It has been seeking regulatory approval in the United States since 1995. And while neither Canada nor the U.S. has approved the fish for human consumption, Environment Canada's decision to…

Researchers have developed genetically modified citrus trees that show enhanced resistance to greening, and have the potential to resist canker and black spot, as well. However, the commercial availability of those trees is still several years away. They used a gene isolated from the Arabidopsis plant, a member of the mustard family, to create the new trees. They used sweet orange cultivars Hamlin and Valencia and created plants that defend themselves against pathogens utilizing a process…
