“…The VEM approach led to the detection of the first whitefly-transmitted carlavirus (CpMMV Florida) in North America. This virus has been reported in a wide range of geographical areas including Africa, India, Asia, the Middle East, and South America, where it can infect and negatively impact important food crops [19] – [22] , [41] – [43] . The host range of the CpMMV Florida isolate includes members of the Chenopodeaceae and Fabaceae families that have been previously reported as either natural or experimental hosts for CpMMV isolates from different regions.…”

Whiteflies from the Bemisia tabaci species complex have the ability to transmit a large number of plant viruses and are some of the most detrimental pests in agriculture. Although whiteflies are known to transmit both DNA and RNA viruses, most of the diversity has been recorded for the former, specifically for the Begomovirus genus. This study investigated the total diversity of DNA and RNA viruses found in whiteflies collected from a single site in Florida to evaluate if there are additional, previously undetected viral types within the B. tabaci vector. Metagenomic analysis of viral DNA extracted from the whiteflies only resulted in the detection of begomoviruses. In contrast, whiteflies contained sequences similar to RNA viruses from divergent groups, with a diversity that extends beyond currently described viruses. The metagenomic analysis of whiteflies also led to the first report of a whitefly-transmitted RNA virus similar to Cowpea mild mottle virus (CpMMV Florida) (genus Carlavirus) in North America. Further investigation resulted in the detection of CpMMV Florida in native and cultivated plants growing near the original field site of whitefly collection and determination of its experimental host range. Analysis of complete CpMMV Florida genomes recovered from whiteflies and plants suggests that the current classification criteria for carlaviruses need to be reevaluated. Overall, metagenomic analysis supports that DNA plant viruses carried by B. tabaci are dominated by begomoviruses, whereas significantly less is known about RNA viruses present in this damaging insect vector.

“…However, false negatives can also occur, as we unexpectedly observed with three samples corresponding to BGMV isolates that could not be detected using the specific probe, probably due to the poor quality of the extracted DNA or a low viral titer [1]. On the other hand, only 21.2% of the symptomatic common bean samples were infected with begomoviruses; therefore, the remaining samples could have been infected by other viruses [1,19] or affected by herbicides [21]. In this work, we detected and characterized BBSV, a new begomovirus infecting common bean crops in Argentina.…”

Biological and molecular characterization of bean bushy stunt virus, a novel bipartite begomovirus infecting common bean in northwestern Argentina

et al. 2021

Common bean plants (Phaseolus vulgaris L.) showing different virus-like symptoms were collected in northwestern Argentina. Dot-blot hybridization tests showed that the begomoviruses bean golden mosaic virus and tomato yellow vein streak virus were the most prevalent, but they also revealed the presence of unknown begomoviruses. The complete genome sequence of one of these unknown begomoviruses was determined. Sequence analysis showed that the virus is a typical New World begomovirus, for which the name "bean bushy stunt virus" (BBSV) is proposed. Biological assays based on biolistic inoculations showed that BBSV induced leaf roll and stunting symptoms similar to those observed in the field-collected common bean sample.

“…The symptoms induced by BCMV in the common bean include leaf mosaic, chlorosis, deformation and etiolation, plant retardation, local or systematic necrosis, and even wholeplant death [91][92][93][94][95][96]. The symptoms are mainly affected by three factors: host plants, environmental conditions, and viral strains [97][98][99][100] (Figure 1). BCMV can seriously affect the common bean's yield reduction or even total failure.…”

Bean common mosaic disease is one of the most destructive diseases of the common bean, which is one of the most important legumes worldwide. It is caused by two closely related potyviruses: bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV). Both viruses have spread to all the common bean-growing areas worldwide and have become a major challenge in bean production. In this review, we summarized the biology and diversity of BCMV and BCMNV, discussed the current knowledge on the resistance genes of BCMV, and finally pointed out the future prospects for the control of bean common mosaic disease.
