Phylum :Basidiomycota. • General characters: • The sexual reproduction produce basidiospores. • No flagellate cells are present. • Dikaryotic phase long dikaryotic mycelium. (may have clamp connection). • Presence of dolipore septum • (septated mycelium).
5.Basidiomycota: parasites rust fungi smut fungi Saprophytes. 6. Cell wall contain high amount of chitin. 7. Forming marcroscopic fruiting bodies. 8. Asexual reproduction by conidia,chlamdospores
The dolipare septum: Found in all basidiomycota except the rust fungi It consist of central preforated swelling over which there is a pore cap The dolipare septum regulates the passage of nuclei and organelles from one cell to another by opining and closing
The clamp connection: Found in all dikaryotic mycelia of basidiomycota except for most uredinomycetes
The basidium: The basidium is the organ in which karyogamy and meiosis take place, result in formation of 4basidiospores externally on the basidium. Types of basidia phragmobasidium holiobasidium teliobasidium
Diplodization or dikaryotization: Is the process in which a primary mycelium converted into secondary myclium.
Class:Urediniomycetes General characters: • The mycelium has no clamp connection or dolipore septum. • Obligate parasites causing rust disease. • Heteroeious( require two different species of plant host to complete life cycle). • Heterothalic(have two diffrenet mating types -.+). • Sexual reproduction takes place by spermatization between spermatia and receptive hypae. • Life cycle is very complex.
Puccinia : Causing rust disease. • Plant Health Management Fungicide Application: The list of compounds labeled for rust control includes: chlorothalonil, chlorothalonil + fenarimol, chlorothalonil + thiophanate-methyl, cyproconazole, mancozeb, thiophanate-methyl + mancozeb, propiconazole, triadimefon, and thiram + triadimefon.
