Phytophthora infestans

Phytophthora infestans. Phytophthora infestans caused the complete loss of the Irish potato crop between 1845 and 1852 and was responsible for the Irish potato famine that led to the death of ∼1 million people and the emigration of ∼1.5 million people from Ireland. From: Encyclopedia of Agriculture and Food Systems, 2014. Related terms: Cultiva Phytophthora infestans causes serious losses of potato crops worldwide and is probably the most important pathogen of potato and tomato today. The disease, late blight, is famous for the destruction of the potato crops in Ireland in the 1840s and the resulting famine and death of over a million people Turkensteen LJ, 1978.

Phytophthora infestans is heterothallic(6). Under cool wet conditions, Phytophthora oospores or chlamydospores which will germinate to form hyphae or directly produce sporangia. The sporangia are able to detach and travel in the air(6). The sporangia then release free swimming zoospores that have two flagella, one tinsel and one flagellate Phytophthora infestans. Phytophthora infestans causes a disease called late blight of potato, which was the cause of the Irish potato famine in the 1840s, in which more than a million Irish people perished and another million emigrated Phytophthora infestans causes potato and tomato late blight, economically the most important disease of these plant species. The Oomycete pathogen is frequently sampled, isolated to pure cultures. The oomycete, Phytophthora infestans, is one of the most important plant pathogens worldwide. Much of the pathogenic success of P. infestans, the potato late blight agent, relies on its ability to generate large amounts of sporangia from mycelia, which release zoospores that encyst and form infection structures Phytophthora infestans è un oomicete o muffa acquosa, un microrganismo che causa la gravemalattia della patata e del pomodoro nota come peronospora o peronospora.

Phytophthora infestans is an oomycete or water mold that causes the serious potato disease known as late blight or potato blight.(Early blight, caused by Alternaria solani, is also often called potato blight).Late blight was a major culprit in the 1840s European, the 1845 Irish and 1846 Highland potato famines.The organism can also infect tomatoes and some other members of the Solanaceae Phytophthora infestans 88069tdT10 was grown in Petri dishes (90 mm diameter) of rye agar medium supplemented with geneticin antibiotic at 19°C. The P. infestans strain, Ljx18 (race 3.4.7.10.11) and HB09‐14‐2 (race 1.2.3.4.5.6.7.9.10.11, collected from Hubei Province, China), were cultured and propagated on rye agar at 19°C. Spores were. Phytophthora infestans produces both cytoplasmic and apoplastic effectors. Apoplastic effectors act outside the plant cell and include inhibitors of host hydrolases and proteases ( Tian et al. , 2007 ; Damasceno et al. , 2008 ), whereas cytoplasmic effectors function within host cells and have a diverse range of targets and activities ( Whisson. Potato is the world's fourth largest food crop yet it continues to endure late blight, a devastating disease caused by the Irish famine pathogen Phytophthora infestans. Breeding broad-spectrum disease resistance (R) genes into potato (Solanum tuberosum) is the best strategy for genetically managing

Phytophthora infestans is the causal agent of potato late blight. Genotypes of Japanese populations of P. infestans have been classified as US-1, JP-1, JP-2, JP-3, and JP-4 based on analyses of DNA polymorphisms. These populations may have been introduced to Japan by the migration of P. infestans from other countries and by domestic changes produced through sexual and asexual propagation Phytophthora infestans, has become more difficult to control, following the introduction of new strains of the pathogen during the 1970s.

  4. Phytophthora infestans has been a named pathogen for well over 150 years and yet it continues to emerge, with thousands of articles published each year on it and the late blight disease that it causes. This review explores five attributes of this oomycete pathogen that maintain this constant attention

In most locations worldwide, populations of Phytophthora infestans are asexual and are often dominated by one or a few clonal lineages. The dominance in a population by any of these clonal lineages can be ephemeral. Studies in the USA and in the United Kingdom illustrate that dominance by any one clonal lineage may range from a year to two to fifteen years. In the eastern USA, lineage US22. Phytophthora infestans. Phytophthora infestans is an oomycete or water mold, a microorganism that causes the serious potato and tomato disease known as late blight or potato blight. ( Early blight, caused by Alternaria solani , is also often called potato blight.

Phytophthora infestans, the causal agent of potato late blight, triggered the devastating Great Irish Famine that lasted from 1845 to 1852. Today, it is still the greatest threat to the potato yield. Ethylicin is a broad-spectrum biomimetic-fungicide.

Phytophthora infestans Culprit of the Irish Potato Famine Many may be familiar with the devastating story of the Irish Potato Famine that occurred in the mid 1800 s, but relatively few may realize that the organism that caused the tragedy, Phytophthora infestans, has proved to be a problem in recent years The oomycete Phytophthora infestans is a plant pathogen. It is the causal agent of potato blight and was responsible for the Irish Potato Famine in the 1840s. Phytophthora infestans was originally thought to be a lower fungus, but recent research has shown that it is better classified, along with diatoms and brown and golden algae, in the stramenopile lineage Phytophthora infestans (pronounced fy-TOF-thor-uh in-FEST-ans) is a rather common pathogen of potatoes wherever they are grown, but it is usually not a problem unless the weather is unusually cool and wet. The water is necessary for the spores to swim to infect the leaves of the potatoes; the tubers and roots of the potato are more resistant to the pathogen

Phytophthora infestans research The James Hutton Institute is a world leader in many areas of late blight research. The James Hutton Institute and the University of Dundee has established itself as a leader in the study of late blight by integrating research, facilities, resources and skills into a coherent team Phytophthora infestans effector AVR3a is essential for virulence and manipulates plant immunity by stabilizing host E3 ligase CMPG1. Proc. Natl. Acad. Sci. USA 107: 9909 - 9914 Phytophthora infestans is the causal agent of the late potato blight disease and also infects tomatoes and other members of the Solanaceae. This oomycete caused several major crop losses including the Great Famine in Ireland. This pathogen can affect a large area reproducing asexually through spores Phytophthora infestans is the causative agent that can destroy all potato parts, including leaves, stems and tubers , and is the main threat to potato production and responsible for 16% of yield losses globally (Haverkort et al., 2016)
