Embodiment 1

[0042] This example provides the cloning method of SoCHS gene.

[0043] S11, extraction of total RNA from Lilac chinensis

[0044] The North China lilac materials used in the present invention are all collected from the Forest Germplasm Resource Nursery of Beijing Agricultural College, a resource preservation unit of the National Forest Germplasm Resource Platform (NFGRP). Select 10 North China lilacs that grow well and are free from diseases and insect pests, and collect plant materials from four directions in the southeast, northwest, and east.

[0045] According to the whole gold RNA extraction kit (TransZol TM Total RNA was extracted according to the instructions of Up Plus RNA Kit. Use 1.2% concentration of agarose to detect the integrity of RNA, use a UV spectrophotometer to measure the absorbance of RNA at 230nm, 260nm and 280nm wavelengths, and determine the concentration and purity of RNA

Abstract

The invention relates to the technical field of biology, and concretely relates to a syringa oblate chalcone synthase gene. According to the invention, an Unigene sequence fragment of chalcone synthase gene (SoCHS) obtaining by syringa oblate transcriptome sequencing is taken as a template, a SoCHS cDNA full length sequence is obtained; based on bioinformatics analysis on a structure and coding protein, a molecular biology technology is used, an overexpression and YFP positioning expression carrier of the gene is constructed, through agrobacterium mediation, arabidopis thaliana and tobacco are converted, the protein characteristic is analyzed and the function is verified; and a RT-PCR technology is used for analyzing the tissue specific expression mode of the gene. A molecule mechanism formed by SoCHS-participated pattern control is researched and revealed.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a chalcone synthase gene from Lilac chinensis and application thereof. Background technique [0002] Flower color is one of the important ornamental characteristics of garden plants, and flavonoids and their colored derivatives play an extremely important role in the formation of flower color. Chalcone synthase (CHS) is a key enzyme in the metabolic synthesis pathway of flavonoids, which catalyzes the conversion of one molecule of Coumanyl CoA (Coumanyl CoA) and three molecules of malonyl CoA (Malonyl CoA). CoA) generates 4,5,7-trihydroxyflavanone (Narigenin chalcone). In higher plants, flavonoids are secondary metabolites that widely exist and play an important role in the interaction between plants and the environment. They not only play a decisive role in the formation of plant flower colors, but also participate in various physiological processes of plants. Biochemical processe...
