First report of sweet potato chlorotic stunt virus in Greece
In Southern Greece, typical symptoms of sweet potato virus disease such as purple ringspots, distortion and crinkling of the leaves were observed in 2018 on a sweet potato (Ipomea batatas) crop located in Messinia. High-throughout sequencing (HTS) analysis of symptomatic leaves revealed the presence of 7 viruses: sweet potato feathery mottle virus (Potyvirus, SPFMV), sweet potato chlorotic stunt virus (Crinivirus, SPCSV, EU Annexes), sweet potato virus C (Potyvirus, SPVC), sweet potato virus G (Potyvirus, SPVG), sweet potato virus 2 (Potyvirus, SPV2), sweet potato leaf curl virus (Begomovirus, SPLCV, EU Annexes as Begomovirus) and sweet potato pakakuy virus (Badnavirus, SPPV). These viruses were again detected in symptomatic plants in another field in the same region in 2020. SPPV, SPLCV and SPFMV were also detected in a field with asymptomatic plants. This is the first report of these seven viruses in Greece.
