Web20 mrt. 2024 · Some examples of Type II hypersensitivity reaction: 1. Blood transfusion reaction: ABO blood transfusion reaction is an example of type II hypersensitivity … 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. It is … Meer weergeven The first idea of how the hypersensitive response occurs came from Harold Henry Flor's gene-for-gene model. He postulated that for every resistance (R) gene encoded by the plant, there is a corresponding avirulence (Avr) gene Meer weergeven Accidental activation of HR through the NLR proteins could cause vast destruction of the plant tissue, thus, the NLRs are kept in an … Meer weergeven Pathogens have evolved several strategies to suppress plant defense responses. Host processes usually targeted by bacteria include; … Meer weergeven It has been noticed in Arabidopsis that sometimes when two different plant lines are crossed together, the offspring show signs of hybrid necrosis. This is due to the parent plants containing incompatible NLRs, which when expressed together in the same … Meer weergeven HR is triggered by the plant when it recognizes a pathogen. The identification of a pathogen typically occurs when a virulence gene product, secreted by a pathogen, binds to, or indirectly interacts with the product of a plant R gene. R genes are highly Meer weergeven Several enzymes have been shown to be involved in generation of ROS. For example, copper amine oxidase, catalyzes the Meer weergeven Local initiation of HR in response to certain necrotrophic pathogens has been shown to allow the plants to develop systemic immunity against the pathogen.
