Pythium spp. tend to be very generalistic and unspecific in their large range of hosts, while Phytophthora spp. are generally more host-specific. For this reason, Pythium spp. are more devastating in the root rot they cause in crops, because crop rotation alone often does not eradicate the pathogen as Pythium spp. are … Visa mer Pythium is a genus of parasitic oomycetes. They were formerly classified as fungi. Most species are plant parasites, but Pythium insidiosum is an important pathogen of animals, causing pythiosis.

WebbPythium is homothallic i.e., male and female sex organs develop in close proximity of each other either on the same or different hypha embedded in the host tissue. However, some species are eterothallic e.g., P. heterothalicum, P. sylvaticum. Male and female sex organs are called anthcridia and oogonia, respectively. Antheridium: littlecote house hotel room plan
