Characteristics related to biosafety
The natural host range of PSbMV is limited to the Fabaceae family. The virus infects temperate pulses (chickpea, faba bean, field pea, lentil) other legumes (garden pea, narbon bean, lathyrus, vetch) and legume pastures. A number of PSbMV pathotypes have been recognised by their ability to infect a number of pea differential genotypes.
Pea seed-borne mosaic virus is distributed worldwide.
Field peas develop various degrees of stunting, downward curling of leaflets as well as a transient clearing and swelling of leaf veins in most cultivars. Infected plants may also produce distorted flowers, which often give rise to small distorted pods. Ovule development in affected pods may be uneven, with only one or two seeds being produced. Seed coats may split as the seeds mature. The symptoms on seeds result in brown rings and tan spots.
