摘要:
查尔酮合成酶(chalcone synthase,CHS)是植物类黄酮合成途径中的一个关键限速酶,参与植物中多个合成代谢途径,包括花青素合成。通过 PCR 反应成功克隆出藜麦CHS基因(CqCHS1)的 cDNA 全长序列,并进行预测分析,包括CqCHS1基因结构和编码的蛋白质保守结构域。同时,利用 qRT-PCR 技术检测了在不同胁迫处理下CqCHS1的表达情况。结果表明,CqCHS1基因包含2个外显子和1个内含子,其编码的蛋白质由392个氨基酸残基组成。CqCHS1蛋白是亲水性蛋白质,不存在信号肽,定位于细胞质。进化分析显示,CqCHS1与拟南芥AtCHS1的亲缘关系最近,其基因功能可能存在相似性。此外,还发现在CqCHS1基因启动子区域存在多个与胁迫和激素响应相关的顺式作用元件。表达分析结果表明,藜麦幼苗中CqCHS1的表达不会受到干旱胁迫的影响,而外源脱落酸(ABA)处理会抑制CqCHS1的表达,低温胁迫则会诱导CqCHS1的表达。本研究结果为进一步探究藜麦CqCHS1的基因功能提供了基础。
