Promoter activity was analyzed in woodland strawberry hairy roots induced by A. rhizogenes. (A) Schematic representation of the T-DNA region DR5_ver2::eGFP. (B) Promoter activity is recapitulated in A. rhizogenes-transformed hairy roots. No eGFP fluorescence was detected in the transformed hairy root of WT; the 35S promoter drives eGFP constituent expression in all the tissue of transformed hairy roots; the DR5_ver2 promoter drives strong eGFP expression in the root meristem of transformed hairy root.
