In October 2011, sweet potato (Ipomoea batatas) mother plants (mainly cv. Georgia
Jet) in Israel suffered an epidemic of sweet potato virus disease (SPVD). The plants were of
poor appearance, grew feebly and showed strong leaf malformation, mosaic, purpling,
chlorosis, cupping, vein yellowing and occasional feathery mottle symptoms. SPVD is the
result of synergism between Sweet potato chlorotic stunt virus (SPCSV, genus Crinivirus)
and either Sweet potato feathery mottle virus (SPFMV, genus Potyvirus) or Sweet potato mild
mottle virus (SPMMV, genus Ipomovirus). PCR assays and sequence analysis revealed the
causal agent as Sweet potato virus C (SPVC). SPVC is a distant variant of SPFMV that has
been known for many years in Israel based on symptom appearance and immunological
tests. Of 170 field samples (each composed of 25 leaf samples) collected from all four...
