Abstract

A virus is transmitted mechanically in the plant host. Potyviridae is a family of Potyvirus, consisting of a positive-sense RNA genome and filamentous particles. It has a single type of protein coat. Mostly, this virus is identified in Leguminosae and Solanaceae family. The plant virus is transmitted by mechanical inoculation and aphids. Chilli, cucurbits, potatoes, peas, tomatoes, and other plants were infected with the bean yellow mosaic virus, pea mosaic virus, bean yellow mosaic virus, sugarcane mosaic virus, and peanut mosaic virus. Thermal inactivation point, dilution endpoint, longevity in vitro, and longevity in vivo were used to identify the physical properties of a potyvirus. Several isolates mild and severe were collected in the chilli plant. The infected plant developed necrotic leaf spots and chlorotic symptoms.
