Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]
Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Plant pathology involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance ...
The plant microbiome, also known as the phytomicrobiome, plays roles in plant health and productivity and has received significant attention in recent years. [ 1 ] [ 2 ] The microbiome has been defined as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties.
Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella.As a plant pathogen, it can infect a wide range of species, and exists as over 50 different pathovars, [2] all of which are available to researchers from international culture collections such as the NCPPB, ICMP, and others.
In 2022 the World Health Organization (WHO) published a list of fungal pathogens which should be a priority for public health action. [4] Markedly more fungi are known to be pathogenic to plant life than those of the animal kingdom. [5] The study of fungi and other organisms pathogenic to plants is called plant pathology.
immunoevasion, evasion of the host's immune response [1] [2] [3] immunosuppression, inhibition of the host's immune response (this includes leukocidin-mediated cell death) [1] entry into and exit out of cells (if the pathogen is an intracellular one) [4] obtain nutrition from the host [1] Specific pathogens possess a wide array of virulence ...
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.
Agrobacteria have the widest host range of any plant pathogen, [41] so the main factor to take into consideration in the case of crown gall is environment. There are various conditions and factors that make for a conducive environment for A. tumefaciens when infecting its various hosts.
