摘要
为了研究黄瓜脂氢过氧化物裂解酶基因13-Cs HPL在不同生物胁迫和非生物胁迫条件下的表达模式,本研究以黄瓜种质26号为材料,通过同源克隆的方法克隆了黄瓜氢过氧化物裂解酶基因13-CsHPL的cDNA全长并分析其序列特征;通过Real-time PCR技术检测了13-CsHPL在华北型26号黄瓜幼苗受到不同逆境胁迫条件下的表达模式。结果表明:13-Cs HPL基因的cDNA序列全长为1 478 bp,编码481个氨基酸,分子量为54.34 kD。黄瓜种质26号幼苗的13-Cs HPL基因在受到非生物胁迫如干旱、NaCl、甲基紫精、H2O2、损伤与外源激素MeJA、SA和灰霉侵染处理后其表达水平均显著升高。干旱、Na Cl、H2O2胁迫处理12 h时13-CsHPL的表达水平升高,其中H2O2处理12 h时13-CsHPL的升高最为明显,比对照显著增加了216.79%;在各个处理中,13-CsHPL对甲基紫精及损伤胁迫处理的响应较早,与对照相比,分别在6 h和8 h后显著升高,分别比对照显著增加了52.96%和146.67%。本研究可为黄瓜13-CsHPL参与抗逆性调控的分子机理提供帮助。
In order to study the expression patterns of hydroperoxide lyase gene 13-CsHPL in cucumber under different biotic and abiotic stresses, the cDNA full length of cucumber hydroperoxide lyase gene 13-CsHPL was cloned by homologous cloning and its sequence characteristics were analyzed with cucumber germplasm No.26 as the material. The Real-time PCR was used to detect the expression pattern of 13-CsHPL in the seedling of cucumber germplasm Huabei No.26 under different stress conditions. The results showed that the cDNA full length of 13-CsHPL was 1 478 bp, encoding 481 amino acids, and the molecular weight was 54.34 kD. The expression of 13-CsHPL in seedlings of cucumber germplasm 26 was significantly increased under abiotic stresses such as drought, NaCl, methyl violet, H_2O_2, wounding and exogenous hormones Me JA, SA and Botrytis cinerea infection. The expression of 13-CsHPL increased in 12 hours with drought, NaCl and H2 O2 treatment, and the increase of 13-Cs HPL was the most significant in H2 O2 treatment for 12 h, which was significantly increased by216.79% compared with the control. In each treatment, the response of 13-CsHPL to methyl viologenine and injury stress was earlier than that of the control, which increased significantly after 6 h and 8 h, and increased by 52.96% and 146.67%, respectively. These results might be helpful for the molecular mechanism of 13-CsHPL involved in the regulation of stress resistance of cucumber.
