Is there a way for plant tissue culture technicians to develop money? What is the process of development?

Is there a way for plant tissue culture technicians to develop money? What is the process of development? 1 Lou's answer is too idealistic.

If you really want to engage in this profession, it is to organize a culture laboratory, prepare drugs, cut seedlings, cultivate, observe ~ ~ and then mix and cut. ...

Besides, we have to go to the wild or the destination to get the wild seedlings back for domestication.

In a word, that's what I used to do. I basically have no money, unless you are a professional, and then you are a professor at the school. You can send a paper, do it well, win a prize, be famous, and you will have money. My tutor is like this. He won the prize of 100W before he published a paper. Of course, he can't have won it himself ~ ~ If he is just an experimenter, then he really has no future and no money.

In China, many occupations are too idealistic, which is very inconsistent with reality. For example, if I study biotechnology, can I really engage in genetic engineering research after graduation What other majors, such as industrial engineering, thermal engineering and employment, are difficult to link with ideals?

Finally, my suggestion is: if you just graduated and need a job, it's good that the job doesn't have to be exposed to the wind and the sun. If you really want to make achievements in this field and get a title, you can do it, but if you just want money or you may not do it at any time, forget it. There is no money in this job.

With the rapid development of science and technology, plant tissue culture technology has entered the stage of production and application. The picture shows a schematic diagram of plant tissue culture process, please follow the requirements (1). The advantages of tissue culture are: a large number of new plants can be cultivated in a short time; It can also prevent the harm of plant viruses and greatly improve the efficiency of agricultural production.

(2) Plant tissue culture refers to cutting the stem tips, stem segments or leaves of plants into small pieces under aseptic conditions, culturing them on special culture medium, and gradually developing into complete plants through cell proliferation and differentiation.

So the answer is: (1) cultivate a large number of new plants in a short time; Prevent the harm of plant viruses and greatly improve the efficiency of agricultural production;

(2) Sterile conditions.

With the rapid development of science and technology, plant tissue culture technology has been widely used in production practice.

Plant tissue culture is a kind of asexual reproduction, which cannot change the maternal traits, but virus-free tissue culture seedlings can be cultivated through virus-free stem tips.

Is it necessary to adopt plant tissue culture technology in colchicine haploid breeding? Because chromosomes can't join normally during meiosis of haploid plants, they can only be cultured in plant tissues. Treating seedlings with colchicine to form normal polyploid plants.

Plant tissue culture technology has not studied how to write rooting method.

Plant tissue culture refers to the process of culturing isolated plant cells, tissues or organs into complete plants through specific culture. Therefore, in vitro culture of anthers, the culture of recipient cells in genetic engineering, the culture of hybrid cells after somatic hybridization and the rapid propagation of plants all require plant tissue culture technology. The process of plant tissue culture is that explants dedifferentiate callus, and then differentiate into roots, buds and test-tube seedlings. The material of virus-free seedlings is usually buds or stems, mainly because these parts are virus-free. In the process of plant tissue culture, when auxin and cytokinin are used at the same time, the ratio of their dosage affects the development direction (or differentiation) of cells. Cultures must contain phytohormones, inorganic substances (mineral elements), organic substances and other nutrients. Callus is characterized by loose and irregular cell arrangement and amorphous state.

Is plant tissue culture biotechnology? Yes, it belongs to plant cell engineering.

Since 1958, the phloem cells of carrot have been cultured into complete plants, and the plant tissue culture technology has developed to modern times, which has been widely used in flower cultivation, crop breeding, biopharmaceuticals and so on.

Both haploid and polyploid breeding processes need plant tissue culture technology? Haploid breeding refers to the induction of haploid plants by plant tissue culture techniques (such as in vitro culture of floral medicine, etc.) ), and then by some means (such as colchicine treatment) to double the genome, restore the normal chromosome number of plants. Haploid is a biological individual whose somatic chromosome number is the gamete chromosome number of this species. Polyploid refers to an individual with three or more chromosomes in somatic cells. The most commonly used and effective polyploid breeding method is to treat germinated seeds or seedlings with colchicine or low temperature induction. Colchicine can inhibit the formation of spindle during cell mitosis, but it does not affect chromosome replication, so that cells cannot form two daughter cells, but the number of staining is doubled. Therefore, when the cell divides again, the chromosomes in the cell will double. Mutation breeding refers to the breeding method of inducing the genetic characteristics of animals and plants to mutate through physical and chemical factors, and then selecting individual plants/individuals that meet people's certain requirements from the mutated population, and then cultivating new varieties or germplasm. Cross breeding refers to the method of crossing individuals of different populations and genotypes, and cultivating homozygous varieties through selection in their hybrid offspring. Hybridization can make parents' genes recombine and form various types, providing rich materials for selection; Gene recombination can combine excellent genes whose parents control different traits, and can also accumulate different minor genes whose parents control the same trait, resulting in types whose traits are superior to those of their parents. Among them, haploid breeding and polyploid breeding are mutation breeding with chemical substances to form chromosome multiples different from normal plants. However, cross breeding only artificially narrowed the geographical isolation of the two populations, and did not change the chromosome number and gene composition of this species. Mutant individuals in mutation breeding appear in this generation, while performance plants in cross breeding generally appear in the next generation.

Haploid breeding usually adopts anther culture in vitro, which is a necessary process. There is no need for polyploid breeding, such as seedless watermelon cultivation, and the whole process does not use plant tissue culture technology, but uses chromosome variation. First, the chromosome is doubled with colchicine to obtain tetraploid, and then the tetraploid plant is crossed with diploid plant to obtain triploid plant which can not produce seeds, and it is completed.
