Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found in a wide variety of organic substances, including "mature fruits and vegetables", [2] jellies, syrups, leather, bread, peanuts, and tobacco.
Later stages of disease have external masses of mycelium among clumps of black sporangia, dispersing spores abiotically, and by birds. The diseased heads can completely rot in 3 to 7 days. [5] Rhizopus microsporus has been found to be the species involved in Rhizopus Ear Rot of maize as well. This is characterized by small spotted sporangia ...
[1] [2] The most common are Rhizopus soft rot (Rhizopus stolonifer), bacterial soft rot (Erwinia chrysanthemii), Fusarium root rot (Fusarium solani), Fusarium surface rot (Fusarium oxysporum), and black rot (Ceratocystis fimbriata). R. stolonifer is a problematic pathogen as it infects fresh wounds occurring during packing and shipping. There ...
Rhizopus stolonifer is commonly known as black bread mold. [1] It is a member of Zygomycota and considered the most important species in the genus Rhizopus . [ 2 ] It is one of the most common fungi in the world and has a global distribution although it is most commonly found in tropical and subtropical regions. [ 3 ]
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] Informally known as zygomycetes I, Mucoromycota includes Mucoromycotina, Mortierellomycotina, and Glomeromycotina, and consists of mainly mycorrhizal fungi, root endophytes, and plant decomposers. [3]
Mucor spores or sporangiospores can be simple or branched and form apical, globular sporangia that are supported and elevated by a column-shaped columella. Mucor species can be differentiated from molds of the genera Absidia, Rhizomucor, and Rhizopus by the shape and insertion of the columella, and the lack of stolons and rhizoids.
Rhizopus oryzae is a filamentous heterothallic microfungus that occurs as a saprotroph in soil, dung, and rotting vegetation. This species is very similar to Rhizopus stolonifer , but it can be distinguished by its smaller sporangia and air-dispersed sporangiospores.
Mucor mucedo, commonly known as the common pinmould, [1] is a fungal plant pathogen and member of the phylum Mucoromycota and the genus Mucor. [2] Commonly found on soil, dung, water, plants and moist foods, Mucor mucedo is a saprotrophic fungus found world-wide with 85 known strains.
