Mucoromycotina

Mucoromycota is a division within the kingdom fungi. [1] It includes a diverse group of various molds, including the common bread molds Mucor and Rhizopus . [2] It is a sister phylum to Dikarya. [3] [4]

Contents

Informally known as zygomycetes I, Mucoromycota includes Mucoromycotina, Mortierellomycotina, and Glomeromycotina, and consists of mainly mycorrhizal fungi, root endophytes, and plant decomposers. [3] Mucoromycotina and Glomeromycotina can form mycorrhiza-like relationships with nonvascular plants. [5] Mucoromycota contain multiple mycorrhizal lineages, [6] root endophytes, [7] and decomposers of plant-based carbon sources. [8] Mucoromycotina species known as mycoparasites, or putative parasites of arthropods are like saprobes. [9] When Mucoromycota infect animals, they are seen as opportunistic pathogens. [3] Mucoromycotina are fast-growing fungi and early colonizers of carbon-rich substrates. [10] Mortierellomycotina are common soil fungi that occur as root endophytes of woody plants and are isolated as saprobes. [11] Glomeromycotina live in soil, forming a network of hyphae, but depend on organic carbon from host plants. In exchange, the arbuscular mycorrhizal fungi provide nutrients to the plant. [12]

Reproduction

Known reproduction states of Mucoromycota are zygospore production and asexual reproduction. Zygospores can have decorations on their surface and range up to several millimeters in diameter. [13] Asexual reproduction typically involves the production of sporangiospores or chlamydospores. [3] Multicellular sporcaps are present within Mucoromycotina, [14] Mortierellomycotina [15] and as aggregations of spore-producing in species of Glomeromycotina. [6] Shown in Mucorales, sexual reproduction is under the control of mating type genes, sexP and sexM, which regulate the production of pheromones required for the maturation of hyphae into gametangia. [16] [13] The sexP gene is expressed during vegetative growth and matting, while the sexM gene is expressed during mating. [17] 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] Species of Glomeromycotina produce coenocytic hyphae that can have bacterial endosymbionts. [18] Mortierellomycotina reproduce asexually by sporangia that either lack or have a reduced columella, which support the sporangium. [3] Species of Mortierellomycotina only form microscopic colonies, but some make multicellular sporocarps. [15] Mucoromycotina sexual reproduction is by prototypical zygospore formation and asexual reproduction and involves the large production of sporangia. [3]

Morphology

Mucoromycotina contain discoidal hemispherical spindle pole bodies. Although spindle pole bodies function as microtubule organizing centers, they lack remnants of the centrioles' characteristic 9+2 microtubule arrangement. Species of Mucoromycotina and Mortierellomycotina produce large-diameter, coenocytic hyphae. Glomeromycotina also form coenocytic hyphae with highly branched, narrow hyphal arbuscules in host cells. When septations occur in Mucoromycota they are formed at the base of reproductive structures. [3]

Production of lipids, polyphosphates, and carotenoids

Mucoromycota's metabolism can utilize many substrates that are from various nitrogen and phosphorus resources to produce lipids, chitin, polyphosphates, and carotenoids. They have been found to co-produce metabolites in a single fermentation process like polyphosphates and lipids. [19] The overproduction of chitin from Mucoromycota fungi can be accomplished by limiting inorganic phosphorus. [20] Mucoromycota are capable of accumulating high amounts of lipids in their cell biomass, which allows the fungi to produce polyunsaturated fatty acids and carotenoids. They have been found to induce antimicrobial activity from fungal crude total lipids. [21] [22] The high production of lipids from Mucoromycota have the potential for use in biodiesel production. [23] [24]

<span class="mw-page-title-main">Zygomycota</span> Division or phylum of the kingdom Fungi

Zygomycota, or zygote fungi, is a former division or phylum of the kingdom Fungi. The members are now part of two phyla: the Mucoromycota and Zoopagomycota. Approximately 1060 species are known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material. Some are parasites of plants, insects, and small animals, while others form symbiotic relationships with plants. Zygomycete hyphae may be coenocytic, forming septa only where gametes are formed or to wall off dead hyphae. Zygomycota is no longer recognised as it was not believed to be truly monophyletic.

An arbuscular mycorrhiza (AM) is a type of mycorrhiza in which the symbiont fungus penetrates the cortical cells of the roots of a vascular plant forming arbuscules. Arbuscular mycorrhiza is a type of endomycorrhiza along with ericoid mycorrhiza and orchid mycorrhiza .They are characterized by the formation of unique tree-like structures, the arbuscules. In addition, globular storage structures called vesicles are often encountered.

