Phytophthora
A genus of destructive parasitic OOMYCETES in the family Peronosporaceae, order Peronosporales, affecting numerous fruit, vegetable, and other crops. Differentiation of zoospores usually takes place in the sporangium and no vesicle is formed. It was previously considered a fungus.
Spores
The reproductive elements of lower organisms, such as BACTERIA; FUNGI; and cryptogamic plants.
Pythium
A genus of destructive root-parasitic OOMYCETES in the family Pythiaceae, order Peronosporales, commonly found in cultivated soils all over the world. Differentiation of zoospores takes place in a vesicle.
Rhinosporidiosis
Chronic, localized granulomatous infection of mucocutaneous tissues, especially the NOSE, and characterized by HYPERPLASIA and the development of POLYPS. It is found in humans and other animals and is caused by the mesomycetozoean organism RHINOSPORIDIUM SEEBERI.
Ferns
Seedless nonflowering plants of the class Filicinae. They reproduce by spores that appear as dots on the underside of feathery fronds. In earlier classifications the Pteridophyta included the club mosses, horsetails, ferns, and various fossil groups. In more recent classifications, pteridophytes and spermatophytes (seed-bearing plants) are classified in the Subkingdom Tracheobionta (also known as Tracheophyta).
Rhinosporidium
A genus in the order Dermocystidium, class MESOMYCETOZOEA. It causes RHINOSPORIDIOSIS in MAMMALS and BIRDS.
Spores, Bacterial
Heat and stain resistant, metabolically inactive bodies formed within the vegetative cells of bacteria of the genera Bacillus and Clostridium.
Spores, Fungal
Reproductive bodies produced by fungi.
Cucumis
Oomycetes
Eukaryotes in the group STRAMENOPILES, formerly considered FUNGI, whose exact taxonomic 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.
Self-Fertilization
Chytridiomycota
Fungi
A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.
Ulva
Prototheca
Actinomycetales
Bacillus megaterium
A species of bacteria whose spores vary from round to elongate. It is a common soil saprophyte.
Enterobacter cloacae
Cucurbita
Mucorales
An order of zygomycetous fungi, usually saprophytic, causing damage to food in storage, but which may cause respiratory infection or MUCORMYCOSIS in persons suffering from other debilitating diseases.
Bacillaceae
DNA, Ribosomal
Soil Microbiology
The presence of bacteria, viruses, and fungi in the soil. This term is not restricted to pathogenic organisms.
Microscopy, Phase-Contrast
RNA, Ribosomal, 16S
Capsicum
Cell Wall
Sequence Analysis, DNA
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Vitis
Bacillus
A genus of BACILLACEAE that are spore-forming, rod-shaped cells. Most species are saprophytic soil forms with only a few species being pathogenic.
Sigma Factor
Fatty Acids
Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED). (Grant & Hackh's Chemical Dictionary, 5th ed)
Altitude
Microsporum
A mitosporic Oxygenales fungal genus causing various diseases of the skin and hair. The species Microsporum canis produces TINEA CAPITIS and tinea corporis, which usually are acquired from domestic cats and dogs. Teleomorphs includes Arthroderma (Nannizzia). (Alexopoulos et al., Introductory Mycology, 4th edition, p305)
Arthrodermataceae
A family of ascomycetous fungi, order Onygenales, characterized by smooth ascospores. Genera in the family include Arthroderma, Keratinomyces, and Ctenomyces. Several well-known anamorphic forms are parasitic upon the skin.
Trichophyton
Tinea
Fungal infection of keratinized tissues such as hair, skin and nails. The main causative fungi include MICROSPORUM; TRICHOPHYTON; and EPIDERMOPHYTON.
Epidermophyton
A fungal genus which grows in the epidermis and is the cause of TINEA.
Dermatomycoses
Superficial infections of the skin or its appendages by any of various fungi.
