It can be found in tropical and subtropical regions primarily in India, but closely related species have also been detected in countries such as China, Malaysia, Nigeria and South Korea. [2] This virus is transmitted by an insect vector from the family Aleyrodidae and order Hemiptera, the whitefly Bemisia tabaci. PaLCuV has been responsible for ...
Tomato yellow leaf curl virus (TYLCV) is a DNA virus from the genus Begomovirus and the family Geminiviridae.TYLCV causes the most destructive disease of tomato, and it can be found in tropical and subtropical regions causing severe economic losses.
Pepper leaf curl virus (PepLCV) is a DNA virus from the genus Begomovirus and the family Geminiviridae.PepLCV causes severe disease especially in pepper (Capsicum spp.).It can be found in tropical and subtropical regions such as Thailand and India, but has also been detected in countries such as the United States and Nigeria.
Chilli leaf curl virus (ChiLCV) is a DNA virus from the genus Begomovirus and the family Geminiviridae. ChiLCV causes severe disease especially in pepper ( Capsicum spp. ), but also affects other crops such as tomato ( Solanum lycopersicum ). [ 1 ]
The leaves begin to wilt and may buckle at the base of the petiole. As the disease progresses, younger leaves are affected, turn yellow and crumple and the whole canopy begins to consist of dead or dying leaves. [5] The leaf symptoms of Fusarium wilt can be confused with those of Xanthomonas wilt.
Most commonly Cephaleuros virescens is identified by the leaf spots it causes. Theses leaf spots are an orange-brown rust in color and usually occur entirely on the upper leaf surface, although leaf spots on the undersides of infected leaves have been reported. The spots are fuzzy in texture and approximately 2 cm (0.8 in) in diameter. [2]
Chlorosis spreads to older leaves followed by necrosis [4] and water-soaked spots appear on the petioles and stems. [5] In diseased plants, flowers and fruit are rarely produced and during advanced stages of the disease, the papaya plant becomes denuded except for a few stunted leaves that remain at the apex.

Cassava mosaic virus is the common name used to refer to any of eleven different species of plant pathogenic virus in the genus Begomovirus. African cassava mosaic virus (ACMV), East African cassava mosaic virus (EACMV), and South African cassava mosaic virus (SACMV) are distinct species of circular single-stranded DNA viruses which are transmitted by whiteflies and primarily infect cassava ...
