Ustinaginales is also known and classified as the smut fungi. They are serious plant
parasitic
.
Morphology
Has a thick-walled resting spore (teliospore), known as the "brand" (burn) spore or chlamydospore.
Economic importance
They can infect corn plants (huitlacoche and sold canned for consumption in Latin America.
Sexual reproduction
Almost all Ustilaginales species share a
saprophitic yeast-like stage and a filamentous sexual stage that is required to parasitize a host.[6] The parasitic phase involves karyogamy, the process of fusing two haploid nuclei (present in haploid teliospore cells), followed by meiosis.[6] Each meiosis results in a septated basidium bearing four haploid basidiospores which can then proceed to yeast-like growth. During meiosis, genes are expressed that function in recombination and DNA repair.[6]
