Transcript of Explain how a gene for pest resistance that has been inserted into plants is indirectly beneficial to the environment.

Gene Inserted Into Plants This technique is referred to as plant cell culture. One of the applications of biotechnology in agriculture is the production of pest resistant plants. BIOTECHNOLOGICAL APPLICATIONS IN AGRICULTURE Bacillus thuringiensis (or Bt) is a soil-dwelling bacterium, commonly used as a biological pesticide; alternatively, the Cry toxin may be extracted and used as a pesticide. Scientists have been able to clone specific genes from one species and insert them into plants to introduce new traits that may benefit the plant species. This procedure is known as transgenics and gives rise to genetically modified crops. A nematode Meloidegyne incognitia infects the roots of tobacco plants and causes a great reduction in yield Using Agrobacterium vectors, nematode-specific genes were introduced into the host plant Explain how a gene for pest resistance that has been inserted into plants is indirectly beneficial to the environment. Plant diseases can drastically abate the crop yields as the degree of disease outbreak is getting severe around the world. Pest Resistant Crops Insect attack is a serious agricultural problem leading to yield losses and reduced product quality. Insects can cause damage both in the field and during storage in silos. Each year, insects destroy about 25 percent of food crops worldwide.
