The promoter activity of GmExo70J genes in response to rhizobial infection.
(A) Histochemical analysis of the promoter activities of GmExo70J7 (GmExo70J7::GUS) and GmExo70J9 (GmExo70J9::GUS) in transgenic soybean hairy roots at 0 and 3 days post inoculation of rhizobia (dpi). (B) qRT-PCR analysis of GmExo70J7 and GmExo70J9 in soybean roots at 0, 3 and 6 dpi of rhizobia.
