What is a plant pathogen?
Plant pathogen is an organism causing a disease that attacks plants. Plants' pathogens are interesting for many reasons, from concerns about fragile ecosystems to the desire to protect food supply. There are many types of pathogens that can target plants, including viruses, bacteria, protozoans, parasites, worms and archaea. People who study plants are known as phytopatologists or plant pathologists. Some colonize tissue in the plant, others settle on the surface of the plant and others can go to specific areas such as roots, stems and leaves. Pathogens usually cause problems such as tissue death, browning, fetal reduction, flower settings, etc. In extreme cases, they can kill the host plant.
As the pathogens that attack people, plant pathogens are very diverse. Plant pathogen could develop to attack specific gender or plant species, or infect most of the plants. Some plant pathogens use specific bioloGical processes that may occur in host species, while others are content with the use of plants as a home because they have valuable resources such as nutrients.
In agriculture, plants pathogens cause serious damage every year. Once the plant is attacked by plant pathogen, its products usually cannot be sold. The investment in the race is unnecessary by the pathogen and usually participates in the eradication of pathogens from the field and solving another closer of contamination. In some cases, the fields are so ill that it must be allowed to lie for several years before trying to re -grow crops.
plants can also be concerned when it is accidentally imported or intentionally introduced into a vulnerable ecosystem. Some island -conscious dealing with it because they have a unique flora that could be decimated by established pathogen of the mainland. Pathogens may also be a problem when spreading between OKResy; For example, a pathogen that attacks grapes and is limited to Europe can pose a main threat if it reaches a winery in Australia, which may not be ready to control the pathogen.
ecologists are interested in studying pathogens that can infect plants and look at their effects on different types and ecosystems. When plants experience DieOffs and other problems, the cause of plants is often caused and a pathologist can be called to find out which pathogen is responsible and to create a plan for its management.
