Description

Culture medium for improving cell division frequency of dendrobium officinale protoplast
Technical Field
The invention relates to a culture medium for improving the cell division frequency of a dendrobium officinale protoplast, belonging to the field of plant cell engineering.
Background
Dendrobium officinale (academic name:Dendrobium officinalekimura et Migo) is a herbal plant of Dendrobium (Dendrobium) of Orchidaceae (Orchidaceae), naturally grows on cliff or big trees, and is mainly distributed in Anhui, Zhejiang, Hunan, Jiangxi, Fujian, Guangdong, Guangxi, Yunnan and other areas in China, so that wild germplasm resources are wide in distribution range and large in area. The dendrobium officinale is a traditional and rare Chinese medicinal material in China, is listed as the head of the nine-large Chinese mesona in the channel storage, and has the effects of nourishing yin, promoting the production of body fluid, moistening throat, protecting throat, warming stomach, improving eyesight, tonifying kidney, benefiting strength, prolonging life and the like. According to the record of 2010 version pharmacopoeia, dendrobium officinale is sweet in nature and taste, slightly cold, enters stomach and kidney channels, benefits stomach, promotes fluid production, nourishes yin and clears heat. Can be used for treating fever with body fluid deficiency, dry mouth, polydipsia, stomach yin deficiency, poor appetite, vomiting, persistent asthenic fever after illness, yin deficiency, hyperactivity of fire, bone steaming, overstrain, dim and poor vision, and flaccidity of tendons and bones. Preparation of Dendrobium officinaleThe main effective components are dendrobium polysaccharides, alkaloids, phenols, amino acids and the like, and modern medical research shows that the dendrobium officinale has the effects of resisting tumors and aging, enhancing the immunity of the organism, reducing blood sugar, effectively relieving liver injury and the like. With the improvement of living standard and the increase of health care consciousness of people, the medicinal value of the dendrobium officinale is gradually accepted by the public and the market is in short supply. At present, the tissue culture technology is mature day by day, and the dendrobium officinale can realize large-scale propagation by an industrial tissue culture method. However, the dendrobium officinale has a lot of wild resources and good and uneven quality, and the development of the dendrobium officinale industry is slow due to the unclear breeding target, the lagged research on breeding technology and the lack of good and characteristic new varieties of dendrobium officinale in the market.
Plant protoplasts refer to the part of a cell that is left bare or surrounded by a plasma membrane after removal of the plant cell wall. The research on plant protoplasts dates back to 60 th of the 20 th century, and British phytologists Cocking degraded cell walls by an enzymolysis method to obtain tomato root tip protoplasts. In 1970, Nagata and Table report that tobacco mesophyll protoplasts are separated and cultured to obtain regenerated plants for the first time, and then more and more plastid regenerated plants are successful, and the research types are continuously increased, including forest trees, ornamental plants, medicinal plants, fruit trees and crops. Protoplasts have particular advantages because they lose the cell wall barrier. Protoplasts can provide good experimental materials for cell biology, developmental biology, cell physiology, cytogenetics and other biological subjects; the exchange of genetic materials can be solved at a cell level by the biomass culture and cell fusion, and excellent genetic characters of the plant kingdom are widely recombined by the fusion of heterologous protoplasts, so that a new way is opened up for plant breeding; protoplasts can directly take exogenous DNA, organelles, viruses, plasmids and the like, and are ideal receptors for genetic transformation research. Therefore, plant protoplasts have a wide range of applications in modifying plant genetics, improving crop varieties, and basic theory of biology.
Obtaining a large amount of complete and viable protoplasts is the primary condition for the success of protoplast culture. The enzymolysis separation method is a protoplast separation method which is generally adopted at present. The selection of plant material, the pretreatment process, the use of enzyme preparations, etc., all can affect the separation effect of protoplasts. Among dendrobium plants, methods for separating protoplasts of dendrobium officinale, dendrobium huoshanense, dendrobium nobile and the like have been reported, and the protoplasts can be obtained more effectively.
The protoplast after separation and purification can be cultured under a proper culture medium and culture conditions to regenerate a new cell wall, then the cell can be cracked, and further a new cell mass and callus can be formed, and finally the plant can be regenerated from the callus through an organogenesis way or an embryoid way. Protoplast culture is also affected by a number of factors, including the plant material genotype, the initial density of the protoplast culture, the culture medium, the culture method, the concentration of osmostabilizers, hormones, light, temperature, and other environmental factors. At present, the culture result of the dendrobium plant protoplast is generally poor, the best result is that a cell mass is formed only after several divisions, the cell mass forming frequency is extremely low, and callus or embryoid is difficult to further form. Therefore, on the basis of the predecessors, the cultivation research of the dendrobium officinale protoplast is developed, the bottleneck problem encountered by the predecessors is hoped to be solved, the division frequency of the dendrobium officinale protoplast is improved, and a foundation is laid for establishing the researches of fusion of the dendrobium officinale protoplast, genetic transformation and the like.

Influence of certain components in protoplast culture medium on culturing of dendrobium officinale protoplast
1. Influence of Dendrobium officinale leach liquor concentration on protoplast culture
Under the condition that other components are not changed, the protoplast culture media with the concentrations of the dendrobium officinale leaching liquor being 20, 40, 60 and 80ml/L are respectively prepared, the protoplast culture media without the dendrobium officinale leaching liquor is used as a control group, then the liquid shallow layer static culture is carried out on the dendrobium officinale protoplast according to the method, and the results are shown in table 1.
