There are different Types of Genetic Engineering Techniques Which are as follows:-Microbial Vectors: Agrobacterium tumefaciens is considered a naturally occurring soil microbe that is famous for causing crown gall disease on various plant species. This pathogen is unique and unusual because when it attacks a plant cell, it transfers some of its DNA into it. The plant considers the transferred gene as its own. These genes direct the production of several substances, thus causing crown gall.Microprojectile Bombardment: In 1897, Klien and colleagues discovered a technique of delivering naked DNA to plant cells by shooting the DNA with the help of a microscopic pellet. The DNA has to have adhered with the pellet.  This is considered a crude but effective technique to deliver DNA, this type of technique suits species such as corn, rice and other cereals.
