What eukaryotic group does Phytophthora belong to?
Pathogen. Phytophthora (from Greek phytón and phthorá; “plant-destroyer”) is a genus in the Phylum Oomycota, a fungus-like lineage of microscopic eukaryotes in the Kingdom Chromista, sometimes called the Kingdom Stramenopila.
Is Phytophthora a fungus or bacteria?
Abstract. Phytophthora sp. is a genus in the oomycetes, which are similar to filamentous fungi in morphology and habitat, but phylogenetically more closely related to brown algae and diatoms and fall in the kingdom Stramenopila.
Which disease is caused by Phytophthora infestans?
2.2 Late Blight of Potato. Potato late blight, caused by the Oomycete pathogen Phytophthora infestans, is the most notorious plant disease known, largely due to the epidemic that swept across Europe in 1845–46, leading to famine and mass emigration in Ireland (Fraser, 2003).
Why is Phytophthora not a fungus?
2012). These organisms are more like protists, having non-fungal characteristics such as diploid nuclei, cell walls made of cellulosic compounds and glycan, oospores, 2 types of zoospore flagella and tubular cristae in the mitochondria (Rossman & Palm 2006 ).
Is Phytophthora a true fungus?
What causes phytophthora blight. Phytophthora capsici is an oomycete, also known as a water mold. Oomycetes are not true fungi, but are close relatives to certain kinds of algae. Phytophthora has swimming spores known as zoospores that can swim through films of water and saturated soils to locate a new host plant.
Can Phytophthora be cured?
How to Treat and Prevent Phytophthora Disease. Phytophthora root rot is a worldwide problem that can be treated but not completely eradicated. Infected specimens will likely die, unless removed and destroyed beforehand.
What kind of disease does Phytophthora infestans cause?
Phytophthora infestans. Jump to navigation Jump to search. 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.
What kind of organism is Phytophthora de Bary?
Pathogen Phytophthora infestans (Mont.) de Bary is not a true fungus, but rather is regarded as a fungus-like organism. This pathogen is currently classified as an Oomycete, which are members of the kingdom Chromista (Stra- menopiles or Straminopiles). Oomycetes belong to one of two orders, Saprolegniales and Peronosporales.
Where can you find phytophthora blight in the world?
Any location that receives seed tubers from an area where late blight is present is thus also likely to have late blight. Most locations in Asia, South-East Asia and Australia, Africa, the Americas and Europe can have late blight, especially if seed tubers are imported from an area where late blight is persistent.
Is the genus Phytophthora related to the genus Pythium?
However, regardless of the groupings of more general taxa, it is very clear that the genus Phytophthora, the closely related genus Pythium, and the downy mildews (i.e. Bremia, Sclerospora, Peronospora, etc.) are unrelated to ascomycetes and basidiomycetes. Top of page P. infestans is a coenocytic oomycete with rare cross walls.
