Lettuce necrotic leaf curl virus
Lactuca sativa L.
Lettuce necrotic leaf curl virus (LNLCV) is a pathogen of the genus Torradovirus that causes plant deformation, necrosis, and stunting. Unlike other lettuce viruses, it is transmitted by lettuce aphids, primarily Nasonovia ribisnigri.
In the reference 7 varieties crop Lettuce, where this is mentioned in the description.
The LNLCV virus, described in 2011, is a specific pathogen affecting Lactuca sativa L. Its symptoms include moderate curling of leaf blades, the appearance of chlorotic spots along the fine veins of older leaves, and the development of necrotic lesions. Diseased plants are significantly stunted and develop a deformed appearance.
Although the term 'leaf curl' is often used to describe symptoms of Lettuce mosaic virus (LMV) infection, LNLCV is a distinct etiological entity. In breeding for protection against key viral deformations such as LMV, the resistance genes Mo2, Mo3, and Mo4, derived from Ithaca cultivars and the wild species Lactuca virosa, are employed; however, specialized commercial resistance genes for LNLCV are not widely available.
