The original report of sex in fungi, occurred two centuries ago, based on observations of the fungus Syzygites megalocarpus (Mucoromycotina) (reviewed by Idnurm [1]). This species, was subsequently used in 1904, to represent self-fertile species when the concept of two major mating strategies were developed for the fungi.
Sexual reproduction in Glomeromycotina is unknown, although its occurrence is inferred from genomic studies. However, specialized hyphae produce chlamydospore-like spores asexually; these may be borne at terminal (apical) or lateral positions on the hyphae, or intercalary (formed within the hypha, between sub-apical cells). [ 8 ]
With these methods, many asexually reproducing fungi have now been placed in the tree of life. [ citation needed ] However, because phylogenetic methods require sufficient quantities of biological materials (spores or fresh specimens) that are from pure (i.e., uncontaminated) fungal cultures, for many asexual species their exact relationship ...
Mucor is a microbial genus of approximately 40 species of molds in the family Mucoraceae. [ 1 ] [ 2 ] Species are commonly found in soil , digestive systems , plant surfaces, some cheeses like Tomme de Savoie , rotten vegetable matter and iron oxide residue in the biosorption process.
They are multicellular. Some Rhizopus species are opportunistic human pathogens that often cause fatal disease called mucormycosis. This widespread genus includes at least eight species. [3] [4] Rhizopus 400x magnification. Rhizopus species grow as filamentous, branching hyphae that generally lack cross-walls (i.e., they are coenocytic). They ...
Mucor racemosus is a rapidly growing, weedy mould belonging to the division Mucoromycota. [1] It is one of the earliest fungi to be grown in pure culture and was first isolated in 1886. [ citation needed ] It has a worldwide distribution and colonizes many habitats such as vegetational products, soil and houses.
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and ...
Asexual reproduction is the dominant form of propagation in the Ascomycota, and is responsible for the rapid spread of these fungi into new areas. Asexual reproduction of ascomycetes is very diverse from both structural and functional points of view.
