摘要: 利用ADP - 葡萄糖焦磷酸化酶的保守序列设计引物, 采用RT-PCR 方法, 从白魔芋球茎组织的总RNA 中扩增出目标cDNA 片段, 并克隆到pUC18 载体中。序列分析后确认该片段属于一新的ADP - 葡萄糖焦磷酸化酶大亚基基因。

关键词: 魔芋, RT2PCR, ADP - 葡萄糖焦磷酸化酶大亚基基因

Abstract: PCR primers were designed based on the consensus domain of ADP-glucose pyrophos-phorylase. A cDNA fragment was amplified from the total RNA isolated from the yang corm of Amorphophallus albus via RT-PCT and cloned into plasmid pUC18. The determined sequence showed this cDNA fragment was homologous to the large subunit gene of ADP-glucose yrophosphorylase.

Key words: Amorphophallus, RT2PCR, ADP2glucose pyrophosphorylase large subunit gene
