Molecular detection and characterization of phytoplasma in association with begomovirus in eggplant

Acta virologica, 2018
The samples from eggplants showing mixed symptoms of little leaf and mosaic were collected from two districts (Mirzapur and Varanasi) of Uttar Pradesh, India. The total nucleic acid extracted from these samples was amplified by PCR using universal 16S rRNA primers specific to phytoplasma and primers specific to DNA-A-like sequence of begomovirus.

A New World begomovirus infecting Grapevine

, 2020
Abstract Grapevine ( Vitis L.), a deciduous woody vine, is a highly valuable agricultural crop. Grapevine, as other crops, is vulnerable to infectious pathogens. Several of them, including viruses, are a major threat to viticulture. Geminiviruses (family Geminiviridae ) are insect transmitted, small non-enveloped viruses, with circular single ...
