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 [...]
The following points highlight the top eleven features of basidiomycetes. 1. The somatic phase consists of a well-developed, septate, filamentous mycelium which passes chiefly through two stages. (a) Primary mycelium: It is formed by the germination of a basidiospore and contains a single haploid (n) nucleus in each cell. It bears neither sex organs nor any basidia and basidiospores. It [...]
