familyof water moulds. The family includes plant pathogenic fungus-like organisms in the genus Phytophthora; as well as serious plant and animal pathogens in the genus Pythium.
*Live on land (terrestrial), and in water (aquatic), and a combination of the two, (amphibious)
*Live as deadly
parasites, causing some serious plant and animal diseases when terrestrial.
diploid(2N) life stage predominates, with a short haplophaseinitiated during sexual reproductionas well as asexual reproduction( homothallismpredominates in the Family) to fuse gametes.
sporangiamay germinate via a germ tubeor by release of motile zoospores, depending on the species and the environmental conditions.
Pythium" species cause "damping-off" diseases in young plants (seedlings).
