• infection
  • After examination, marine Oomycetes (lower fungi) infection was found to be the reason behind mass mortality of eggs and larvae. (ums.edu.my)
  • Despite not being closely related to the fungi, the oomycetes have developed similar infection strategies. (wikipedia.org)
  • Some species are able to carry a fungus named Batrachochytrium dendrobatidis which in others can cause a deadly infection Chytridiomycosis depending on their microbiome resisting pathogen colonization or inhibiting their growth with antimicrobial skin peptides. (wikipedia.org)
  • For example, corn is planted into a field with corn residue that has the fungus Cercospora zea-maydis, the causal agent of Grey leaf spot of corn, but if the weather is too dry and there is no leaf wetness the spores of the fungus in the residue cannot germinate and initiate infection. (wikipedia.org)
  • Taking the example above, the corn is planted into a ploughed field where there is no corn residue with the fungus Cercospora zea-maydis, the causal agent of Grey leaf spot of corn, present but the weather means long periods of leaf wetness, there is no infection initiated. (wikipedia.org)
  • true fungi
  • These and other differences place fungi in a single group of related organisms, named the Eumycota (true fungi or Eumycetes), which share a common ancestor (form a monophyletic group), an interpretation that is also strongly supported by molecular phylogenetics. (wikipedia.org)
  • zoospores
  • P. megakarya is an oomycete that has a polycyclic disease cycle, producing three asexual spore types: sporangia, zoospores, and chlamydospores. (wikipedia.org)
  • Like all oomycetes, zoospores produced by P. megakarya need free water on plant surfaces in order to encyst, germinate, and penetrate host tissues. (wikipedia.org)
  • Most oomycetes produce self-motile zoospores with two flagella. (wikipedia.org)
  • late blight
  • 2005). An ancestral oomycete locus contains late blight avirulence gene Avr3a , encoding a protein that is recognized in the host cytoplasm. (springer.com)
  • taxa
  • The name "water mold" refers to their earlier classification as fungi and their preference for conditions of high humidity and running surface water, which is characteristic for the basal taxa of the oomycetes. (wikipedia.org)
  • Oomycota
  • Oomycota" means "egg fungi", referring to the large round oogonia, structures containing the female gametes, that are characteristic of the oomycetes. (wikipedia.org)
  • Oomycota and fungi have different metabolic pathways for synthesizing lysine and have a number of enzymes that differ. (wikipedia.org)
  • The ultrastructure is also different, with oomycota having tubular mitochondrial cristae and fungi having flattened cristae. (wikipedia.org)
  • algae
  • Oomycetes, or water moulds, are fungal-like organisms phylogenetically related to algae. (royalsocietypublishing.org)
  • Oomycetes, or water moulds, are fungal-like eukaryotes classified as stramenopiles, and are phylogenetically grouped with diatoms and brown algae [ 1 - 4 ]. (royalsocietypublishing.org)
  • The lower-case for "algae, fungi, and plants" indicates that these terms are not formal names of clades, but indicate groups of organisms that were historically known by these names and traditionally studied by phycologists, mycologists, and botanists. (wikipedia.org)
  • Some but not all subsequent meetings of the International Botanical Congress have produced revised versions of these Rules, later called the International Code of Botanical Nomenclature, and then International Code of Nomenclature for algae, fungi, and plants. (wikipedia.org)
  • soil
  • Many soil inhabiting fungi are capable of living saprotrophically, carrying out the part of their life cycle in the soil. (wikipedia.org)
  • Abundant worldwide, most fungi are inconspicuous because of the small size of their structures, and their cryptic lifestyles in soil or on dead matter. (wikipedia.org)
  • haustoria
  • Lesions are the result of oomycetes leaching nutrients out of the leaves via haustoria to create white powdery rings of sporangia. (wikipedia.org)
  • mycology
  • The discipline of biology devoted to the study of fungi is known as mycology (from the Greek μύκης mykes, mushroom). (wikipedia.org)
  • The use of the word mycology, which is derived from the Greek mykes (μύκης "mushroom") and logos (λόγος "discourse"), to denote the scientific study of fungi is thought to have originated in 1836 with English naturalist Miles Joseph Berkeley's publication The English Flora of Sir James Edward Smith, Vol. 5. (wikipedia.org)
  • hypha
  • The oomycetes rarely have septa (see hypha), and if they do, they are scarce, appearing at the bases of sporangia, and sometimes in older parts of the filaments. (wikipedia.org)
  • cell
  • Present study explains the structural dynamism of cell wall which is believed to have functional relevance and is dependent on the behavior of the infecting fungi. (springer.com)
  • Moreover, cell wall is also known to elicit immune signals that brings about transcriptional reprogramming and helps in mounting defense against attacking fungi. (springer.com)
  • The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. (wikipedia.org)
  • microscopic
  • Ever since the pioneering 18th and 19th century taxonomical works of Carl Linnaeus, Christian Hendrik Persoon, and Elias Magnus Fries, fungi have been classified according to their morphology (e.g., characteristics such as spore color or microscopic features) or physiology. (wikipedia.org)
