摘要:

以木本植物蒙古沙冬青的叶片和根为材料,采用改良Trizol 法提取总RNA 。结果表明,与传统Trizol 法相比,改良Trizol 法能有效去除提取过程中残留的异硫氰酸胍、β-巯基乙醇以及植物本身的糖、酚类物质,获得高质量总RNA 。改良Trizol 法提取总RNA 技术已被成功应用于蒙古沙冬青转录组数据库的建立。该方法可为木本植物提取高质量RNA 提供借鉴。

Abstract:

Total RNA was extracted using an improved Trizol method, with the leaves and roots of xylophyta, Ammopiptanthus mongolicus (Maxim)Cheng f. The result showed that compared to traditional Trizol method, the improved Trizol method can effectively remove residual guanidinium isothiocyanate, beta-mercaptoethanol in extraction process, as well as the sugar and polyphenols of the plant itself, and high-quality total RNA was obtained. The improved Trizol method has been successfully applied to transcriptome database constrction of A. mongolicus. It also provided a reference for xylophyta to extract high-quality RNA.
