Abstract: The ethylene mutants of Arabidopsis thaliana, including ein2-5, ein3-1, EIN3ox, EIL1ox and wild type Col-0 were conducted to investigate the morphological difference in control and drought stress. It is demonstrated that the rosette leaf diameter, leaf area, inflorescence, water potential of four ethylene mutants and A. thaliana wild type were significantly different under the conditions of drought stress, so were the morphology adaptation features of the mutants. These results indicate that ethylene is actively involved in shaping the plant morphology, and has a close correlation with plant drought-resistance.

Key words: Arabidopsis thaliana, ethylene, mutant, drought stress
