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