Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation .
Micropropagation or tissue culture is the practice of rapidly multiplying plant stock material to produce many progeny plants, using modern plant tissue culture methods. [ 1 ] Micropropagation is used to multiply a wide variety of plants, such as those that have been genetically modified or bred through conventional plant breeding methods.
Thus, in its broader sense, "tissue culture" is often used interchangeably with "cell culture". On the other hand, the strict meaning of "tissue culture" refers to the culturing of tissue pieces, i.e. explant culture. Tissue culture is an important tool for the study of the biology of cells from multicellular organisms.
Tissue culture is an important tool for the study of the biology of cells from multicellular organisms. It provides an in vitro model of the tissue in a well defined environment which can be easily manipulated and analysed. In animal tissue culture, cells may be grown as two-dimensional monolayers (conventional culture) or within fibrous ...
Specialized layer of tissue that allows an organ to be shed by abscission when it is ripe or senescent. Such tissue is commonly formed, for example, at the base of a petiole or pedicel. acaulescent Having no apparent stem, or at least none visible above the ground surface. [2] Examples include some species of Oxalis, [5] Nolina, [6] and Yucca. [7]
A light-dependent reaction was observed in that a decrease in the available CO 2 was found after the light switch in sealed containers used in conventional tissue culture. [2] This led to the idea that plants, even in vitro, are capable of actively producing sugars via photosynthesis and this idea was quickly tested and validated using potato ...
As plants do not have a centralized decision making unit (i.e. a brain), most plants have a decentralized autonomous system in various organs and tissues of the plant. Therefore, they react to multiple stimulus such as light, heat, and humidity. [100] One example is the carnivorous plant species Dionaea muscipula (Venus flytrap). For the last ...
Plant tissue culture allowed new, unique phenotypes and genotypes to be propagated in large numbers quickly. Many cultivars of foliage plants are available only from tissue culture. [ 27 ] Uniquely, tissue cultured geraniums were heat treated to allow the identification and removal of many viruses, virus-indexed. [ 28 ]
