Hongos imperfectos deuteromycetes asexual reproduction

Deuteromycetes (Fungi imperfecti, colloquially: molds)...

The fungi imperfecti or imperfect fungialso known as Deuteromycotaare fungi which do not fit into the commonly established taxonomic classifications of fungi that are based on biological species concepts or morphological characteristics of sexual structures because their sexual form of reproduction has never been observed. Only their asexual form of reproduction is known, meaning that these fungi produce their spores asexually, in the process called sporogenesis.

There are about 25, species that have been classified in the deuteromycota and many are basidiomycota or ascomycota anamorphs. Fungi producing the antibiotic penicillin and those that cause athlete's foot and yeast infections are algal fungi. In Hongos imperfectos deuteromycetes asexual reproduction, there are a number of edible imperfect fungi, including the ones that provide the distinctive characteristics of Roquefort and Camembert cheese.

Other, more informal names besides Deuteromycota "Deuteromycetes" and fungi imperfecti are anamorphic fungior mitosporic fungibut these are terms without taxonomic rank. Examples are Alternaria, Colletotrichum, Trichoderma etc. This is because most fungi are classified based on characteristics Hongos imperfectos deuteromycetes asexual reproduction the fruiting bodies and spores produced during sexual reproduction, and members of the Deutromycota have only been observed to reproduce asexually or produce no spores.

Mycologists are unique among those who study extant organisms in using a dual system of nomenclature.

Dual naming was permitted by Article 59 Hongos imperfectos deuteromycetes asexual reproduction the International Code of Botanical Nomenclature which governs the naming of plants and fungi ; however, this was abolished in the update of the Code.

Under the former system, a name for an asexually reproducing fungus was considered a form taxon. For example, the ubiquitous and industrially important mold, Aspergillus nigerhas no known sexual cycle.

Thus Aspergillus niger is considered a form taxon.

The fungi imperfecti or imperfect...

In contrast, isolates of its close relative, Aspergillus nidulansrevealed it to be the anamorphic stage of a teleomorph the ascocarp or fruiting body of the sexual reproductive stage of a funguswhich was already named Emericella nidulans.

When such a teleomorphic stage is known, that name will take priority over the name of an anamorph which lacks a sexual reproductive stage.

Hence the formerly classified Aspergillus species is now properly called Emericella nidulans. Phylogenetic classification of asexually reproducing fungi now commonly uses molecular systematics. Phylogenetic trees constructed from comparative analyses of DNA sequencessuch as rRNAor multigene phylogenies may be used to infer relationships between asexually reproducing fungi and their sexually reproducing counterparts.

With these methods, many asexually reproducing fungi have "Hongos imperfectos deuteromycetes asexual reproduction" been placed in the tree of life. Under the current system of fungal nomenclature, teleomorph names cannot be applied to fungi that lack sexual structures.

Classifying and naming asexually reproducing fungi is the subject of ongoing debate in the mycological community. These groups are no longer formally accepted because they do not adhere to the principle of monophyly.

In particular, the term 'hyphomycetes' is often used to refer to molds, and the term 'coelomycetes' is used to refer to many asexually reproducing plant pathogens that form discrete fruiting bodies.
