In this article we will discuss about the life cycle of phytophthora with the help of suitable diagrams. Mycelium of Phytophthora: It is profusely branched and consists of aseptate, hyaline, profusely branched, coenocytic, moderately thick hyphae about 4-8µ in diameter. The hyphal wall is approximately 0.1µ thick. It is electron transparent except for a thin, electron dense outer surface. Glucans [...]
In this article we will discuss about the life cycle of plasmopara with the help of suitable diagrams. Mycelium of Plasmopara: It is freely branched and coenocytic. The hyphae are numerous and vary in size. The fungus is strictly intercellular (Fig. 6.36 H). Some of the hyphae give off lateral outgrowths which penetrate the host cells and swell inside to [...]
In this article we will discuss about the life cycle of albugo with the help of suitable diagrams. Mycelium of Albugo: It is well developed and consists of branched, aseptate, coenocytic hyphae. The hyphae live and ramify in the intercellular spaces of the susceptible host tissue. The hyphal wall contains cellulose and not chitin. The hyphal protoplasm is granular and [...]
