Expression of TTG1 under the control of its native promoter restores root hair formation in the ttg1Δ15aa mutant. (a) Root hair formation in the Col wild type, the ttg1Δ15aa mutant and the TTG1/ttg1Δ15aa transgenic plants. Seeds of Col wild type, the ttg1Δ15aa mutant, and the TTG1/ttg1Δ15aa transgenic plants were germinated and grown on ½ MS plates vertically. Pictures were taken from 7-day-old seedlings under a Motic K microscope by using an EOS 1100D digital camera. (b) Root hair density in seedlings of the Col wild type, the ttg1Δ15aa mutant, the TTG1/ttg1Δ15aa, and the TTG1Δ3aa/ttg1Δ15aa transgenic plants. Root numbers were count under a Motic K microscope, and root hair density was calculated. Date represence mean ± SD of 17–18 seedlings. *, Significantly different from that in the Col wuld type (student’s t test, p < 0.0001).
