How does micropropagation work?
Micropropagation involves taking small sections of plant tissue, or entire structures such as buds, and culturing them under artificial conditions to regenerate complete plants. Micropropagation is particularly useful for maintaining valuable plants, breeding otherwise difficult-to-breed species (e.g. many trees), speeding up plant breeding and providing abundant plant material for research. For crop and horticultural species, micropropagation is now the basis of a large commercial industry involving hundreds of laboratories around the world. In addition to its rapid propagation advantages, micropropagation can also be used to generate disease-free planting material (Box 7), especially if combined with the use of disease-detection diagnostic kits. There have been some attempts to use micropropagation more widely in forestry. Compared with vegetative propagation through cuttings, the higher multiplication rates available through micropropagation offer a more rapid dissemination of planting stock, although limited availability of desirable clones is an impediment to its wider adoption in forestry.
How are molecular markers used?
Molecular markers have been widely used for identifying genotypes and for “genetic fingerprinting” of organisms . Genetic fingerprinting has been used in advanced tree-breeding programmes in which the correct identification of clones for large-scale propagation programmes is essential. Molecular markers have been used to identify endangered marine species that are either inadvertently captured in wild fisheries or that are purposefully taken illegally. Genotype verification is used intensively in parentage testing of domestic animals and for tracing livestock products in the food chain back to the farm and animal of origin.
How do molecular markers help in genetic conservation?
The use of molecular markers to measure the extent of variation at the genetic level, within and among populations , is of value in guiding genetic conservation activities and in the development of breeding populations in crops, livestock, forestry and fisheries. Studies carried out using these technologies in fish and forest tree species have revealed high levels of genetic variation both among and within populations. Livestock species are characterized by a high degree of genetic variation within populations, whereas crops exhibit a higher degree of variation across species. Data from other approaches, for example field observation, often cannot provide such information or are extremely difficult to collect.
How are genetic linkage maps used?
Genetic linkage maps can be used to locate and select for genes affecting traits of economic importance in plants or animals. The potential benefits of marker-assisted selection (MAS) are greatest for traits that are controlled by many genes, such as fruit yield, wood quality, disease resistance, milk and meat production, or body fat, and that are difficult, time-consuming or expensive to measure. Markers can also be used to increase the speed or efficiency of introducing new genes from one population to another, for example when wishing to introduce genes from wild relatives into modern plant varieties. When the desired trait is found within the same species (such as two varieties of millet – Box 6), it may be transferred with traditional breeding methods, with molecular markers being used to track the desired gene.
What is in vitro selection?
In vitro selection refers to the selection of germplasm by applying specific selection pressure to tissue culture under laboratory conditions. Many recent publications have reported useful correlations between in vitro responses and the expression of desirable field traits for crop plants, most commonly disease resistance. Positive results are available also for tolerance to herbicides, metals, salt and low temperatures. For the selection criteria of major general importance in forest trees (in particular vigour, stem form and wood quality), poor correlations with field responses still limit the usefulness of in vitro selection. However, this method may be of interest in forestry programmes for screening disease resistance and tolerance to salt, frost and drought.
What is the role of biotechnology in the flower industry?
Biotechnology is playing a key role in the generation of new varieties with the change in color, scent, size, and flower through gene manipulation technique. Through biotechnological approaches such as tissue culture and micropropagation techniques, polyploidy induction, mutation, breeding, and genetic engineering. Many varieties of ornamental plants have been developed. More than 50 ornamental plants are now being transformed using Agrobacterium-mediated transformation and particle bombardment techniques. ( Chandler and Sanchez, 2012).

What is marker assisted selection?
Marker-assisted selection or molecular breeding is cutting edge technology among today’s biotech companies. Plant breeders can use this technique to locate and assemble desirable traits to speed up the process of developing the new commercial hybrids.
What do the red index cards stand for?
Tell students that the red index cards stand for vitamin B production, the green index cards for drought tolerance , and the yellow index cards for disease resistance. The cards with stars represent alleles with favorable traits. Scientists want to combine all three favorable traits in one new strain of rice. They will accomplish this through selective breeding.
How many index cards per student?
Make sure there are at least two index cards of each color per student (for a total of six index cards per student). Randomly place a star on one-fourth of the red, green, and yellow index cards. Mix all the cards together with the stars facing down. Then have each student choose two index cards of each color.
What does the new hand of cards represent?
The new hand of cards represents the genotype of the new strain of rice. Have students repeat the card exchange with other partners until someone has a hand where all the cards have stars. This represents a strain of rice that possesses all the favorable traits.
How to model selective breeding?
To model the process of selective breeding, have each student select a partner (they can tell each other what gene cards they have). They should place their cards face down on a table so they cannot see the stars. They should then mix the cards together, and each student should draw two red, two green, and two yellow cards from the pile. The new hand of cards represents the genotype of the new strain of rice.
What is the impact of cloning on farming?
Impact of Cloning on Farming. Cloning is often a science fiction plot point. In the Star Wars movies, cloned humans were used as soldiers in battle. In Jurassic Park, cloned dinosaurs were used to populate a theme park.

How does gene therapy work?
In its simplest form, it involves the introduction of a non-mutated gene at a random location in the genome to cure a disease by replacing a protein that may be absent in these individuals because of a genetic mutation . The non-mutated gene is usually introduced into diseased cells as part of a vector transmitted by a virus, such as an adenovirus, that can infect the host cell and deliver the foreign DNA into the genome of the targeted cell ( Figure 10.8 ). To date, gene therapies have been primarily experimental procedures in humans. A few of these experimental treatments have been successful, but the methods may be important in the future as the factors limiting its success are resolved.
What is the purpose of a weakened or inactive form of microorganisms or viruses?
Traditional vaccination strategies use weakened or inactive forms of microorganisms or viruses to stimulate the immune system. Modern techniques use specific genes of microorganisms cloned into vectors and mass-produced in bacteria to make large quantities of specific substances to stimulate the immune system. The substance is then used as a vaccine. In some cases, such as the H1N1 flu vaccine, genes cloned from the virus have been used to combat the constantly changing strains of this virus.
