Begomovirus populations in single plants are complex and may include both well-adapted and poorly-adapted viruses. Virus Res 2023; 323:198969. [PMID: 36257487 PMCID: PMC10194161 DOI: 10.1016/j.virusres.2022.198969] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 10/10/2022] [Accepted: 10/13/2022] [Indexed: 11/05/2022]
Abstract
Begomoviruses (single-stranded DNA plant viruses transmitted by whiteflies) are economically important pathogens causing epidemics worldwide. Tomato-infecting begomoviruses emerged in Brazil in the 1990's following the introduction of Bemisia tabaci Middle East-Asia Minor 1. It is believed that these viruses evolved from indigenous viruses infecting non-cultivated hosts. However, tomato-infecting viruses are rarely found in non-cultivated hosts, and vice-versa. It is possible that viral populations in a given host are composed primarily of viruses which are well adapted to this host, but also include a small proportion of poorly adapted viruses. Following transfer to a new host, the composition of the viral population would shift rapidly, with the viruses which are better adapted to the new host becoming predominant. To test this hypothesis, we collected tomato and Sida plants growing next to each other at two locations in 2014 and 2018. Total DNA was extracted from tomato and Sida samples from each location and year and used as a template for high-throughput sequencing. Reads were mapped following a highly stringent set of criteria. For the 2014 samples, >98% of the Sida reads mapped to Sida micrantha mosaic virus (SiMMV), but 0.1% of the reads mapped to tomato severe rugose virus (ToSRV). Conversely, >99% of the tomato reads mapped to ToSRV, with 0.18% mapping to SiMMV. For the 2018 samples, 41% of the Sida reads mapped to three Sida-adapted viruses and 0.1% of the reads mapped to ToSRV, while 99.9% of the tomato reads mapped to ToSRV. These results are consistent with the hypothesis that viral populations in a single plant are composed primarily of the virus that is better adapted to the host but also include a small proportion of viruses that are poorly adapted.

Abstract
Background Begomoviruses are circular single-stranded DNA plant viruses that cause economic losses worldwide. Weeds have been pointed out as reservoirs for many begomoviruses species, especially from members of the Sida and Malvastrum genera. These weeds have the ability to host multiple begomoviruses species simultaneously, which can lead to the emergence of new viral species that can spread to commercial crops. Additionally, begomoviruses have a natural tendency to recombine, resulting in the emergence of new variants and species. Methods To explore the begomoviruses biodiversity in weeds from genera Sida and Malvastrum in Colima, México, we collected symptomatic plants from these genera throughout the state. To identify BGVs infecting weeds, we performed circular DNA genomics (circomics) using the Illumina platform. Contig annotation was conducted with the BLASTn tool using the GenBank nucleotide "nr" database. We corroborated by PCR the presence of begomoviruses in weeds samples and isolated and sequenced the complete genome of a probable new species of begomovirus using the Sanger method. The demarcation process for new species determination followed the International Committee on Taxonomy of Viruses criteria. Phylogenetic and recombination analyses were implemented to infer the evolutionary relationship of the new virus. Results We identified a new begomovirus species from sida and malvastrum plants that has the ability to infect Cucumis sativus L. According to our findings, the novel species Sida chlorotic leaf virus is the result of a recombination event between one member of the group known as the Squash leaf curl virus (SLCV) clade and another from the Abutilon mosaic virus (AbMV) clade. Additionally, we isolated three previously identified begomoviruses species, two of which infected commercial crops: okra (Okra yellow mosaic Mexico virus) and cucumber (Cucumber chlorotic leaf virus). Conclusion These findings support the idea that weeds act as begomovirus reservoirs and play essential roles in begomovirus biodiversity. Therefore, controlling their populations near commercial crops must be considered in order to avoid the harmful effects of these phytopathogens and thus increase agricultural efficiency, ensuring food and nutritional security.

Abstract
Viruses constitute the largest group of emerging pathogens, and geminiviruses (plant viruses with circular, single-stranded DNA genomes) are the major group of emerging plant viruses. With their high potential for genetic variation due to mutation and recombination, their efficient spread by vectors, and their wide host range as a group, including both wild and cultivated hosts, geminiviruses are attractive models for the study of the evolutionary and ecological factors driving virus emergence. Studies on the epidemiological features of geminivirus diseases have traditionally focused primarily on crop plants. Nevertheless, knowledge of geminivirus infection in wild plants, and especially at the interface between wild and cultivated plants, is necessary to provide a complete view of their ecology, evolution, and emergence. In this review, we address the most relevant aspects of geminivirus variability and evolution in wild and crop plants and geminiviruses' potential to emerge in crops.

