First report of alfalfa leaf curl virus infecting alfalfa (Medicago sativa) in China.

Abstract

In April 2017 a survey was conducted to identify viruses infecting alfalfa (Medicago sativa) in a temperate region in Henan, China. From one field, 117 alfalfa leaf samples with symptoms of macular mosaic (n=26), mottle mosaic (21), etiolation (1), shrinkage (27), mosaic shrinkage (25), and dwarfism (17) were collected. The causal pathogen was isolated and identified as Alfalfa leaf curl virus based on nucleotide sequences. The obtained sequences were deposited in GenBank as accession number MK422438. This is thought to be the first report of Alfalfa leaf curl virus infecting alfalfa in China.
