Cultures taken from meristematic tissue are usually virus free 2. Contamination can also spread from culture to culture. Mitigating Risks of commercial plant tissue culture The utilization of plant tissue culture for commercial production is limited by two major risks viz., spread of diseases especially those caused by viruses, and variations. This is a technique by which new plants can be raised by the use of plant parts or cells. The initial plant material is cultured and developed in a specific and tightly controlled environment. Thousands of plantlets can be produced in a few weeks time from a small amount of plant tissue. Tissue culture is a very fast technique. 2. 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. The essential point as far as plant cell culture is concerned is that, due to this plasticity and totipotency, specific media manipulations canbe used to direct the development of plant cells in culture.

Agar---a polysaccharide … In a broad sense, the term "plant tissue cultu re" denotes collectively the in vitro culture of plant cells, protoplasts, tissues and organs. Cell culture refers to the removal of cells from an animal or plant and their subsequent growth in a favorable artificial environment. ABSTRACT Plant tissue culture refers to growing and multiplication of cells, tissues and organs of plants on defined solid or liquid media under aseptic and controlled environment. The basic concepts of tissue culture were formulated early . Tissue culture is the culture and maintenance of plant cells or organs in sterile, nutritionally and environmentally supportive conditions (in vitro). Plant tissue culture is now a well-established technology. Various changes taking place in a cell can be noted from clonal culture. Tissue culture techniques are also used to grow plant and animal cells that have been genetically modified in the laboratory. Tissue culture is the in vitro aseptic culture of cells, tissues, organs or whole plant under controlled nutritional and environmental conditions [] often to produce the clones of plants.The resultant clones are true-to type of the selected genotype. Thousands of plantlets can be produced in a few weeks time from a small amount of plant tissue. [9] In particular, the technology is useful for reducing plant breeding times or creating large amounts of plant material for research or distribution to farmers especially for crops important to food security in developing countries.

Commercial tissue-culture laboratories are generally equipped with laminar flow hoods and autoclaves, and they operate using sterile techniques. Tissue culture is the culture and maintenance of plant cells or organs in sterile, nutritionally and environmentally supportive conditions (in vitro). All tissue cultures start life as a small cutting from a sample. Micropropagation is a method to produce genetically identical plantlets by using tissue culture techniques. PDF | On Apr 1, 2014, B O Ehirim and others published ACCLIMATIZATION: AN IMPORTANT STAGE IN TISSUE CULTURE. Tissue culture techniques are also used to grow plant and animal cells that have been genetically modified in the laboratory. Tissue culture has great importance in studies of plant morphogenesis, physiology, biochemistry, pathology, embryology, cytology etc. Tissue culture is seen as an important technology for developing countries for the production of disease-free, high quality planting material and the rapid production of many uniform plants. Cell culture techniques pro-vide scientists a rapid means of screening genetically modified Advantages of Tissue Culture 1. Tissue culture is a very fast technique. Once cleaned, the plant tissue goes in a dense nutrient culture which is typically an agar gel containing a carefully crafted nutrient, hormone and sugar mixture. stream ;��q�r�S�1��lu��BN맛��^m�C��~��h0By !��KCЃ�{�|B��$��FwJjc׿$�NM�瑛��6��ND^�^"MLm�B�G��9��7[EX�u�a �hZ��_ӮJ�I��|��]�aC�0` �W�v��Gfʦx��4�u��ё��S��"_@��b�f��:{3�V $��fp�Ӹ>��\"�~�p�)JӋ��D�L�}j��S�Ӎ��ˌ��?�j��O"��S@��VX�*�Zo @3�C�j>��I��z�dێ^��A��6�l�n�N(e׿'Lvԓ\��g�[E#�ի��/��)�8��f擱��U�D�� C��N��N�w�- �F �E��`f& �g}3�4j�`�89n�-b:��^ z��[��㣟��q��5+3��>�=?H�r+�r[�VNt�Fm�1]Om�vj{��G��+h��g2� Ww�:��_-,l��=w�b��D��f��ΨI�e��ܤ�E��^Ϛ� Fm`k�q�&Lxd(��#a��NϘe�?��ЗӼ5�5Bj�և�iC�b��އNޤh��8X��!��p|Jh/��q�� HF8)5��[z��a�QNUg�,��HP�!G�h֧��3+��Q?��ާ��\v�`�WN�)R�^�x_�FҮ&��p.��(��ĝ*Ԓ�N8 �1x�w��a.

It is important to use tissue or plant cells in a suitable culture medium quality mother plant stock to initiate cultures[2]. Like many other technologies, it has gone through different stages of evolution; scientific curiosity, research tool, novel applications and mass exploitation. Cell culture … Using the appropriate growing conditions for each explant type, plants can be induced to rapidly produce new shoots, and, with the addition of suitable hormones new roots. In most cases the microorganisms outgrow the plant tissues, resulting in their death.

It is widely used to produce clones of a plant in a method known as micropropagation. Plant tissue culture is a technique that has been around for more than 30 years. Plant Tissue Culture is the process of growing isolated plant cells or organs in an artificial nutrient media outside the parent organism.. Tissue culture is used to develop thousands of genetically identical plants from one single parent plant known as soma clones, and this process is known as micropropagation. Otherwise known as micropropagation, the Tissue Culture Process helps you to grow multiple uniform plants in quick succession. The controlled conditions provide the culture an environment conducive for their growth and multiplication. The in vitro environment in which the plant material is grown is also ideal for the proliferation of microorganisms. Micropropagation techniques are of three types based on the way of propagation: first, the propagation from shoots with cytokinin like benzyladenine or kinetin; second, multiple shoot differentiation from dedifferentiating tissue, callus, with an auxin-like indole acetic acid; and finally, the embryo differentiation from callus.
