[6][7] Its ssRNA genome has one large open reading frame (ORF) that encodes a polyprotein of ca.

[8] LYSV can be separated into three major types: S, L, and N based on variation in the P1 and coat protein (CP) regions of its genome and plant host species.

Three French garlic cultivars were tested against the virus, with result Messidrome had the least severe bulb weight loss (17%) compared to Germidour (26%) and Printanor (54%).

[11] All 87 samples of Vekan variety collected during field surveys in Czech Republic were tested to be LYSV-free, which highly indicated its resistance to the virus.

[12] Recently, Şampiyon and Perama were found to have the best reactions (most tolerant) among 15 onion cultivars tested in Turkey to mechanical inoculation of LYSV under greenhouse conditions.
