GmPR10 was homology with the PR10( pathogenesis-related proteins 10) gene in other plants. To investigate the expression and regulation of the GmPR10 gene in soybean,the 2 235 bp promoter region of 5'-flanking upstream of GmPR10 gene was isolated from the genomic DNA of soybean cultivars Suinong 10( with high resistance to Phytophthora sojae in Heilongjiang,China) by PCR,defined as p GmPR10. It was directionally replaced CaMV35S promoter of the expression vector pBI121. The plant expression vector of pBI121...
