Tomato Leaf Curl New Delhi Virus in Zucchini crops in Iran

During a survey in 2020, in Hormozgan province, the following symptoms were observed in zucchini crops growing in the field: leaf curling, yellow mosaic, swelling of veins of young leaves, and shortening of internodes. Because of the importance of the Tomato Leaf Curl New Delhi Virus (ToLCNDV) in other crops in Iran, the presence of this virus in the plants was evaluated by PCR amplification of the coat protein gene. Sequence analysis confirmed ToLCNDV infection of the symptomatic plants. This is the first report of ToLCNDV in zucchini plants in Iran.
