How tissue culture is used to conserve rare and endangered plants?

TISSUE CULTURE- Introduction Plant tissue culture is the culture and maintenance of plant cells or organs in sterile, nutritionally and environmentally supportive conditions (in vitro). Plant cell and tissue culture include the cultural techniques for regeneration of functional plants from embryonic tissues, tissue fragments, calli, isolated cells, or protoplasts. It has applications in research and commerce. In commercial settings, tissue culture is often referred to as micro-propagation, which is in fact one of the techniques in tissue culture. Micro-propagation refers to the production of whole plants from cell cultures derived from explants (the initial piece of tissue put into culture) or meristem cells. The success for plant tissue culture is based on the principle called totipotency - the ability of undifferentiated plant tissues to differentiate into functional plants when cultured in vitro. Plant tissue culture is used widely in plant science; it also has a number of commercial applications. Applications include: Micro-propagation is widely used in forestry and in floriculture. Micro-propagation can also be used to conserve rare or endangered plant species. Micropropagation and cryopreservation are tools with multiple applications and benefits within an integrated plant conservation research program. CREW's Endangered Plant Propagation Program has adapted and applied these methods to a broad range of endangered U.S. species, in collaboration with a number of U.S. botanical gardens within the Center for Plant Conservation network. In vitro methods are developed for species for which traditional methods of propagation are not adequate. In addition to standard tissue culture propagation, techniques for in vitro germination and in vitro collecting can be used to initiate shoot forming cultures, while in vitro rooting may overcome specific problems encountered with traditional rooting methods. Micropropagation can also alleviate stress on the in situ population by providing plants for lab/greenhouse research, education, reintroduction, augmentation or the establishment of new populations for field research. Horticultural expertise is important for the successful acclimation of micropropagated plants for these uses. Cryopreservation banking for long-term germplasm storage can be applied to a variety of propagules, including seeds, embryos, spores, pollen, gametophytes, shoot tips, and embryogenic callus cultures. No one technique will be applicable to every endangered plant, and examples of all of these are in CREW's liquid nitrogen storage facility, or 'Frozen Garden'. In addition to long-term storage of rare germplasm, cryopreservation can also help overcome specific problems: species with seeds or embryos that are short-lived or which have recalcitrant seeds; species that are not producing many viable seeds; species for which in vitro propagation protocols have been developed, but for which no habitat is presently suited for reintroduction. Each species presents a unique opportunity to draw from the variety of micropropagation and cryopreservation methods in order to develop techniques to address its specific conservation challenges.

What is the significance of Jem's name?

There is no significance with Jem's name, its just short for Jeremy :)

What must true for a cross between a tall plant and a short plant to produce any short plants?

the tall plant must be heterozygous.

When gregor mendel crossed a tall plant with a short plant the F1 plant inherited what?

one tall allele and one short allele

What must br true for a cross between a tall plant and a short plant to produce any short plants?

The tall plant must be heterozygous.

What are some characteristics of a short plant with flowers?

short with flowers

What are the methods of natural vegetative propagation with benefits?

Natural vegetative propagation is a method of asexual reproduction in plants which involves the use of an existing part of a plant to generate a new individual. There are several methods of natural vegetative propagation including budding layering cutting and division each of which has its own benefits. Budding is a method of vegetative propagation in which a new plant is created from a bud on the stem of the parent plant. This method is often used to propagate plants such as roses grapes and fruit trees. The benefit of this method is that it is relatively quick easy and reliable. Layering is a method of vegetative propagation in which a branch of the parent plant is bent to the ground and covered with soil. The branch will eventually root and can be separated from the parent plant. This method is used to propagate plants such as blackberries and raspberries. The benefit of layering is that it is simple and reliable. Cutting is a method of vegetative propagation in which parts of the parent plant such as stems leaves and roots are cut and planted in soil. This method is often used to propagate plants such as African violets and coleus. The benefit of cutting is that it is fast simple and reliable. Division is a method of vegetative propagation in which the parent plant is divided into smaller sections and each section is planted in soil. This method is often used to propagate plants such as lilies and daffodils. The benefit of division is that it is relatively easy and reliable. These methods of natural vegetative propagation each have their own benefits and can be used to propagate a variety of plants.

In pea plants the allele for tallness is dominant. What are the possible genotypes of a tall pea plant?

the tall plant must be heterozygous

What has the author Ralph J Slutz written?

What is the significance of the RSGD algorithm in machine learning optimization techniques?

The RSGD algorithm, short for Randomized Stochastic Gradient Descent, is significant in machine learning optimization techniques because it efficiently finds the minimum of a function by using random sampling and gradient descent. This helps in training machine learning models faster and more effectively, especially with large datasets.

When Gregor Mendel crossed a tall plant with a short plant what where the results of the F1 generation?

The F1 generation of crossing a tall plant with a short plant resulted in all tall plants. This is because the tall trait is dominant and the short trait is recessive in Mendel's experiments with pea plants.
