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.

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).
