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.
Antagonism (in phytopathology) occurs when one organism inhibits or slows down the growth of a plant disease-causing organism, such as harmful bacteria or fungi. [1] Most plants can host a variety of pathogens and are often infected by multiple species simultaneously. [2]
So-called "core" effectors are defined operationally by their wide distribution across the population of a particular pathogen and their substantial contribution to pathogen virulence. Genomics can be used to identify core effectors, which can then be used to discover new R gene alleles, which can be used in plant breeding for disease resistance.
Chloroflexus aurantiacus has been of interest in the search for origins of the so-called type II photosynthetic reaction center. One idea is that bacteria with respiratory electron transport evolved photosynthesis by coupling a light-harvesting energy capture system to the pre-existing respiratory electron transport chain.
[3] Many forms of stimulus have been found to induce the plant to the virus, bacteria and fungi and other disease resistance including mechanical factors (dry ice damage, electromagnetic, ultraviolet, and low temperature and high temperature treatment, etc.), chemical factors (heavy metal salts, water, salicylic acid), and biological factors ...
Burkholderia gladioli is a species of aerobic gram-negative rod-shaped bacteria [1] that causes disease in both humans and plants. It can also live in symbiosis with plants and fungi [2] and is found in soil, water, the rhizosphere, and in the microbiome of many animals. It was formerly known as Pseudomonas marginata.
In this mutualistic relationship, the bacteria grow on or within the root hair and penetrate into the plant tissues [3] Although the exact means of interaction between the Rhizobia and plant varies with genus and species, all forms of this interaction are made up of the infection of bacteria, bacteria colonization, control of O 2, and exchange ...
Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses. Abiotic factors that can damage plants include ...
