot analyses of the GmEXP1 and GmEXP2 genes. Ten micrograms of soybean genomic DNA was digested with EcoRV (RV), HindIII (H), or NcoI (N) and hybridized with the coding and gene-specific probes of the GmEXP1 and GmEXP2 cDNAs after labeling. A, Filter hybridized with the GmEXP1 coding sequence as a probe. B, Filter hybridized with the GmEXP1 gene-specific probe. C, Filter hybridized with the GmEXP2 gene-specific probe. Numbers on the left side indicate size markers.
