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. Different techniques in plant tissue culture may offer certain advantages over traditional methods of propagation, including:. Plant tissue culture relies on the fact that many plant cells have the ability to regenerate a whole plant totipotency. Single cells, plant cells without cell walls protoplasts , pieces of leaves, stems or roots can often be used to generate a new plant on culture media given the required nutrients and plant hormones. Preparation of plant tissue for tissue culture is performed under aseptic conditions under HEPA filtered air provided by a laminar flow cabinet. Thereafter, the tissue is grown in sterile containers, such as Petri dishes or flasks in a growth room with controlled temperature and light intensity.
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. Embryo culture is the type of tissue culture that involves the isolation of an embryo from a given organism for in vitro growth.
In addition, plant tissue culture is considered to be the most efficient technology for crop improvement by the production of somaclonal and gametoclonal variants. Plant tissue in small amounts is sufficient for the production of millions of clones in a year using micropropagation. Advantages of Plant cell, Tissue and organ culture as source of secondary metabolites; Hairy Root cultures; Screening of High yielding cell lines and extraction of High value Industrial Products; Fractionation and Bioassays of plant extract Plant tissue culture technology is being widely used for large scale plant multiplication. It refers to a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of the known composition.

This journal highlights the myriad breakthrough technologies and discoveries in plant biology and biotechnology. The journal also covers practical and applied plant biotechnology, including regeneration, organogenesis and somatic embryogenesis, gene transfer, gene flow, secondary metabolites, metabolic engineering, and impact of transgene s dissemination into managed and unmanaged plant systems. PCTOC: Journal of Plant Biotechnology features scientific articles that detail novel discoveries, mini-reviews, original articles, research notes, and original methods. Issue 3, March As a result of the significant disruption that is being caused by the COVID pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times. Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time.

Significant advances in plant cell, tissue and organ culture PCTOC have been made in the last five decades. PCTOC is now thought to be the underlying technique for understanding general or specific biological functions of the plant kingdom, and it is one of the most flexible foundations for morphological, physiological and molecular biological applications of plants. Furthermore, the recent advances in the field of information technology IT have enabled access to a large amount of information regarding all aspects of plant biology.

Беккер зашагал по комнате. - На руке умершего было золотое кольцо.
Подумайте, - продолжал настаивать Беккер. - Очень важно, чтобы досье консульства было как можно более полным. Мне нужно подтвердить ваш рассказ заявлениями других свидетелей. Необходима любая информация, которая поможет мне их разыскать. Но Клушар не слушал. Он вытирал лоб простыней. - Простите… может быть, завтра… - Его явно мутило.
ГЛАВА 120 Шеф отдела обеспечения системной безопасности, тучный мужчина весом за центнер, стоял неподвижно, заложив руки за голову. Он не мог поверить, что дожил до подобной катастрофы. Он отдал распоряжение вырубить электропитание, но это все равно произойдет на двадцать минут позже, чем следует.

Оказавшись наконец в шифровалке, Сьюзан почувствовала, как на нее волнами накатывает прохладный воздух. Ее белая блузка промокла насквозь и прилипла к телу. Было темно.
Невзламываемый шифр. Но это полный абсурд. Неужели Хейл никогда не слышал о принципе Бергофского. - Вот что нам надо сделать.
Беккер понимал, что, по мнению бармена, ведет себя странно. - Quiere Vd.
