Wheat streak mosaic virus coat protein N-terminus acts as a host-and strain-specific long-distance transporter . Virus coat proteins are used by Chinese wheat mosaic virus (CWMV) to disrupt autophagy and facilitate infection . Wheat curling mite vector competence is determined by the wheat streak mosaic virus coat protein . Insects, including mites, frequently leave behind a trail of debris. The mites leave behind debris high in the molecule chitin (chitin). Insect skeletons, like mites' exoskeletons, are largely composed of chitin as well. Chitin is a major dust mite allergen due to its binding properties.
