In vitro plant tissue culture: means for production of biological active compounds
Plant tissue culture has developed widely incorporated into biotechnology, the agricultural systems being a key factor to support many pharmaceutical and industrial outcomes. Since there is vast progress in plant culture and its application has emerged having great diversity in the science filed. Due to development and desire to grow on high scale production in the past few decades, tissue culture techniques were manipulated for improvement of plant growth, biological activities, transformation, and secondary metabolites production. A significant advance in techniques has been sought to deal with problems of low concentrations of secondary metabolites in whole plants. The augmented use of plant culture is due to a superior perceptive of plant oriented compounds and secondary metabolites from economically important plants. Due to development in modern techniques, several particular protocols have been developed for the production of a wide array of secondary metabolites of plants on a commercial scale.
Just as every person is different and unique, so is each plant. Some have traits like better color, yield, or pest resistance. For years, scientists have looked for methods to allow them to make exact copies of these superior individuals. Plants usually reproduce by forming seeds through sexual reproduction. That is, egg cells in the flowers are fertilized by pollen from the stamens of the plants. Each of these sexual cells contains genetic material in the form of DNA. During sexual reproduction, DNA from both parents is combined in new and unpredictable ways, creating unique plants.

Plant tissue culture as an important tool for the continuous production of active compounds including secondary metabolites and engineered molecules. Novel methods gene editing, abiotic stress can improve the technique. Humans have a long history of reliance on plants for a supply of food, shelter and, most importantly, medicine. Current-day pharmaceuticals are typically based on plant-derived metabolites, with new products being discovered constantly. Nevertheless, the consistent and uniform supply of plant pharmaceuticals has often been compromised.
The depicts the sequential fusion of two protoplasts, resulting in a synkaryon. The ensuing hybrid is known as a cytoplasmic hybrid or cybrid. The culture is initially started on a semi-solid medium and the callus so formed is transferred to a liquid medium in an agitated and aerated bioreactor. There are four methods, by which the somatic embryos are transferred to the field. Propagules derived from plant tissue culture exhibit several applications in horticulture, crops, and forestry. This technique is amalgamated with genetic engineering to regenerate plants with novel characters and combine two or more beneficial characters into a single plant.
Use of Tissue Culture for Micropropagation of Vegetable Crops
Tissue culture as a plant production system for horticultural crops pp Cite as. The use of tissue culture with vegetable crops has an extensive history dating back to the classic studies of White 52 and Caplin and Steward 8. As a result of the efforts of many investigators in this area, techniques for micropropagation of most major species of vegetables have been developed. Most of these techniques involve the use of vegetative meristematic tissue; however, methods have also been developed in many crops for regeneration of plants from callus and from protoplasts.
The first and, to date, the most extensive practical application of tissue culture techniques to horticultural crops involves the multiplication of ornarmental plant species. The early work by Morel 4 with orchids, the development of the Murashige and Skoog medium 5 , and the efforts of Murashige 6, 7 to enhance the practical side of tissue culture science stimulated the development and widespread use of tissue culture as a means of micropropagating ornamentals. Herbaceous ornamentals have adapted to tissue culture techniques with relative ease; more attention and efforts have been required to successfully apply in vitro culture techniques to woody plant species.

Tissue culture is the growth of tissues or cells separate from the organism. This is typically facilitated via the use of a liquid, semi-solid, or solid growth medium, such as broth or agar, in vitro under sterile growing conditions. Banana is typically propagated vegetatively; thus tissue culture as a propagation technique provides a robust means to prepare disease-free planting materials that can provide the first line of defense in developing an integrated disease-management program for banana. Tissue-culture techniques established for banana include shoot and meristem culture, callus culture, somatic embryogenesis, cell suspension, and protoplast cultures.
Разные лаборатории приводят разные цифры. ГЛАВА 127 Собравшиеся на подиуме тотчас замолчали, словно наблюдая за солнечным затмением или извержением вулкана - событиями, над которыми у них не было ни малейшей власти. Время, казалось, замедлило свой бег.
- Он похлопал Беккера по спине. - Получите удовольствие, профессор. Вы летали когда-нибудь на Лирджете-60. Беккер усмехнулся: - Давненько не летал.
