plant tissue culture techniques and applications

Posted: December 30, 2020 By: Category: Uncategorized Comment: 0

Plant tissue culture is an in-vitro culture or growth of cells, tissues or organs of plant in a sterile condition and well formulated media to produce an entire plant. Plant tissue culture technology is being widely used for large scale plant multiplication. Plant tissue culture (PTC) is a set of techniques for the aseptic culture of cells, tissues, organs and their components under defined physical and chemical conditions in vitro and controlled environment (Fig. Tissue culture had been exploited to create genetic variability, to improve the health of planted material, increase the number of desired germplasm. Or Micropropagation is the technique of multiple production of plants in vitro. Micropropagation is the rapid vegetative propagation of plants under in vitro conditions of high light intensity, controlled temperature, and a defined nutrient medium. Introduction Plant tissue culture is an essential component of plant biotechnology. By using the tissue culture process, a plant's yield can be increased dramatically, and in a short amount of time. An overview of tissue culture techniques and their applications in plant propagation and genetic improvement of plants is presented. Unfortunately, tissue culture is labor intensive, time consuming, and can be costly. The part which is cultured is called explant, i.e., any part of a plant taken out and grown in a test tube, under sterile conditions in special nutrient media.

Advantages of tissue culture over intact plants 1. Plant Tissue Culture is the process of growing isolated plant cells or organs in an artificial nutrient media outside the parent organism.. Application of plant tissue cultures in phytoremediation research: incentives and limitations Biotechnol Bioeng. The method has been popular in agriculture for many years. This technique relies on ‘totipotency’, which means that a part of a plant can give rise to an entire plant when provided with the appropriate growth regulators and environment. Tissue culture techniques are often used for commercial production of plants as well as for plant research. Key parameters for manipulation of plant tissue cultures Sterile techniques Genetic manipulation of crop plants. This definition also extends to the culture of excised embryos and to protoplast culture. Doing this allows them to produce genetically identical clones on a massive scale. Embryo rescue plays an important role in modern plant breeding, allowing the development of many interspecific and intergeneric food and ornamental plant crop hybrids. The plant can also be genetically altered so that it becomes immune to certain diseases and viruses. Plant tissue culture is a straightforward technique and many developing countries have already mastered it. Key targets in agriculture include cereal crops such as maize and wheat. Micropropagation- Stages, Types, Applications, Advantages, Limitations. Its application only requires a sterile workplace, nursery, and green house, and trained manpower. Plant tissue culture involves the culture of all types of plant cells, tissues and organs under aseptic conditions. Plant Tissue Culture (PTC): Definition : Plant tissue culture is a technique with which plant cells, tissues or organs are grown on artificial nutrient medium, either static or liquid, under aseptic and controlled conditions. Plant tissue culture was a new addition to the methods of plant breeding that developed around the 1950s. This technique was not strictly considered as a classical cell and tissue culture, due to grafting tissues and fluids in living animals [52, 53]. 2009 May 1;103(1):60-76. doi: 10.1002/bit.22280. Plant tissue culture is the technique of maintaining and growing aseptically plant cells, tissues or organs on artificial medium in test tube under controlled environmental conditions. Tissue culture involves the use of small pieces of plant tissue (explants) which are cultured in a nutrient medium under sterile conditions. PLANT TISSUE CULTURE 1.1. It makes use of parts of a plant to generate multiple copies of the plant in a very short duration. This is a technique by which new plants can be raised by the use of plant parts or cells. In other words, it is an in vitro culture of plant cells or tissues on an artificial nutrient media under aseptic conditions, in glass containers.. Since the conventional breeding techniques could not fulfil the required demand of crops, tissue culture came around as a grand leap in breeding practices. Cell culture refers to the removal of cells from an animal or plant and their subsequent growth in a favorable artificial environment. In plant cell culture, plant tissues and organs are grown in vitro on artificial media, under aseptic and controlled environment.
