Chapter 44, Problem 1AC
Summary Introduction

To discuss:

The usefulness of insertion of “nitrogen fixation genes” in crop plants.

Introduction:

The crop plants, such as wheat and corn require an abundance of nitrogen for the preparation of food that will be beneficial to humans for their own consumption. The adequate amount of nitrogen is provided to these plants by supplying fertilizers.

Summary Introduction

To discuss:

The changes that will occur in farming practices once the genes are inserted in crop plants.

Introduction:

The genetically engineered plants are modified plants, in which the genes of interest are inserted. The application of this technique is used in various manners, such as making drought-resistant, salt-resistant, plant, and many more.

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).
What makes the species of Agrobacterium ideal for genetic engineering? Describe its characteristics and its role in producing transgenic plants.
These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the farmer relies on manually removing the weeds, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the weeds but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide. Which of the following is likely to happen if that weed stays in place? The weed will survive long enough to reproduce. In time, the herbicide will no longer be effective on that field. The trait will spread to nearby weeds.
