Micropropagation techniques Micropropagation is a simple concept. As a consequence of their presence great economic losses . In vitro methods are usually the methods of choice for large-scale production by the pharmaceutical industry because of the ease of culture for production, compared with use of animals, and because of economic considerations. Tissue culture could be defined as the method of 'in Vitro' culture of plant or animal cells, tissue, or organ on nutrient medium under aseptic conditions usually in a glass container. 1. The in vitro works are carried out in a test tube, dish or flask i.e. . Also, in vitro techniques have been used for micrografting pistachio plants in vitro (Onay et al., 2003; Can et al., 2006). Cell culture is a technique that involves the isolation and maintenance in vitro of cells isolated from tissues or whole organs derived from animals, microbes or plants.

PLANT TISSUE CULTURE Introduction - Tissue culture is in vitro cultivation of plant cell or tissue under aseptic and controlled environment conditions, in liquid or on semisolid well- defined nutrient medium for the production of primary and secondary metabolite or to regenerate plant. Several techniques have been adopted for in vitro plant cell, tissue and organ culture. In vitro culture techniques are now indispensable for the production of disease-free plants, rapid multiplication of rare plant genotypes, plant genome transformation, and production of plant-derived metabolites of important commercial value (see Fig. Callus could also be developed from buds, and root and shoot fragments of about 1.5 mm in size without using nutrient medium. It is also sometimes referred to as 'sterile culture' or 'in vitro culture'. Definition. They reported an improvement in the regeneration frequency, shoot growth, and reduced basal callus formation in regenerated explants. It has applications in The new varieties derived from in vitro tissue culture could exhibit disease resistance and improvement in quality as well as better yield [19]. The in-vitro techniques of mini tomato cv. •The advantages and disadvantages of micropropagation 2. Primary cell culture Growth requirements Primary cells, except for those derived from peripheral blood, are anchorage-dependent, adherent cells, meaning they require a surface in order to grow properly in vitro. For example differentiation, de-differentiation, re-differentiation, regeneration and morphogenesis are terms with overlapping meanings. In vitro assays provide an initial platform for cancer drug discovery approaches. Les techniques de culture in vitro font maintenant partie intégrante des program­ mes d'amélioration des plantes. These techniques are also a starting point for many practical applications that we will briefly present and discuss. 1. La culture de méristèmes : élimination des virus. Microbial contamination is a constant problem, which often compromise development of all in vitro techniques. 3. In vitro culture techniques are now indispensable for the production of disease-free plants, rapid multiplication of rare plant genotypes, plant genome transformation, and production of plant-derived metabolites of important commercial value (see Fig. seaweed tissue culture can be considered as one of the best methods to provide a large amount of seedlings for commercial cultivation. These points are, however, to be carefully assessed before these techniques become a dependable means of plant breeding. The parameters which have been determined to have a significant effect on the growth of in vitro propagated Eucheuma seaweeds are the sterilization techniques, media composition, light intensity and aeration. In Vitro International Pvt. However, the basic techniques of isolation and culture of protoplast are given in Figs. The fertilized egg can then be implanted in the uterus and will attempt to attach and develop inside the female. In this review article, the following biotechnological in vitro culture techniques for virus elimination from ornamental plants are presented: meristem culture, thermotherapy, chemotherapy, cryotherapy or a combination of these methods.

In vitro methods are useful in estimating the fraction of therapeutic compound that might be deposited at the absorption site. Tissue culture is the in vitro aseptic culture of cells, tissues, organs or whole plant under controlled nutritional and environmental conditions [1] often to produce the clones of plants. Seed culture is the type of tissue culture that is primarily used for plants such as orchids. In general, animal cells have more complex nutritional requirements and usually need more stringent conditions for growth and maintenance. In vitro fertilization (IVF) is the process by which a female egg is fertilized outside the body in a laboratory with male sperm, typically in a cell culture dish. In oxygen and nutrients, the gradient can be closely mimicked by 3D cell culture techniques compared to 2D cell culture techniques [1]. Being a large topic area, this review focuses on the biotechnology of cell culture: use of mammalian cells to produce products or the culture of cells as products in their own right. Surface Sterilization of Leaf Samples : Mature leaves are collected from healthy plants which are washed in tap water to remove adhering soil particles and sterilized with sodium hypochlorite solution. Important features of in vitro techniques:- 1. Cell Culture Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of drugs and toxic compounds on the cells, and mutagenesis and carcinogenesis.

Identification 5 Fig. In vitro (Latin: in glass; often not italicized in English usage) studies are conducted using components of an organism that have been isolated from their usual biological surroundings, such as microorganisms, cells, or biological molecules.For example, microorganisms or cells can be studied in artificial culture media, and proteins can be examined in solutions. Tissue culture produces clones, in which all product cells have the same genotype (unless affected by mutation during culture). In some cases, the eggs, sperm or in vitro techniques. depend on a whole range of basic protocols including in vitro maturation (IVM), in vitro fertilization (conventional IVF, parthenogenetic or ICSI) and in vitro culture (IVC) of fertilized oocytes. 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..
