Method for determining the action factor of microbial preparations in reducing protein content in tobacco leaves

Abstract

The invention discloses a method for measuring effect factors of a microorganism preparation for reducing the protein content in tobaccos. The method comprises the following steps of: extracting metabolites of a microorganism, performing sodium dodecyl sulfonate (SDS)-preview and graphics editing (PAGE) or dimensional electrophoresis after-cut adhesive tape or digging enzymolysis, and performing liquid chromatography-mass spectrometry / mass spectrometry (LC-MS / MS) analysis on an enzymolysis adhesive tape or a glue point; by multiple comparison treatment, performing chip hybridization on the treated tobaccos, and measuring a gene up-regulation expression and a gene down-regulation expression which are related to plant defense response, endogenous hormone metabolism, cell cycle control and enzyme control. The method has the beneficial effects that metabolic components capable of degrading the proteins in the tobaccos in the microorganism preparation from the molecule level and the change of the gene level of the tobaccos applied with the preparation can be analyzed, so that a mechanism of the microorganism preparation for degrading the proteins in the tobaccos can be comprehensively and clearly defined; theoretical basis is laid for further application of the biological preparation.

Description

technical field [0001] The invention belongs to the field of biochemistry, and relates to a method for detecting the action factors of microbial agents reducing the protein content in tobacco leaves. Background technique [0002] Tobacco leaf, as the main product of tobacco, is not only an important research object as a model plant, but also the main raw material for industry. In my country, the protein content of upper tobacco leaves is relatively high. Protein is an important chemical component of tobacco, and its content is not only very important to the growth process of tobacco, but also closely related to the quality of tobacco. Microorganisms play a very important role in the growth, conditioning, aging, processing and storage of tobacco leaves. In recent years, microorganisms have been widely used to improve the chemical components in tobacco leaves to improve the quality of tobacco leaves. Wang Changguo and others sprayed the microorganisms screened from the soil ...
