Genetics, biochemistry, microbiology and plant physiology are just a few of the many sciences that have historically profited immensely from the knowledge and concepts that have been incorporated into the synthetic field of plant pathology. This is still true today, given that these topics gave rise to the developing field of biotechnology, where techniques from fields like fermentation, cell and tissue technology, and molecular biology are used to solve real-world biological issues. These technologies allow us to create valuable goods, often chemicals or organisms, by using molecules, organelles, cells and tissues as factories. Within a certain discipline, each group of techniques has a long history of development. However, the simultaneous development of numerous biotechnologies that allow for the quick manufacture of compounds with potential for commercial use and of organisms with altered genetic characteristics has drawn attention to biotechnology as a cohesive field in and of itself. Numerous fields of agriculture and forestry are being rapidly improved by new discoveries in molecular biology and genetics. It is crucial for plant pathologists to be aware of these developments since they have a significant impact on our research, instruction, and interactions with the public.
