Figure 3. Histochemical detection of gusA gene expression in ‘Pinova’ transgenic apple lines. Ten individual leaves of each transgenic line were randomly selected and used for a GUS staining procedure. Five general classes of expression patterns were observed (class 1: tissue completely dark blue or blue coloured; class 2: the major part (70-80%) of the tissue is blue, partially small white spots; class 3: tissue completely light blue colored; class 4: the major part (70-80%) is white, partially small blue spots; class 5: tissue completely white).
