Promoter activities of GmPINs in transgenic soybean hairy roots. At least 10 independent transgenic roots for each GmPIN::GUS construct were subjected to GUS staining. Images show representative results in root tips and lateral roots after four-hour staining for all roots except (S), which was stained overnight.
