Timeline of Modern Protein Biotechnology●1976: The tools of recombinant DNA are first applied to a human
inherited disorder. Molecular hybridization is used for the prenatal diagnosis of alpha thalassemia. Yeast genes arefirst expressed in E. coli.
●1978: Hutchinson, Edgell and Smith demonstrate that its is possible to introduce specific mutations at specific sitesin a DNA molecule and thus produce specifically modifiedrecombinant proteins.
●1978: Human insulin gene cloned into E. coli by Genentech scientists.Genentech licenses the insulin gene technology to Eli Lily.
●1982: Humulin, Genentech’s human insulin produced by Eli Lily,becomes the first FDA approved recombinant DNA drug.
Timeline of Modern Protein Biotechnology, cont.
●1985: Genentech becomes the first biotechnology company to launch its own biopharmaceutical product, ProTropin –growth hormone for children with growth hormone deficiency.

In General, Plant Biotechnology TechniquesFall Into Two Classes
• Identify a gene from another species which controlsa trait of interest
• Or modify an existing gene (create a new allele)
Gene Manipulation
• Introduces that gene into an organism• Technique called transformation• Forms transgenic organisms

In the World in 2003…Global biotech crop acreage grew to more than 167 million acres in 2003 according to the International Service for the Acquisition of Agri-biotech Applications. Since 1996, when the first biotech crops were commercially grown, the global biotech crop area has increased 40-fold to a total of 7 million farmers in 18 countries. A total of 85 percent of growers using biotech crops are small farmers in developing countries, which representsnearly one-third of the global biotech crop area.

Conventional:Wide Hybridization introduces 100,000 potentially negative genes in order to obtain one desirable diseaseresistance gene.
Induced mutagenesis has been used for decades to creategenetic variants.
Genetic Engineering:Introduce one (or a few) foreign “good” genes into thebest accepted cultivar background.
Bt or Disease Resistance genes might enable reduction by80% of insecticide or fungicide chemical applications.

UGA Researchers Use Transgenic Trees To Help Clean Up Toxic Waste SiteCan genetically engineered cottonwood trees clean up a site contaminated with toxic mercury? A team of researchers from the University of Georgia - in the first such field test ever done with trees -is about to find out.The results could make clearer the future of phytoremediation –a technique of using trees, grasses and other plants to remove hazardous materials from the soil. UGA scientists and city officials in Danbury, Conn., planted on July 16 some 60 cottonwoods with aspecial gene at the site of a 19th-century hat factory in that northeastern city. "We hope to see a significant difference in the levels of mercury in the soil within 18 months, perhaps as much as a twofold reduction," said Richard Meagher, professor of genetics at UGA. The field test is a collaboration between UGA, Western Connecticut State University, Applied PhytoGenetics, Inc., of Athens and the City of Danbury.

Mice, men share 99 percent of genesBy Marsha WaltonCNN
(CNN) --When it comes to DNA, it turns out there's not that much difference between mice and men.Mice and humans each have about 30,000 genes, yet only 300 are unique to either organism. Both even have genes for a tail, even though it's not "switched on" in humans."About 99 percent of genes in humans have counterparts in the mouse," said Eric Lander, Director of the Whitehead Institute Center for Genomic Research in Cambridge, Massachusetts. "Eighty percent have identical, one-to-one counterparts."The mouse is the only mammal, after the human, whose genome has been sequenced. The rodent's genetic sequence was published in this week's edition of Nature Magazine
Scientists say mice and humans descended from a common ancestor about the size of a small rat.
