{{Short description|Subtype of a microorganism}}
In [[microbiology]] and [[virology]], the term '''variant''' or '''genetic variant''' is used to describe a subtype of a microorganism that is genetically distinct from a main strain, but not sufficiently different to be termed a distinct [[Strain (biology)|strain]]. A similar distinction is made in botany between different cultivated varieties of a [[species]] of plant, termed [[cultivar]]s.
