Trichome formation on leaves of Col-0 wild type, the gis mutant and the 35S:TCL1 and 35S:TCL1/gis transgenic plants. (a) Trichomes on the first two rosette leaves of the Col-0 wild type, the gis mutant, and the 35S:TCL1 and 35S:TCL1/gis transgenic plants. Photographs were taken from the first two rosette leaves of 10-day-old soil-grown plants. Graph at the bottom showing the quantification of the trichomes on the first two rosette leaves. Data represent the mean ± SD of 10 plants. *significantly different form that in the 35S:TCL1 transgenic plants (P < 0.0001). (b) Trichomes on the first cauline leaves of the Col-0 wild type, the gis mutant and the 35S:TCL1 and 35S:TCL1/gis transgenic plants. Photographs were taken from the first cauline leaves of 5-week-old soil-grown plants. (c) Trichome numbers on the cauline leaves of the Col-0 wild type, the gis mutant and the 35S:TCL1 and 35S:TCL1/gis transgenic plants. Number of trichomes on the first three cauline leaves was count. Data represent the mean ± SD of 10 plants. Significantly different form that in the 35S:TCL1 transgenic plants (*P < 0.0001, #P < 0.0005)
