In this investigation, we investigated the biological function of the coat protein of wheat mosaic virus by employing the technique of domain search. The method was able to determine the mechanism of endocytosis in addition to the binding region of wheat mosaic virus for chitin, chitosan, and cellulose; the active region of cell wall degrading enzymes. According to the findings, wheat mosaic virus may be able to finish the process of virus transmission by adhering to chitin through the coat protein that it possesses. Chitin is a promising soil conditioner and a substantial component of the exoskeletons of many insects, including mites. Chitin is found in the exoskeletons of insects. If the wheat mosaic virus has attached itself to chitin/chitosan (or cellulose), it may be hiding in the soil or on insects. Phosphate fertilizers or pesticide diluents that contain phosphates have the potential to release the wheat mosaic virus, which will significantly increase the virus's ability to spread.
