摘要: 为了揭示乙烯在植物与环境相互作用过程中的生物学功能,以拟南芥(Arabidopsis thaliana)的ein2-5、ein3-1、EIN3ox、EIL1ox 4种乙烯突变体与Col-0野生型为材料,对比研究它们在干旱胁迫条件下的生长和形态学变化。研究发现,干旱胁迫导致莲座叶直径、叶片面积、花序、水势等指标发生显著变化,同时不同突变体的形态适应特点呈现显著差异。这些结果表明,乙烯积极参与了植物形态塑造过程,与植物的抗旱性具有紧密相关性。

关键词: 拟南芥, 乙烯, 突变体, 干旱胁迫

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
