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 [...]
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 classification of uredinales. Family Pucciniaceae: This is the largest and most important family of the order Uredinales. Rust fungi included in this family infect numerous valuable agricultural plants and cause enormous loss to crops. Members of the family are manifold and the complexities, owing to polymorphism, heteroecism and biologic specialization are very [...]