<span class="mw-page-title-main">Glomeromycota</span> Phylum of fungi

Glomeromycota are one of eight currently recognized divisions within the kingdom Fungi, with approximately 230 described species. Members of the Glomeromycota form arbuscular mycorrhizas (AMs) with the thalli of bryophytes and the roots of vascular land plants. Not all species have been shown to form AMs, and one, Geosiphon pyriformis, is known not to do so. Instead, it forms an endocytobiotic association with Nostoc cyanobacteria. The majority of evidence shows that the Glomeromycota are dependent on land plants for carbon and energy, but there is recent circumstantial evidence that some species may be able to lead an independent existence. The arbuscular mycorrhizal species are terrestrial and widely distributed in soils worldwide where they form symbioses with the roots of the majority of plant species (>80%). They can also be found in wetlands, including salt-marshes, and associated with epiphytic plants.

<span class="mw-page-title-main">Mucorales</span> Order of fungi

The Mucorales is the largest and best-studied order of zygomycete fungi. Members of this order are sometimes called pin molds. The term mucormycosis is now preferred for infections caused by molds belonging to the order Mucorales.

<i>Glomus</i> (fungus) Genus of arbuscular mycorrhizal fungi

Glomus is a genus of arbuscular mycorrhizal (AM) fungi, and all species form symbiotic relationships (mycorrhizae) with plant roots. Glomus is the largest genus of AM fungi, with ca. 85 species described, but is currently defined as non-monophyletic.

<i>Mucor</i> Genus of fungi

Mucor is a microbial genus of approximately 40 species of molds in the family Mucoraceae. 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.

<i>Mortierella</i> Genus of fungi

Mortierella species are soil fungi belonging to the order Mortierellales within the subphylum Mortierellomycotina. The widespread genus contains about 85 species.

<i>Mucor mucedo</i> Species of fungus

Mucor mucedo, commonly known as the common pinmould, is a fungal plant pathogen and member of the phylum Mucoromycota and the genus Mucor. Commonly found on soil, dung, water, plants and moist foods, Mucor mucedo is a saprotrophic fungus found world-wide with 85 known strains. It is often mistaken for Rhizopus rots on fruits due to similar mould growth shape and colour. Contrastingly, however, Mucor mucedo is found to grow on a wide range of stored grains and plants, including cucumber and tomato. Discovered in Italy in 1729 by P.A. Micheli and later noted by Carl Linnaeus in 1753 in the Species Plantarum, Mucor mucedo was originally classified as Mucor vulgaris by Micheli but later classified synonymous under name Mucor mucedo. The species was redescribed as Ascophora mucedo by H.J. Tode in 1790 but this type resided in a stoloniferous habitat and was later made the type of new genus Rhizopus.

<i>Mucor racemosus</i> Species of fungus

Mucor racemosus is a rapidly growing, weedy mould belonging to the division Mucoromycota. It is one of the earliest fungi to be grown in pure culture and was first isolated in 1886. It has a worldwide distribution and colonizes many habitats such as vegetational products, soil and houses. The fungus is mostly known for its ability to exhibit both filamentous and yeast-like morphologies, often referred to as dimorphism. Stark differences are seen in both forms and conditions of the environment heavily affect the phases of the M. racemosus. Like many fungi, it also reproduces both sexually and asexually. The dimorphic capacity of this species has been proposed as an important factor in its pathogenicity and has enhanced the industrial importance. This species is considered an opportunistic pathogen, generally limited to immunocompromised individuals. It also been associated with allergy and inflammations of facial sinuses. Its association with allergy has made it a common fungus used in allergen medical testing. Industrial use of the fungus is in the production of enzymes and the manufacture of certain dairy foods.

These gametes are similar in morphology (isogamous) or dissimilar.

<span class="mw-page-title-main">Mucoromycotina</span> Subphylum of fungi

Mucoromycotina is a subphylum of uncertain placement in Fungi. It was considered part of the phylum Zygomycota, but recent phylogenetic studies have shown that it was polyphyletic and thus split into several groups, it is now thought to be a paraphyletic grouping. Mucoromycotina is currently composed of 3 orders, 61 genera, and 325 species. Some common characteristics seen throughout the species include: development of coenocytic mycelium, saprotrophic lifestyles, and filamentous.

