In this article we will discuss about:- 1. Characteristics of Basidiomycetes 2. Mating Systems of Basidiomycetes 6. Life Cycle Pattern. Characteristics of Basidiomycetes: The Basidiomycetes comprise the highest group of fungi which are often noticed conspicuously occurring in fields and forest areas. Most of them possess highly developed fructifications, known as basidiocarps which may be fleshy or woody. The fungi [...]
In this article we will discuss about:- 1. Introduction to Uredinales 2. Nuclear Cycle of Uridinales 3. Biological Specialization 4. Classification. Introduction to Uredinales: The Uredinales, or rust fungi comprise a large group of obligate parasites. They are called rusts, because of the rusty, reddish-brown colour of their spores, which are formed chiefly upon surfaces of host leaves and stems [...]
In this article we will discuss about the life cycle pattern of uredinales, explained with the help of suitable diagrams. In the usual course of the life cycle, as a result of infection of the host by sporidia, monokaryotic mycelia are produced which give rise to spermogonia (sing, spermogonium). The spermogonia are also known as pycnia (sing, pycnium). The spermogonia [...]
