[英文釋義] A group of ALGAE,formerly considered FUNGI,whose exact taxonmomic level is unsettled. Many consider Oomycetes (Oomycota) a phylum in the kingdom Stramenopila,or alternatively,as Pseudofungi in the phylum Heterokonta of the kingdom Chromista. They are morphologically similar to fungi but have no close phylogenetic relationship to them. Oomycetes are found in both fresh and salt water as well as in terrestrial environments. (Alexopoulos et al.,Introductory Mycology,4th ed,pp683-4). They produce flagellated,actively motile spores (zoospores) that are pathogenic to many crop plants and FISHES.
