Os Beneficícios das Culturas Biotecnológicas para a Saúde e o Meio Ambiente (208 KB)
Kimbal Nill and Joseph R. Zak
The first category of biotech crops is the input traits. It contains for instance a new biotechnology-derived herbicide-tolerant soy which holds the potential to end herbicide pollution. Activist groups in Western Europe have opposed the technology, arguing that it might somehow be riskier than so-called "traditional plant breeding". Biotechnology firms test all new introduced proteins extensively for potential allergenicity and toxicity. The second category (i.e., output traits) includes a coming myriad of improved soybean, maize and other grain varieties, having been created via both traditional breeding and via biotechnology. Some examples are the low-phytate soybean, high-phytase soybean, low-stachyose soybean, high-oleic soybean, low-linolenic soybean, high lysine, high-methionine, high-threonine, etc soybean and oligofructan- and CLA-containing soybean. |
