Figure 3.

Trichome number on plants overexpressing GL1 and/or R in the ga1–3 background. The numbers represent average adaxial trichome numbers per leaf on the first three leaves of 10 rosettes from three independent experiments. Plants were grown in Petri dishes containing MSAR medium plus kanamycin. Compared with Figure 1, trichomes had fewer branches on average, presumably because the growth conditions in Petri dishes involved increased RH. Leaf 4 of these plants was not included, since ga1–3 35SGL1 35SR plants did not fully develop.
