"Since the early 1990’s genetically engineered plants have been commercially available. So called “first generation” transgenic plants have been engineered for characteristics that enhance the agricultural yield and marketing. Such characteristics include resistance to pests, herbicides and extreme climates, as well as improved product shelf life. For example, since their first commercial cultivation in 1996, plants have been genetically modified for tolerance to the herbicides glufosinate and glyphosate. A “second generation” of transgenic plants, now in research and development, is aimed at enhancing consumer satisfaction by enhancing taste, texture, or appearance of produce. To date, no second generation transgenic plants are on the market."
