What is sclerotia plant pathology?
What is sclerotia plant pathology?
sclerotiorum can also be known as cottony rot, watery soft rot, stem rot, drop, crown rot and blossom blight. A key characteristic of this pathogen is its ability to produce black resting structures known as sclerotia and white fuzzy growths of mycelium on the plant it infects.
What is sclerotia in biology?
A sclerotium (/skləˈroʊʃəm/), plural sclerotia (/skləˈroʊʃə/), is a compact mass of hardened fungal mycelium containing food reserves. One role of sclerotia is to survive environmental extremes. In some higher fungi such as ergot, sclerotia become detached and remain dormant until favorable growth conditions return.
What is the scientific name of stem rot?
Magnaporthe salvinii (stem rot)

Are truffles Sclerotium?
Magic truffles are the sclerotia of Psilocybin mushrooms that are not technically the same as “mushrooms”. They are masses of mycelium that contain the hallucinogenic chemicals psilocybin and psilocin.
Where is Sclerotinia sclerotiorum found?
moist
Host Range and Distribution Sclerotinia sclerotiorum has a world-wide distribution, however it is most prevalent in cool moist regions (2). The fungus causes disease on such crops as tobacco, vegetables, and ornamentals.
Is mold a fruiting body?
Cellular slime molds live as individual cells and come together in times of food shortage to form a reproductive structure called a fruiting body.
What is white mold?
White mold is a powdery fungus made up of different fungal species that can appear white, green, or grey, depending on the type of surface it has infected. Like most molds, white mold thrives in areas with high moisture like showers, crawl spaces, basements, and leaky walls.
What phylum is white mold?
Sac fungi
Sclerotinia sclerotiorum/Phylum
Where does sclerotia spend most of its life cycle?
Approximately 90% of the life cycle of Sclerotinia species is spent in soil as sclerotia. At certain times of the year, depending on the inherent nature of the fungus and various environmental factors, the sclerotia germinate and form either mycelium which can infect a host, or an apothecium.
Where does sclerotia germinate and form apothecium?
At certain times of the year, depending on the inherent nature of the fungus and various environmental factors, the sclerotia germinate and form either mycelium which can infect a host, or an apothecium. Infection of host plants by mycelium can occur at or beneath the soil-line.
Where does the sclerotiorum live in the world?
S. sclerotiorum is geographically cosmopolitan and has a broad ecological distribution, though it is most common in temperate regions. It was originally believed to occur only in cool, moist areas, but is now known to occur in hot, dry areas as well.
What kind of reproductive structures does Sclerotinia produce?
The cottony mycelium usually produces numerous sclerotia, black seed-like reproductive structures, a reliable diagnostic sign of Sclerotinia (these usually do not form until after host death).
