摘要
克隆了葡萄查尔酮合成酶基因4(CHS4),并采用半定量RT-PCR技术,以actin为内参,分析了CHS4在巨峰葡萄果实发育阶段不同组织的表达。对CHS4的序列分析表明:CHS4含有1个内含子,2个外显子;与CHS1、CHS2、CHS3在核苷酸水平的同源性分别为99.3%、92.6%和76.0%。半定量RT-PCR分析结果表明:CHS4在果皮、果肉、种子、叶片和根系中均有表达,在花后30d的果皮中表达强烈,随后迅速降低,到花后70d表达又增强;CHS4在花后30~45d的果肉中表达强烈,随后迅速降低;在花后45d的种子中也表达强烈,随果实发育,其表达逐渐下降。高温处理抑制CHS4在巨峰葡萄幼叶中的表达,但诱导CHS4在幼根的表达。
