药用植物培养高产细胞系的选育

通过植物发酵培养获得有用的药用植物次生代谢物是解决药用植物资源问题的有效手段。然而，大多数有用的次生物质在植物细胞中含量极低。为此，在工业化生产中首先需要适时地对植物细胞进行选育和改良，以解决提高植物细胞中次生物质含量问题。本文对药用植物培养高产细胞系选育方法和研究作了概述，针对高产细胞系筛选、诱变育种和基因转移关键共性技术研究及对解决高产细胞系不稳定性问题进行了讨论。

Breeding of High-yield Clones in Cultivation of Medicinal Plants

It is an effective means to tap the resources of medicinal plants by the way of fermenting plants to obtain the secondary metabolites of useful medicinal plants. Nevertheless, most of useful secondary matters are extremely low in the cells of plants. For this reason, people have to first breed and improve the cells of plants in order to increase the content of secondary matters in industrialized production. This article summarizes the breeding methods and research of high -yield clones of medicinal plants and purposefully discusses the problems, such as the screening of high - yield clones, mutation breeding and gene transfer and the study of key techniques and its solution of the instability of high - yield clones.
