Although widely used, the molecular basis for this glyphosate-resistance has remained obscure. Although research into herbicides began in the early 20th century, the first major breakthrough was the result of research conducted in both the United Kingdom and the United States during the Second World War into the potential use of herbicides in war. If this target site is somewhat altered, the herbicide no longer binds to the site of action and is unable to exert its phytotoxic effect. 10 Are transgenic plants more nutritious? The use of Bt maize is the second most common GM crop, representing 14% of global area of GM crops in nine countries. 1995, Van den Brink . 2: Plant Products of Biotechnology. Weed management systems using crops resistant to other herbicide modes of action such as glufosinate, HPPD inhibitors, and synthetic auxins (2,4-D and dicamba) offer additional tools to manage glyphosate-resistant weeds. Because herbicides tend to affect plants more quickly and severely than animals, the most useful biological sign of herbicides is effects on aquatic plants (Kreutzweiser et al. Similarly, a cow can only mate with another cow. Those volunteer plants have now become weeds that farmers need to address with other control options. In an extreme case, a gene from the bacterium Bacillus thuringiensis (the BT gene) has been transferred into plants.
