Aspergillus is defined as a group of conidial fungi—that is, fungi in an asexual state. Some of them, however, are known to have a teleomorph (sexual state) in the Ascomycota. With DNA evidence, all members of the genus Aspergillus are members of the phylum Ascomycota. [citation needed]
They have asexual form of reproduction, meaning that these fungi produce their spores asexually, in the process called sporogenesis. There are about 25,000 species that have been classified in the deuteromycota and many are basidiomycota or ascomycota anamorphs .
Aspergillus terreus, also known as Aspergillus terrestris, is a fungus (mold) found worldwide in soil. Although thought to be strictly asexual until recently, A. terreus is now known to be capable of sexual reproduction. [2] This saprotrophic fungus is prevalent in warmer climates such as tropical and subtropical regions. [3]
Fungi are classified primarily based on the structures associated with sexual reproduction, which tend to be evolutionarily conserved.However, many fungi reproduce only asexually, and cannot easily be classified based on sexual characteristics; some produce both asexual and sexual states.
In fungi, both haploid and diploid forms can reproduce – haploid individuals can undergo asexual reproduction while diploid forms can produce gametes that combine to give rise to the next generation. [2] Mating in fungi is a complex process governed by mating types.
Mitotic sporogenesis is a form of asexual reproduction. Examples are the conidial fungi Aspergillus and Penicillium, for which mitospore formation appears to be the primary mode of reproduction. Other fungi, such as ascomycetes, utilize both mitotic and meiotic spores.
Asexual reproduction is the dominant form of propagation in the Ascomycota, and is responsible for the rapid spread of these fungi into new areas. It occurs through vegetative reproductive spores, the conidia .
The reproduction of Aspergillus fischeri could be divided into three way sexual, asexual and parasexual.. Asexual and parasexual are two nonsexual way when fungi reproducing. . The distinction between them are where is the parent hyphae come f
