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. The asexual reproduction by formation of spores is very common in Mucor. Mucor, habitat, structure, reproduction Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Kingdom Plantae Asexual reproduction in plants occurs through vegetative propagation and apomixis. If you continue browsing the site, you agree to the use of cookies on this website. The sporangiophore of Mucor is branched. At the time of secual reproduction two hyphae from mycelia of different strains grow towards each other. Mucormycosis mainly affects people who have health problems or take medicines that lower the body’s ability to fight germs and sickness. Reproduction in Mucor takes place by isogametes. Asexual reproduction in Mucor takes place through fragmentation and through sporangiophore formation. Microscopic Features. How Does Yeast Reproduce. Some species are homothallic where zygospores are formed in cultures derived from a single sporangiospore. » Zygomycetes: Rhizopus oryzae, Mucor mucedo. Sexual reproduction occurs when two similar gametangia conjugate to produce a zygospore. The genus Mucor belongs to the zygomycotan order Mucorales. Yeasts undergo both asexual reproduction and sexual reproduction. Mucor reproduces through sexual and asexual reproduction. These molds live throughout the environment. 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. While asexual reproduction takes place by the formation of spores, sexual reproduction takes place by conjugation of isogametes. Reproduction : This takes place vegetatively, asexually and sexually. Mucor reproduce both in sexual and asexual method. Such hyphae are called progametangia. Nonseptate or sparsely septate, broad (6-15 µm) hyphae, sporangiophores, sporangia, and spores are visualized. Asexual reproduction is characterized by the formation of one to many sporangiospores in a mitosporangium. Mucor mucedo (genus species) use asexual reproduction. Upon maturity, the sporangiophore develops into a … However, diploid yeast cells consist of two sets of homologous chromosomes. 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. Male and female mycelia are morphological identical by physiologically different, thus represented by + (positive) and – (negative) strains. In some cases, mucor invades arteries whereby blood clots can form, blocking vessels to the brain. Mucormycosis (previously called zygomycosis) is a serious but rare fungal infection caused by a group of molds called mucormycetes. Very few plant species reproduce strictly through asexual modes. 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). Haploid yeast cells consist of a single set of homologous chromosomes within the nucleus. When erect hyphal sporangiophores are formed. There are two types of cells in a yeast population: haploid cells and diploid cells. Vegetative reproduction : Fragmentation of the mycelium results in the multiplication of the fungus by developing fresh stock of mycelia. Reproduction. Mucor indicus is an aromatic species and may grow at temperatures as high as 40°C. Mucor is dioecious and heterothallic.
