Researchers from the University of Maryland in Baltimore (Maryland), the Boyce Thompson Institute for Plant Research in Ithaca (New York), and Tulane University in New Orleans (Louisiana) have performed the hrst human trial of edible vaccine. Potatoes were genetically engineered to produce a diarrhea-causing toxin secreted by the bacterium Escherichia coli. 

The question also arises as to whether there is a potential allergenicity risk for people who happen to inhale or topically receive pollen from genetically engineered plants (indirect contact) that may then cause an allergic reaction or immunity (Davies, 2005). Since the proteins produced in plants tend to be highly specific, the risk to human health is negligible (Goldstein and Thomas, 2004). 

Bt crop A crop plant genetically engineered to produce insecticidal toxins derived from the bacterium Bacillus thuringiensis. Current commercial Bt crops include Bt cotton, Bt corn, and Bt soybeans. 

Here, we have summarized the stress response molecular mechanisms and their biotechnological applications. Based on the various stress response mechanisms and the identification of the corresponding stress-induced genes, genetically engineered plants have been produced and...

The second event, that of Prodigene s PMP corn, is one immediately relevant for PMP production. In September and October of 2002, in Iowa and Nebraska respectively, APHIS found volunteer corn plants genetically engineered to produce a pharmaceutical to prevent traveler s diarrhea growing in soybean fields in violation of permit conditions. Specifically, Prodigene did not abide by the conditions of their field release permit to eradicate all traces of the experimental crop from the fields, as small quantities of this corn ended up in soybean that was to be processed and sold for human consumption. 

It is only a matter of time before new oils will be produced from genetically engineered plants. This, however, will require in-depth studies into the mechanisms of FA and oil synthesis, and especially into the interactions between particular stages of their synthesis and the controlling mechanisms. 

As most secondary metabolites are only made in low amounts and are often found in wild-type plants not optimized for cultivation, supply of the desired molecule is often limited or at least very costly. To overcome this bottleneck, different ways have been developed to produce important metabolites or precursors in cell cultures, tissue cultures, or in higher amount in whole plants [44], PacUtaxel (an anticancer agent) is one of these substances with high commercial value where independently estabUshed suspension cultures of genetically engineered plant cells have been patented as production process [52, 53).
