dc.description.abstractEnAn emerging systemic necrosis disease of corn salad was first observed in the Nantes region of France in the late 2000’s. Classical virology and high-throughput sequencing approaches demonstrated that the disease is associated with four different necroviruses, tobacco necrosis virus A (TNVA), tobacco necrosis virus D (TNVD), olive mild mosaic virus (OMMV) and a novel recombinant Alphanecrovirus for which the name corn salad necrosis virus (CSNV) is proposed. Satellite tobacco necrosis virus (STNV) was also frequently observed. Koch’s postulates were completed for all four agents, each one alone being able to cause systemic necrosis of varying severity in corn salad. OMMV was the most frequently observed virus and causes the most severe symptoms. TNVA was the second, both in terms of prevalence and symptom severity while TNVD and CSNV were only rarely observed and cause the less severe symptoms. The emergence of this systemic disease may have been favoured by the short and repeated cropping cycles used for corn salad, possibly allowing the selection of necrovirus isolates with an improved ability to systemically invade this specialty crop.
