This book provides a general introduction as well as a selected survey of key advances in the fascinating field of plant cell and tissue culture as a tool in biotechnology. After a detailed description of the various basic techniques employed in leading laboratories worldwide, follows an extended account of important applications in, for example, plant propagation, secondary metabolite production and gene technology.

The first method involving the meristems and induction of multiple shoots is the preferred method for the micropropagation industry since the risks of somaclonal variation genetic variation induced in tissue culture are minimal when compared to the other two methods. Living plant materials from the environment are naturally contaminated on their surfaces and sometimes interiors with microorganisms, so their surfaces are sterilized in chemical solutions usually alcohol and sodium or calcium hypochlorite. As shoots emerge from a culture, they may be sliced off and rooted with auxin to produce plantlets which, when mature, can be transferred to potting soil for further growth in the greenhouse as normal plants. Plant tissue culture is used widely in the plant sciences, forestry, and in horticulture. Plant tissue culture is a widely known technique for the production of large numbers of genetically identical plantlets.

Tissue culture

In biological research, tissue culture refers to a method in which fragments of a plant or animal tissue are introduced into a new, artificial environment, where they continue to function or grow. While fragments of a tissue are often used, it is important to note that entire organs are also used for tissue culture purposes. Here, such growth media as broth and agar are used to facilitate the process. Seed culture is the type of tissue culture that is primarily used for plants such as orchids. For this method, explants tissue from the plant are obtained from an in-vitro derived plant and introduced in to an artificial environment, where they get to proliferate. In the event that a plant material is used directly for this process, then it has to be sterilized to prevent tissue damage and ensure optimum regeneration.

Tissue Culture: Methods and Applications presents an overview of the procedures for working with cells in culture and for using them in a wide variety of scientific disciplines. The book discusses primary tissue dissociation; the preparation of primary cultures; cell harvesting; and replicate culture methods. The text also describes protocols on single cell isolations and cloning; perfusion and mass culture techniques; cell propagation on miscellaneous culture supports; and the evaluation of culture dynamics. The recent techniques facilitating microscopic observation of cells; cell hybridization; and virus propagation and assay are also encompassed. The book further tackles the production of hormones and intercellular substances; the diagnosis and understanding of disease; as well as quality control measures. Scientists and professionals interested in methodology per se will find the book invaluable. List of Contributors Preface Section I.

Plant tissue culture media can be used in either liquid or 'solid' forms, depending on the type of culture being grown. Organ cultures are mainly done for highly specialized parasites of certain organs e. They produce exact copies of organisms such as plants required that have desirable traits. The following points highlight the top six types of tissue culture. The types are: 1. This concept was experimentally tested by Haberlandt who gave the idea of culturing plant cells. Explant culture is rarely done.

Tissue Culture

It seems that you're in Germany. We have a dedicated site for Germany. Authors: Mather , Jennie P. This allows topics to be presented with an emphasis on troubleshooting problems from a basis of understanding the underlying theory. The material is presented in a way that is adaptable to student use in formal courses; it also should be functional when used on a daily basis by professional cell culturists in a- demia and industry.

Commercial tissue culture involves exposing plant tissue to a specific regimen of nutrients, hormones, and light under sterile conditions to produce many new plants over a very short period of time. Tissue culture is a biotechnology used in cloning vegetatively propagated plants. In this method, the plant cell is isolated and cultured in an appropriate medium to reform the cell wall and callus.

Solid media are prepared from liquid media with the addition of a gelling agent, usually purified agar.

ПООБЕДАЕМ У АЛЬФРЕДА. В 8 ВЕЧЕРА. В другом конце комнаты Хейл еле слышно засмеялся. Сьюзан взглянула на адресную строку сообщения. FROM: CHALECRYPTO.

Introduction to Cell and Tissue Culture

Затаив дыхание, она вглядывалась в экран. КОД ОШИБКИ 22 Сьюзан вздохнула с облегчением. Это была хорошая весть: проверка показала код ошибки, и это означало, что Следопыт исправен. Вероятно, он отключился в результате какой-то внешней аномалии, которая не должна повториться. Код ошибки 22. Она попыталась вспомнить, что это .

Именно этим принципом вдохновлялся Стратмор, приступая к созданию ТРАНСТЕКСТА. Он недвусмысленно гласит, что если компьютер переберет достаточное количество ключей, то есть математическая гарантия, что он найдет правильный. Безопасность шифра не в том, что нельзя найти ключ, а в том, что у большинства людей для этого нет ни времени, ни необходимого оборудования.

С течением времени это выражение стало означать нечто честное, правдивое. Английское слово sincere, означающее все правдивое и искреннее, произошло от испанского sin сега - без воска. Этот его секрет в действительности не был никакой тайной, он просто подписывал свои письма словом Искренне. Почему-то ему казалось, что этот филологический ребус Сьюзан не обрадует. - Хочу тебя обрадовать.

Какова твоя роль во всем. Сьюзан объяснила, что перехватываемые сообщения обычно исходят от правительств потенциально враждебных стран, политических фракций, террористических групп, многие из которых действуют на территории США. Эти сообщения обычно бывают зашифрованы: на тот случай, если они попадут не в те руки, - а благодаря КОМИНТ это обычно так и происходит. Сьюзан сообщила Дэвиду, что ее работа заключается в изучении шифров, взламывании их ручными методами и передаче расшифрованных сообщений руководству. Но это было не совсем .

Я позвоню и все объясню. Мне в самом деле пора идти, они связи, обещаю. - Дэвид! - крикнула.  - Что… Но было уже поздно. Дэвид положил трубку.

 Больше трех часов. Стратмор кивнул.
