Histochemical localization of GUS activity in 13-HPL promoter lines. Tomato fruits at three developmental stages (mature green, orange, and ripe red) were cut transversely and stained for GUS activity as described in “Materials and Methods.” WT, Fruits from nontransformed MicroTom plants; Pro35S, fruits from the constitutive promoter; ProHPL:GUS-high, fruits from a 2-kb promoter transgenic line with high expression level; ProHPL:GUS-low, fruits from a 2-kb promoter transgenic line with low expression level.
