Definition

Noun: 1. A taxonomic category in biology: "Genus Fusarium" is the scientific name for a large genus (a rank in biological classification below family and above species) of filamentous fungi. 2. A group of plant pathogens and saprobes: Most species within this genus are known as plant parasites, causing diseases like wilts, rots, and blights. Some species are also saprophytic, living on dead organic matter. 3. A cause of dry rot and human infection: Certain species can cause dry rot in plants and stored crops. In humans, some species (notably Fusarium solani) are opportunistic pathogens that can cause severe infections, including keratitis (inflammation of the cornea) which may lead to blindness.

Usage Examples

• Noun:
  • The plant pathologist identified the wilt disease as being caused by a species within the genus Fusarium.
  • Genus Fusarium contains many economically important pathogens that affect agricultural crops worldwide.
  • Laboratory analysis confirmed the fungal isolate belonged to the genus Fusarium.

Advanced Usage

• In taxonomic writing: The genus name is always italicized (), and when combined with "genus," it is written as "genus " or "the genus ."
• In clinical contexts: The term is used to specify the type of fungal infection, e.g., "a keratitis" or "an infection due to a member of the genus Fusarium."

Variants and Related Words

• Fusarium (n): The italicized form used alone to refer to the genus in scientific contexts (e.g., " species are ubiquitous in soil").
• Fusarial (adj): Relating to or caused by fungi of the genus Fusarium (e.g., fusarial wilt).
• Fusariosis (n): The disease condition caused by infection with a fungus.

Synonyms

• Form genus (in a specific mycological context): A taxonomic category for fungi classified primarily by asexual reproductive structures.
• Hyphomycete genus: Refers to its classification within the hyphomycetes, a group of fungi characterized by their mode of conidial (spore) production.

Related Phrases and Terms

• Fusarium wilt: A specific vascular disease of plants caused by fungi in this genus.
• Fusarium head blight: A disease of cereal crops, also known as scab.
• Fusarium keratitis: A serious fungal infection of the eye.

Noun

1. a form genus of mostly plant parasites some of which cause dry rot; in humans a species can cause inflammation of cornea leading to blindness
