How does somatic hybridization work?
Somatic hybridization removes the cell walls of cells from different organisms and induces the direct mixing of DNA from the treated cells, which are then regenerated into whole organisms through tissue culture. Marker-aided genetic analysis studies DNA sequences to identify genes, QTLs (quantitative trait loci), and other molecular markers and to associate them with organism functions, i.e., gene identification. Marker-aided selection is the identification and inheritance tracing of previously identified DNA fragments through a series of generations. Genomics analyzes whole genomes of species together with other biological data about the species to understand what DNA confers what traits in the organisms. Similarly, proteomics analyses the proteins in a tissue to identify the gene expression in that tissue to understand the specific function of proteins encoded by particular genes. Both, along with metabolomics (metabolites) and phenomics (phenotypes), are subcategories of bioinformatics.

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.

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.
How long have genetically engineered organisms been available?
Although genetically engineered organisms in agriculture have been available for only 10 years, their commercial use has expanded rapidly. Recent estimates are that more than 60–70 percent of food products on store shelves may contain at least a small quantity of crops produced with these new techniques.
