Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1]
1902; First chair of plant pathology established, in Copenhagen [1] 1904; Mendelian inheritance of cereal rust resistance demonstrated [1] 1907; First academic department of plant pathology established at Cornell University [1] 1908; American Phytopathological Society founded [1] 1910; Panama disease reaches Western Hemisphere [5]
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
Relative to a susceptible plant, disease resistance is the reduction of pathogen growth on or in the plant (and hence a reduction of disease), while the term disease tolerance describes plants that exhibit little disease damage despite substantial pathogen levels.
The Annual Review of Phytopathology is a peer-reviewed academic journal that publishes review articles about phytopathology, the study of diseases that affect plants.It was first published in 1963 as the result of a collaboration between the American Phytopathological Society and the nonprofit publisher Annual Reviews.
Capsidiol is a phytoalexin produced by certain plants in response to pathogenic attack.. Phytoalexins are antimicrobial substances, some of which are antioxidative as well. They are defined not by their having any particular chemical structure or character, but by the fact that they are defensively synthesized de novo by plants that produce the compounds rapidly at sites of pathogen infection.
When the smut invades the host plant it causes hypertrophy – the host's cells increase in size and number. (The fungus also destroys the flowering structures of the plant, so it does not make seed, but the plants can still be propagated asexually by rhizome.) In an environment such as a rice paddy, new sprouts of wild rice are easily infected ...
This is a glossary of some of the terms used in phytopathology.. Phytopathology is the study of plant diseases. It is a multi-disciplinary science since prerequisites for disease development are the presence of a susceptible host species, a pathogen and the appropriate environmental conditions.
