PSBMV0
Pea seed-borne mosaic virus is transmitted mechanically, by aphid vectors, and through seed. It primarily infects peas but can also be found in other legumes such as broad bean, lentil, and peavine. Infection can cause a range of symptoms, including mosaic patterns and curling of leaves, stunted growth, and distorted flowers or pods, though some infected seeds may appear symptomless. Seed transmission occurs only when plants are infected before flowering, and aphids spread the virus in a non-persistent manner, contributing to local outbreaks.

Pea seed is a pathway for PSbMV, which is transmitted to seeds only when plants are infected before flowering. Seed transmission rates vary with pea cultivar, virus strain, and timing of infection, ranging from 0–55%. Infected plants can show mild to severe mosaic and leaf curling, stunting, distorted flowers, and small or malformed pods, while some seeds may be symptomless or have reduced size with seed-coat scarring and cracking. In the field, the virus spreads between plants via aphids in a non-persistent manner.
