| 摘 要： | The specific ACC oxidase 1 gene fragment of tomato was cloned and prepared for a probe which was used to hybridize with total RNAs that were extracted from the materials treated with ethylene and different environmental stresses, such as drought, water recovery, flood, wound and temperature, respectively. Northern blot analysis indicated that the expression of LeACO1 was restrained by drought, while strongly induced by water recovery and exogenous ethylene. After treated by flood stress, the expression level of I_eACO1 in leaves had no distinctively changes, while its expression level in stems was rapidly increased. Moreover, the expression of LeACO1 in tomato stems could be induced at the temperature of 37 degree. In addition, wounding had no influence on the expression of LeACO1.
