Innovations in molecular biology and plant genetic engineering
have made it possible to introduce genes from virtually any source into important
crop plants. One example of this is the BT-toxin gene from the bacterium, Bacillus
thuringiensis. This gene encodes a protein that is toxic to certain types of
insects (e.g., lepidopteran larvae). One serious insect pest of corn (Zea mays)
is the larva of the European Corn Borer moth. During the summer of 1997 transgenic
corn containing the BT-toxin gene was commercially grown in the state of Iowa
for the first time. Since that time, increasing amounts of Bt-toxin containing
corn have been grown each summer in Iowa.
Part 1
Find, and post on the Assignment 4 discussion forum, one web-site that addresses the topic of BT-toxin containing corn. You can post the site as a link using the following HTML:
<a href="Your URL">Your Link Name</a>
Repeat sites will NOT be accepted for full credit - so get your site posted
early. (2 points)
Part 2
Write a paragraph describing what you believe to be the costs
and benefits of employing BT-toxin containing plants in the production of corn
grain. Conclude with a recommendation regarding whether you believe that this
technology should, or should not be, widely adopted. (5 points)
Part 3
Reply to one of your colleague's recommendations, stating whether
you agree or disagree with their recommendation and WHY. (3 points)
