Mottle or mottling is the appearance of uneven spots on plants or the skin of animals. In plants, mottling usually consists of yellowish spots on plants, and is usually a sign of disease or malnutrition.[1] Many plant viruses cause mottling, some examples being:
Mottling is sometimes used to describe uneven discolored patches on the skin of humans as a result of cutaneous ischemia (lowered blood flow to the surfaces of the skin) or Herpes zoster infections.[2] In animals, mottling may be a sign of disease, but may also be a hereditary trait, such as seen with the champagne and leopard complex genes in horses.
Mottles can also refer to discoloration in processed food, such as butter.[3]
