Geographical distribution, genetic studies and vector transmission of alfalfa enamovirus-1 infecting alfalfa crop in Argentina

Alfalfa (Medicago sativa L.) growing areas of Argentina were surveyed between 2010 and 2018 to determine the geographical distribution and analyse the genetic diversity among alfalfa enamovirus-1 (AEV-1) isolates. The virus was detected in all 17 surveyed alfalfa-producing provinces, with a prevalen...

description Alfalfa (Medicago sativa L.) growing areas of Argentina were surveyed between 2010 and 2018 to determine the geographical distribution and analyse the genetic diversity among alfalfa enamovirus-1 (AEV-1) isolates. The virus was detected in all 17 surveyed alfalfa-producing provinces, with a prevalence of 64%. The plant virus AEV-1 is widely distributed in the country, and its transmission vector has been unknown until now. Here we show that the black aphid Aphis craccivora can transmit AEV-1. The CP sequence identity among 16 AEV-1 isolates from Argentina was from 98 to 100% and from 98.9 to 100% at nucleotide and amino acid levels, respectively, indicating a low level of sequence variation among these isolates. The phylogenetic analysis based on the complete nucleotide sequence of the CP gene indicated that AEV-1 isolates are closely related and clustered in a monophyletic group. These results suggest that AEV-1 has spread very recently in Argentina. In the present study, we report the geographical distribution of AEV-1 in the main alfalfa-growing areas of Argentina and, for the first time, identify an insect vector and describe the CP gene diversity of an enamovirus worldwide.
