Tomato leaf curl New Delhi virus (ToLCNDV)
This virus infects tomatoes, other solanaceous crops like potatoes, as well as other crops like cucurbits and cotton. It was originally described from India (in 1995) and has been subsequently found in other countries in southern Asia. Since 2012, a novel strain of ToLCNDV has been reported from Spain which has since spread to neighbouring countries (e.g. see Fortes et al. 2016). Yield losses can be severe, e.g. on cucurbits in Spain. The 2 circular and single-stranded DNA genomes have a size of about 2.7 kb.
Symptoms on tomatoes are similar to those caused by other tomato leaf curl viruses and include yellowing, vein clearing, severe leaf curling, twisting of stems and stunting. On cucurbits, symptoms have been described as leaf curling, vein swelling, and severe mosaic in young leaves, short internodes, and fruit skin roughness.