<span class="mw-page-title-main">Plant use of endophytic fungi in defense</span>

Plant use of endophytic fungi in defense occurs when endophytic fungi, which live symbiotically with the majority of plants by entering their cells, are utilized as an indirect defense against herbivores. In exchange for carbohydrate energy resources, the fungus provides benefits to the plant which can include increased water or nutrient uptake and protection from phytophagous insects, birds or mammals. Once associated, the fungi alter nutrient content of the plant and enhance or begin production of secondary metabolites. The change in chemical composition acts to deter herbivory by insects, grazing by ungulates and/or oviposition by adult insects. Endophyte-mediated defense can also be effective against pathogens and non-herbivory damage.

<i>Rhizophagus irregularis</i> Species of arbuscular mycorrhizal fungus used as a soil inoculant in agriculture and horticulture

Rhizophagus irregularis is an arbuscular mycorrhizal fungus used as a soil inoculant in agriculture and horticulture. Rhizophagus irregularis is also commonly used in scientific studies of the effects of arbuscular mycorrhizal fungi on plant and soil improvement. Until 2001, the species was known and widely marketed as Glomus intraradices, but molecular analysis of ribosomal DNA led to the reclassification of all arbuscular fungi from Zygomycota phylum to the Glomeromycota phylum.

Dark septate endophytes (DSE) are a group of endophytic fungi characterized by their morphology of melanized, septate, hyphae. This group is likely paraphyletic, and contain conidial as well as sterile fungi that colonize roots intracellularly or intercellularly. Very little is known about the number of fungal taxa within this group, but all are in the Ascomycota. They are found in over 600 plant species and across 114 families of angiosperms and gymnosperms and co-occur with other types of mycorrhizal fungi. They have a wide global distribution and can be more abundant in stressed environments. Much of their taxonomy, physiology, and ecology are unknown.

Umbelopsis ramanniana is a common and abundant soil fungus. Although the ecological role of this fungus in natural ecosystems is not yet known, it is a cosmopolitan saprotroph in soil, forest leaf litter, in animal dung, and on the spore-producing bodies of ascomycete fungi. Umbelopsis ramanniana has also been found growing as an endophyte within xylem tissue of both healthy and declining conifers, but its exact effect on the plant hosts is unknown. Umbelopsis ramanniana is a representative of a unique group of zygomycete fungi that is distinct from the Mucoromycotina and Mortierellomycotina and instead forms an early diverging lineage within the Mucoralean fungi. Umbelopsis ramanniana is important from a biochemistry and biotechnology perspective because it is highly tolerant to fungicides of benomyl group, and it is oleaginous. Expression of Umbelopsis ramanniana diacylglycerol O-acyltransferase 2A in seed increases oil in soybean without reduction of other important yield parameters. This increase in oil can potentially add over $1 billion to the annual value of soybean crops.

<i>Glomus macrocarpum</i> Species of fungus

Glomus macrocarpum is a vesicular-arbuscular endomycorrhizal plant pathogen in the Glomeraceae family of fungi. Also occasionally known as Endogone macrocarpa, G. macrocarpum is pathogenic to multiple plants, including tobacco and chili plants. G. macrocarpum was first discovered in the French woodlands by the Tulsane brothers in the early to mid 1800s. Their first known description of G. macrocarpum was published in the New Italian Botanical Journal in 1845. G. macrocarpum has since been documented in over 26 countries, including Australia, China, and Japan for example. G. macrocarpum is frequently found in grassy meadows, forests, greenhouses, and fruit orchards. It is known for its small, round-edged, and light brown to yellow-brown sporocarp. G. macrocarpum is sometimes known as the Glomerales truffle.

<span class="mw-page-title-main">Common symbiosis signaling pathway</span>

The common symbiosis signaling pathway (CSSP) is a signaling cascade in plants that allows them to interact with symbiotic microbes. It corresponds to an ancestral pathway that plants use to interact with arbuscular mycorrhizal fungi (AMF). It is known as "common" because different evolutionary younger symbioses also use this pathway, notably the root nodule symbiosis with nitrogen-fixing rhizobia bacteria. The pathway is activated by both Nod-factor perception, as well as by Myc-factor perception that are released from AMF. The pathway is distinguished from the pathogen recognition pathways, but may have some common receptors involved in both pathogen recognition as well as CSSP. A recent work by Kevin Cope and colleagues showed that ectomycorrhizae also uses CSSP components such as Myc-factor recognition.
