WebJan 1, 2024 · Host plant resistance is one of the dominant factors in regulating the population of herbivorous insects, in addition to the natural enemies. The resistant plants are able to decrease the development of herbivores and/or significantly reduce the damage caused by them. WebJul 13, 2024 · Host and nonhost mechanisms of rust resistance. Race-specific and non–race-specific resistances can be phenotypically quite different (A versus B). (A) Strong resistance is conferred by NLR proteins such as stem rust resistance 45 (Sr45) and is associated with a hypersensitive response.
Among the thousands of species of plant pathogenic microorganisms, only a small minority have the capacity to infect a broad range of plant species. Most pathogens instead exhibit a high degree of host-specificity. Non-host plant species are often said to express non-host resistance. The term host resistance is used when a pathogen species can be pathogenic on the host species but certain strains of that plant species resist certain strains of the pathogen species. The cause…
WebPhytophthora cinnamomi, also known as cinnamon fungus, is a soil-borne water mould that produces an infection which causes a condition in plants variously called "dieback", "root rot", or (in certain Castanea species), "ink disease".
