Induced proliferation method for glehnia littoralis hairy roots

Abstract

The invention provides an induced proliferation method for glehnia littoralis hairy roots. The method comprises the following steps: obtaining glehnia littoralis aseptic seedlings; culturing agrobacterium rhizogenes for infection; performing co-culture on the transformed explant; and inducing hairy root generation and hairy root culture proliferation. The formation of glehnia littoralis hairy roots is induced by utilizing the agrobacterium rhizogenes infection, an in-vitro hairy root culture system is established, the content of medicinal component coumarin is analyzed and measured, the content of medicinal component coumarin is contrasted with the content of coumarin in adventitious root and artificially cultured glehnia littoralis roots, the content of coumarin in the hairy roots is the highest, and the glehnia littoralis hairy roots has the advantages of fast growth, short period, relatively high yield of the secondary metabolite and the like and can be used for industrial production of glehnia littoralis coumarin; and moreover, a novel path is provided for industrial production of the secondary metabolite of the glehnia littoralis by utilizing the hairy roots in the future, the threatened plant is protected, and the ecological balance is maintained.

Description

technical field [0001] The invention belongs to the field of plant tissue culture, and in particular relates to a method for inducing proliferation of hairy roots of coral dish. Background technique [0002] Plant tissue culture includes organ culture, callus culture, shoot tip tissue culture, cell culture, protoplast culture, etc. Among them, callus culture is the most common, because except for shoot tip meristem culture and a few organ culture, other types have to go through the callus stage to produce regenerated plants. Formation plays a crucial role in tissue culture technology, and many active ingredients in medicinal plants can be synthesized directly through callus. [0003] Coral vegetable is a perennial herb of the Umbelliferae family that grows on sandy beaches in the coastal areas of the North Pacific Ocean. Distributed in Liaoning, Shandong, Jiangsu and other places in my country, it grows on seashore beaches or is artificially cultivated. It was originally o...
