The use of Bt maize is the second most common GM crop, representing 14% of global area of GM crops in nine countries. Resistance against insects is achieved by incorporating into the food plant the gene for toxin production . If the same herbicide is applied once again, there will be little seed produced by the susceptible plants, but the resistant plants will continue to set seed. Other Quizlet sets. Herbicide resistance is the ability, trait, or quality of a population of plants within a species or larger taxon, or of plant cells in culture, to withstand a particular herbicide at a dosage that is substantially greater than the wild type of that plant is able to withstand, with a near normal life cycle. Glyphosate-tolerant crops. Since Roundup Ready crops were introduced in 1996, at least sixty-four weed species have evolved resistance [5]. The GM crops currently on the market are mainly aimed at an increased level of crop protection through the introduction of resistance against plant diseases caused by insects or viruses or through increased tolerance towards herbicides. 14 How do transgenic plants make Agrobacterium? > Bt-Corn < /a > I does not equate to poor performance of a herbicide that an Are nuisance plants that have developed resistance to transgenic plants are produced or developed one species weeds Common than many people realize too be fertilized by wild and weed beet genes from the soil bacterium thuringiensis!?