Figure DEST_PATH_IMAGE001
As can be seen from Table 1, compared with the control group, the addition of the leaching solution of Dendrobium officinale with the tested concentration can increase the cell division frequency and the cell cluster formation frequency of the protoplast of Dendrobium officinale, when the concentration of the leaching solution of Dendrobium officinale is 40ml/L, the cell division frequency reaches 27.64%, the cell cluster formation frequency reaches 5.99%, which are the highest values, and when the concentration of the leaching solution of Dendrobium officinale exceeds 40ml/L, the cell division frequency and the cell cluster formation frequency show a decreasing trend. The addition of the leaching solution of Dendrobium officinale Kimura et Migo can increase the division frequency of the protoplast cells of Dendrobium officinale Kimura et Migo probably because it can provide other natural nutrients required by the growth and division of the protoplast, and some components of the leaching solution can not be provided or are not provided by artificial culture medium.
2. Effect of sodium butyrate concentration on protoplast culture
Under the condition that other components are not changed, protoplast culture media with sodium butyrate concentrations of 0.5, 1.0, 2.0 and 5.0mmol/L are respectively prepared, the protoplast culture media without sodium butyrate are used as a control group, and then the dendrobium officinale protoplast is subjected to liquid shallow layer standing culture according to the method, and the results are shown in table 2.
Figure DEST_PATH_IMAGE002
As can be seen from Table 2, compared with the control group, the addition of the sodium butyrate with the test concentration can promote the cell division of the protoplast of the dendrobium officinale, the culture effect is the best when the concentration of the sodium butyrate is 2.0mmol/L, the cell division frequency can reach 28.40%, and the cell mass formation frequency can reach 6.07%, which are the highest values.
Effect of 3.5-Aminolevulinic acid concentration on protoplast culture
Under the condition that other components are not changed, protoplast culture media with the concentrations of 5-aminolevulinic acid of 0.01, 0.05, 0.1 and 0.5mg/L are respectively prepared, the protoplast culture media without adding 5-aminolevulinic acid are used as a control group, and then the liquid shallow layer standing culture is carried out on the dendrobium officinale protoplast according to the method, and the results are shown in table 3.
Figure DEST_PATH_IMAGE003
As can be seen from Table 3, the effect of 5-aminolevulinic acid on the culture effect of the dendrobium officinale protoplast is remarkably influenced, the culture effect is best when the concentration of 5-aminolevulinic acid is 0.05mg/L, the cell division frequency can reach 28.17%, the cell mass formation frequency can reach 6.10%, and the highest values are obtained. As the concentration of the 5-aminolevulinic acid continues to increase, the cell division frequency and the cell mass formation frequency of the protoplast inversely decrease, and when the concentration of the 5-aminolevulinic acid is 0.5mg/L, the cell division frequency and the cell mass formation frequency are lower than those of a control group, which indicates that the 5-aminolevulinic acid with too high concentration is not beneficial to the growth and division of the dendrobium officinale protoplast.
4. Effect of different media on protoplast culture
The protoplast culture medium of the invention and the protoplast culture medium of the prior art are respectively adopted to carry out liquid shallow layer static culture on the dendrobium officinale protoplast according to the method, thereby comparing the influence of different culture media on the protoplast culture, and the results are shown in table 4.
A protoplast culture medium in the prior art consists of the following components: 1/10MS (1/10 of MS as macroelements and iron salts, unchanged other components), NaH2PO4150mg/L,CaCl2111mg/L,KH2PO4100mg/L, 150mg/L of asparagine, 150mg/L of glutamine, 200mg/L of arginine, 2mg/L of glycine, 250mg/L of hydrolyzed milk protein, 50mg/L of ascorbic acid, 50mg/L of glutathione, 0.10% MES, NAA2mg/L, 6-BA0.5mg/L, 0.06mol/L of sucrose and 0.44mol/L of mannitol. The culture medium is derived from Zhanzhong root, xu process, Zhangming, and the separation and culture research of the dendrobium officinale mesophyll protoplast.
Figure DEST_PATH_IMAGE004
As can be seen from Table 4, after the protoplast culture medium of the invention is adopted for culture, the cell division frequency of the dendrobium officinale protoplast can reach 28.35 percent, which is 2.6 times of that of the prior art, and the cell mass formation frequency can reach 6.12 percent, which is 6.8 times of that of the prior art, and is remarkably improved. The protoplast culture is influenced by various factors such as the type of culture medium, the culture mode, the density of the protoplasts, exogenous growth regulators and the like, and the type of the culture medium is a key factor influencing the culture effect of the protoplasts. Among the components of the medium, inorganic salts are the main constituent, and among them, calcium salts and ammonium salts have a large influence on the culture of protoplasts. The culture medium of the invention adjusts the concentration of each inorganic salt component, especially the concentration of calcium salt and ammonium salt, on the basis of the conventional culture medium, thereby improving the stability of protoplast and reducing death. The combination of 2,4-D, NAA and 6-BA is selected in the aspect of plant growth regulator, and the optimal concentration ratio is screened. In addition, the culture medium is also added with rhamnose, cellobiose, ribose, sodium selenite, L-carnitine, 5-aminolevulinic acid, sodium butyrate, dendrobium officinale leaching liquor, corn juice and the like, which can be used as precursor substances for cell wall synthesis, induction factors for promoting cell division and the like, and the culture effect of the dendrobium officinale protoplast is obviously influenced, so that the cell division frequency and the cell mass formation frequency are obviously improved.
