Microorganisms can be used in all environments of human activity. They are easy to use in the laboratory. For example, in nature there is a bacterium that releases a toxin that kills many harmful insects. The gene responsible for the synthesis of this toxin was isolated from the bacterial genome and inserted into the genome of cultivated plants. To date, pest-resistant varieties of corn, rice, potatoes and other agricultural plants have already been created. Growing such transgenic plants that do not require the use of pesticides has huge advantages, because, firstly, pesticides kill not only harmful but also beneficial insects, and secondly, many pesticides accumulate in the environment and have a mutagenic effect on living organisms
