What are Deuteromycetes? What is exception in deuteromycetes for sexual reproduction ?
Answers
Answer:
Most Deuteromycota have a well-developed, septate mycelium with distinct conidiophores but some have a unicellular thallus. With the exception of one group, all members reproduce by means of special spores known as conidia. ... Deuteromycetes are: 1. Ascomycetes with no sexual stage
Reproduction of Deuteromycota is strictly asexual, occuring mainly by production of asexual conidiospores. Some hyphae may recombine and form heterokaryotic hyphae. Genetic recombination is known to take place between the different nuclei.
Imperfect fungi have a large impact on everyday human life. The food industry relies on them for ripening some cheeses. The blue veins in Roquefort cheese and the white crust on Camembert are the result of fungal growth. The antibiotic penicillin was originally discovered on an overgrown Petri plate on which a colony of Penicillium fungi killed the bacterial growth surrounding it. Many imperfect fungi cause serious diseases, either directly as parasites (which infect both plants and humans), or as producers of potent toxic compounds, as seen in the aflatoxins released by fungi of the genus Aspergillus.
