Figure 8

Drought stress analysis of GhMPK16 -overexpressing Arabidopsis. (A) Phenotypes of wild-type (WT) and transgenic plants (#2 and #5) plants withheld from water for 15 d at the vegetative stage. (B) Seed germination of wild-type (WT) and transgenic plants (#2 and #5) after 4 days on 1/2 MS agar medium containing 50 mM mannitol. (C) Germination percentage of seeds on 1/2 MS agar medium containing 50 mM mannitol. Germination was defined as the emergence of the root radical and was scored daily. Data are the mean ± SE (n = 4) from three independent experiments. (D) Growth of wild-type (WT) and transgenic plant (#2 and #5) seedlings after 100 mM mannitol treatment. Photos were taken 10 d after mannitol treatment. (E) Root length of wild-type (WT) and transgenic plant (#2 and #5) seedlings after 100 mM mannitol treatment for 12 d. Data are the mean ± SE (n = 6) from three independent experiments. Different letters indicate significantly different at P < 0.05 according to Duncan's multiple range test.
