Factory production of new varieties of plants

gene
technology
has shown unprecedented power in the improvement of plant varieties. Among them,
organizations
play an
in the development of technical technology. First, almost all of the genes and their vectors must be imported into
cultured cells
such as
microbial infections or gene guns. The parent cells (
transformational cells) of the successfully obtained gene and its vector were then
method. By inducing and differentiating these transformational cells into individual plants, so-called genetically modified plants can be obtained. Often, the plant-like cells used in GM are from plants that have established a well-established tissue culture and differentiation induction system, so it is not difficult to reproduce these GM plants quickly or even promote their factory production., on the other hand, many of the plant features that need to be improved are not single-gene-determined shapes, and they still need to provide new options through hybrid breeding. In addition to the disadvantages of long plant growth cycles, the main problem encountered in hybrid breeding is the reproductive isolation of distant parents. In fact, this problem can be solved through an organizationally cultivated approach. For example, after removing the embryo beads from the sub-room, they are
the test tube
the test tube. Since there are no barriers to other tissues such as columns, even pollination using distant plants is fine. If we use pre-cultured plant cell protosomes for sophyte fusion, we can also quickly obtain a large number of hybrid cells. The key to the success of the erst means is to find a way to induce the smooth differentiation and reproduction of hybrid protosome cells.addition, pollen cell protosumin culture and chromosomal double technology provides excellent technical means for rapid purification of specific plant line. Purification of plants with a combination of special characteristics usually requires repeated multigenerational planting and screening, a long and arduous process. Because pollen cells are monolithic cells, and chromosomes that double pollen proton cells produce purely combined tumular cells, it is possible for any plant to use this method to quickly obtain the corresponding purity. Many of the new rice product line development is achieved through hybrid rice flower medicine. Moreover, this method is similar to system cell protosome culture and can also be used for the preparation of a large number of hybrid cells. For example, pollen cells that fuse different plants.new varieties, strains and detoxifying plants obtained through the above-mentioned breeding techniques can be reproduced on a large scale using their sethicular or mature tissue
cell culture
techniques. At present, there are many new varieties of flowers, vegetables, fruits and other plants obtained by the above-mentioned methods around the world to achieve a large number of factory, rapid reproduction. For example, citrus, rape, cabbage, etc.
