中文摘要:
【目的】 小分子热休克蛋白(sHSPs)能够被环境胁迫所诱导,不同温度可诱导中华稻蝗体内sHSPs基因表达。【方法】 本文采用实时荧光定量PCR(RT-qPCR)技术,分析不同温度处理后中华稻蝗Oxya chinensis体内6个OcsHSPs基因的表达。【结果】 结果表明,OcHSP19.1、OcHSP19.8、OcHSP20.4和OcHSP20.7基因的表达水平在27、32和37℃相同处理时间没有显著变化,但其表达量均在42℃显著升高,尤其是在42℃处理后2 h表达量升高明显。OcHSP21.1和OcHSP23.8基因的表达水平在不同温度处理后无显著变化。多因素方差分析结果表明,基因与处理温度间具有显著的交互作用。【结论】 由此可见,温度能够对中华稻蝗sHSPs基因的表达产生影响,但是,不同温度处理下各基因的表达模式存在差异。
英文摘要:
[Objectives] Small heat shock proteins (sHSPs) can be induced by environmental stress. Different temperatures can induce the expression of sHSPs genes in Oxya chinensis. [Methods] The effect of temperature on the mRNA expression patterns of six OcsHSP genes in fifth-instar nymphs of O. chinensis was analyzed using Real-time quantitative PCR. [Results] There was no significant difference in the expression levels of OcHSP19.1, OcHSP19.8, OcHSP20.4 and OcHSP20.7 at 27, 32 and 37℃, but expression levels significantly increased at 42℃, especially after 2 h at 42℃. There was no significant difference in the expression levels of OcHSP21.1 and OcHSP23.8 at different temperatures. Multiple factor analysis of variance indicated that there was a significant interaction between temperature and gene. [Conclusion] Temperature can affect the expression of sHSPs genes in O. chinensis but different genes respond differently to temperature.
