The promoter activity of GmExo70J genes in the floral organs.
(A) Histochemical analysis of the promoter activities of GmExo70J1 (J1), GmExo70J7 (J7) and GmExo70J8 (J8) in the floral organs of transgenic Arabidopsis flowers. (B) Histochemical analysis of the promoter activities of GmExo70J7 (J7) in the filaments of stamen of transgenic Arabidopsis flowers. (C) Histochemical analysis of the promoter activity of GmExo70J8 (J8) in the anthers and pollens of transgenic Arabidopsis flowers.
