Question
Chapter 28, Problem 1DAA
Summary Introduction
To determine: The number of transgenic plants that the researchers used for the test.
Introduction: Transgenic plants are the plants whose genomes are altered or modified by inserting a desired foreign gene using certain genetic engineering techniques. Production of transgenic plant was intended for the expression of desired trait in the plants that does not occur naturally in them. Transgene (foreign gene) can be from unrelated origin. Nowadays, transgenic plants play a significant role in phytoremediation (using plants to clean up the environment). The transgenic plants have the transgene, which makes the plant efficient to remove, utilize, and detoxify the pollutants. It can be used to clean up an important soil and air contaminant.
Expert Solution & Answer
Answer to Problem 1DAA
Correct answer: Six transgenic plants were used for the given test.
Explanation of Solution
The given experiment was started with a plan to produce genetically-engineered plants that are able to remediate (phytoremediation) the soil and air contaminated with organic solvents. A mammalian gene that encodes for the cytochrome P450 (break downs organic solvents) was delivered into poplar plants using the vector Agrobacterium tumefaciens. The transgenic poplar plants were tested for their capability to uptake trichloroethylene (TCE) from air. Refer Figure 28.1, “TCE uptake from air by transgenic poplar plants” in the textbook. The graphical representation showed that six poplar plants were selected for the experiment. Out of these, four were planted transgenic plants, one was bare-rooted transgenic plant, and one was control planted transgenic plant with no gene.

- Genetic engineering of plants provides an opportunity to alter their properties or performance in order to improve upon their utility. Such technology may be used to modify the expression of genes already present in the plants, or to introduce new genes of other species with which the plant cannot be bred conventionally. In fact, humans have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization that significantly modify genomes of organisms. How has this technology created novel genetic information by specific alteration of cloned genes? (provide an example). Why do you think modern genetic engineering, has met with so much opposition? Should some forms of genetic engineering be of greater concern than others? Explain. In your response provide a specific example from literature to describe the implications of this technology (good or bad).arrow_forwardGenetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops.

The mutations in these strains cause a nutritional requirement for an amino acid, such that the strains will not grow in media that lack one specific amino acid. Any mutant that has a nutritional requirement is called an auxotroph, and is incapable of growing in a "minimal medium" containing only a carbon source (e.g., glucose), a simple nitrogen source (e.g., ammonium sulfate), and various salts and minerals. Such strains can be supported on a medium supplemented with only the missing nutrient or on a "rich" medium that contains amino acids, vitamins, nitrogenous bases, etc. (often in the form of an extract from yeast). The wild-type individual that can synthesize the metabolic component is a prototroph, and is capable of growth on minimal medium. The mutant strains in this activity are unable to synthesize tryptophan, lysine, or histidine; one…arrow_forward

- Many plants increase in freezing tolerance upon exposure to low nonfreezing temperatures. Rye, for instance, is killed by freezing at about -5°C, but after a period of exposure to low nonfreezing temperature can survive freezing down to about -30°C. When exposed to low temperatures, plants exhibit an increased expression of certain cold-induced genes that function to stabilize cell membranes against freeze-induced injury. The ability of an individual plant to develop freezing tolerance is best described as an example of: Genetic drift OMutation O Allopatric speciation OAdaptation Acclimation Freeze-induced cellular dehydrationarrow_forwardMany plants increase in freezing tolerance upon exposure to low nonfreezing temperatures.
