Sweet potato mild mottle virus (SPMMV) is a plant pathogenic virus of the family Potyviridae.
Sweet potato mild mottle virus (or SPMMV) has a large host range. This is uncommon for potyviruses, making SPMMV a divergent species of potyviruses.[1] SPMMV hosts include 45 different species in 14 different plant families.[2] The naturally occurring host, and namesake for the virus is Ipomoea batatas (sweet potato). Even though SPMMV is found naturally in sweet potato, scientists have been able to experimentally transmit the virus to different species including beets, sowbane, devil’s snare, makhmali, tomato, tobacco, petunia, and zinna.[3]
Some common symptoms seen in SPMMV hosts include mild leaf mottling, which is characterized by irregular patterns of marks, patches, spots, and streaks of different colors on host leaves. Also, stunting and dwarfing of the plant is common.[4] Some hosts even have venial chlorosis.[5][6] Overall, plant growth is very poor in hosts with SPMMV.[2]
