Vegetative reproduction : Fragmentation of the mycelium results in the multiplication of the fungus by developing fresh stock of mycelia. These molds live throughout the environment. The genus Mucor belongs to the zygomycotan order Mucorales. A majority of them exhibit an alternation … Mucor, habitat, structure, reproduction Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Mucormycosis mainly affects people who have health problems or take medicines that lower the body’s ability to fight germs and sickness. Reproduction : This takes place vegetatively, asexually and sexually. The asexual reproduction by formation of spores is very common in Mucor. Mucor reproduces through sexual and asexual reproduction. Microscopic Features. These fungi are characterized by eucarpic, mostly coenocytic thalli containing haploid nuclei. If you continue browsing the site, you agree to the use of cookies on this website. Kingdom Plantae Asexual reproduction in plants occurs through vegetative propagation and apomixis. Mucormycosis is a disease brought about by inhaling spores produced by mucor molds. The fungal infection typically causes a reaction in the eyes and nose, but the most common site for serious infection is the lungs, sinuses, and brain. There are two types of cells in a yeast population: haploid cells and diploid cells. Yeasts undergo both asexual reproduction and sexual reproduction. » Zygomycetes: Rhizopus oryzae, Mucor mucedo. The tip of the sporangiophore swells to form a globose sporangium that contains uninucleate, haploid sporangiospores.An extension of the sporangiophore called the columella protrudes into the sporangium. Haploid yeast cells consist of a single set of homologous chromosomes within the nucleus. Mucor is dioecious and heterothallic. Asexual reproduction in Mucor takes place through fragmentation and through sporangiophore formation. Such hyphae are called progametangia. How Does Yeast Reproduce. Asexual reproduction is characterized by the formation of one to many sporangiospores in a mitosporangium. In some cases, mucor invades arteries whereby blood clots can form, blocking vessels to the brain. Mucor racemosus and Mucor ramosissimus, on the other hand, grow poorly or do not grow at all at 37°C. Mucormycosis (previously called zygomycosis) is a serious but rare fungal infection caused by a group of molds called mucormycetes. Male and female mycelia are morphological identical by physiologically different, thus represented by + (positive) and – (negative) strains. Mucor reproduce both in sexual and asexual method. Nonseptate or sparsely septate, broad (6-15 µm) hyphae, sporangiophores, sporangia, and spores are visualized. The sporangiophore of Mucor is branched. Mucor mucedo (genus species) use asexual reproduction. Sexual reproduction occurs when two similar gametangia conjugate to produce a zygospore. Mucor species are able to reproduce both sexually and asexually, with asexual reproduction as the most common method of reproduction, which results in the production of aplanospores (Reddy, 1996). At the time of secual reproduction two hyphae from mycelia of different strains grow towards each other. Upon maturity, the sporangiophore develops into a … Reproduction in Mucor takes place by isogametes. Very few plant species reproduce strictly through asexual modes. However, diploid yeast cells consist of two sets of homologous chromosomes. Reproduction. Some species are homothallic where zygospores are formed in cultures derived from a single sporangiospore. When erect hyphal sporangiophores are formed. While asexual reproduction takes place by the formation of spores, sexual reproduction takes place by conjugation of isogametes. Mucor indicus is an aromatic species and may grow at temperatures as high as 40°C.
