Molecular diversity and coat protein expression of Sweet potato leaf curl virus
… management program. The variability among begomoviruses obtained from 11 sweetpotato genotypes was evaluated through the analysis of the nucleotide sequence of a fragment of the replication-associated protein gene (AC1). Ten of these begomoviruses were closely related to SPLCV and one was …

Investigations of the molecular determinants of maize streak virus replication
… region has been well characterised for the begomoviruses and to some extent the curtoviruses; however, this interaction in the mastreviruses, and in particular maize streak virus (MSV), has yet to be fully explored. A theoretical model has been proposed based on sequence data and informed by …

Molecular characterization of viruses infecting potato and vegetables in Iraq
… performed to screen samples for potyviruses, begomoviruses, carlaviruses, tombusviruses, potexviruses, cucumoviruses, tobamoviruses and alfamoviruses. Circular DNA viruses were screened by rolling circle amplification (RCA). Products resulting from PCR/RT-PCR and RCA were cloned and sequenced …

Molecular diagnostics, genetic diversity and generating infectious clones for cassava brown streak viruses
… laboratories. Mixed infections of cassava mosaic begomoviruses (CMBs) that cause cassava mosaic disease (CMD), CBSV and CBSUV have become more common with the recent spread of CBSD at mid-altitudes. A multiplex PCR for the simultaneous detection of viruses that cause both diseases, the first of …

Incidence, Distribution and Characteristics of Major Tomato Leaf Curl and Mosaic Virus Diseases in Uganda
… used. TYLCV-UG and ToLCV-UG homology with other begomoviruses, and their vector (Bemisia tabaci) relationship were studied. Major symptoms observed on tomato included leaf curl, mosaic and mottling, in descending order of importance. Ribonucleic acid viruses, i.e. Tomato mosaic virus (ToMV), …

Phylogeography of the Asia Ii and the Americas Major Clades of the Bemisia Tabaci Sibling Species Group
… oxidase I gene. B. tabaci is the only vector of begomoviruses; it transmits the complex of viruses that cause the cotton leaf curl disease, which has rapidly spread from Pakistan to the Philippines, at southeast of Asia, in the last decade. The study of B. tabaci mitotypes has been limited to …
