Wheat leaf rust (Puccinia triticina) is a fungal disease that affects wheat, barley, rye stems, leaves and grains. In temperate zones it is destructive on winter wheat because the pathogen overwinters.
Puccinia is a genus of fungi.All species in this genus are obligate plant pathogens and are known as rusts. [1] The genus contains about 4000 species. [2]The genus name of Puccinia is in honour of Tommaso Puccini (died 1735), who was an Italian doctor and botanist who taught anatomy at Hospital of Santa Maria Nuova in Florence.
Phoma-Coelomycetes Pycnidium. A pycnidium (plural pycnidia) is an asexual fruiting body produced by mitosporic fungi, for instance in the order Sphaeropsidales (Deuteromycota, Coelomycetes) or order Pleosporales (Ascomycota, Dothideomycetes).
The fungal ancestors of stem rust have infected grasses for millions of years and wheat crops for as long as they have been grown. [7] According to Jim Peterson, professor of wheat breeding and genetics at Oregon State University, "Stem rust destroyed more than 20% of U.S. wheat crops several times between 1917 and 1935, and losses reached 9% twice in the 1950s," with the last U.S. outbreak in ...