Abstract
A new begomovirus infecting Croton hirtus (Euphorbiaceae) from Colombia has been characterized. The complete DNA-A and DNA-B components were determined to be 2613 and 2551 nt in length, respectively, showing the typical genome organization of bipartite New World begomoviruses. DNA-A showed the highest nucleotide sequence identity (81.2%) to sida yellow mottle virus (JN411687), a begomovirus isolated from Sida rhombifolia in Cuba. Based on the current ICTV species demarcation criterion for the genus Begomovirus, we report a new member of this genus infecting C. hirtus. We propose that it be named Croton golden mosaic virus (CroGMV), based on the symptoms observed in the weed. Phylogenetic analysis revealed that CroGMV segregates into a single clade and has some relationship with viruses from Central America and the Caribbean. CroGMV is the first Croton-infecting bipartite begomovirus reported in the world.

Abstract
Deltasatellites are small noncoding DNA satellites associated with begomoviruses. The study presented here has investigated the biology of two deltasatellites found in wild malvaceous plants in the New World (NW). Infectious clones of two NW deltasatellites (from Malvastrum coromandelianum and Sidastrum micranthum) and associated begomoviruses were constructed. Infectivity in Nicotiana benthamiana and their natural malvaceous hosts was assessed. The NW deltasatellites were not able to spread autonomously in planta, whereas they were maintained by the associated bipartite begomovirus. Furthermore, NW deltasatellites were transreplicated by a monopartite NW begomovirus, tomato leaf deformation virus. However, they were not maintained by begomoviruses from the Old World (tomato yellow leaf curl virus, tomato yellow leaf curl Sardinia virus and African cassava mosaic virus) or a curtovirus (beet curly top virus). NW deltasatellites did not affect the symptoms induced by the helper viruses but in some cases reduced their accumulation. Moreover, one NW deltasatellite was shown to be transmitted by the whitefly Bemisia tabaci, the vector of its helper begomoviruses. These results confirm that these molecules are true satellites. The availability of infectious clones and the observation that NW deltasatellites reduced virus accumulation paves the way for further studies of the effect on their helper begomoviruses.

Abstract
Begomoviruses are whitefly-transmitted, single-stranded DNA viruses that cause serious infections in crop plants and are often also associated with non-cultivated plants. Here, we report the detection of two new begomoviruses in Pavonia sp. (Malvaceae). Sequence comparisons and phylogenetic analysis showed that these novel viruses are related to New World begomoviruses. The nucleotide sequences of the DNA-A of both viruses had the highest similarity to abutilon mosaic Bolivia virus (AbMBoV). Based on symptoms observed in the field and considering the host, we propose the names pavonia mosaic virus (PavMV) and pavonia yellow mosaic virus (PavYMV) for these two new begomoviruses.

Abstract
In the Dominican Republic (DO), jatropha plants with yellow mosaic symptoms are commonly observed in and around fields of various crop plants. Complete nucleotide sequences of DNA-A and DNA-B components of four bipartite begomovirus isolates associated with symptomatic jatropha plants collected from three geographical locations in the DO were determined. Sequence comparisons revealed highest identities (91 to 92%) with the DNA-A component of an isolate of Jatropha mosaic virus (JMV) from Jamaica, indicating that the bipartite begomovirus isolates from the DO are strains of JMV. When introduced into jatropha seedlings by particle bombardment, the cloned components of the JMV strains from the DO induced stunting and yellow mosaic, indistinguishable from symptoms observed in the field, thereby fulfilling Koch's postulates for the disease. The JMV strains also induced disease symptoms in Nicotiana benthamiana, tobacco, and several cultivars of common bean from the Andean gene pool, including one locally grown in the DO. Asymmetry in the infectivity and symptomatology of pseudorecombinants provided further support for the strain designation of the JMV isolates from the DO. Thus, JMV in the DO is a complex of genetically distinct strains that have undergone local evolution and have the potential to cause disease in crop plants.

Abstract
Begomoviruses are whitefly-transmitted, ssDNA plant viruses and are among the most damaging pathogens causing epidemics in economically important crops worldwide. Wild/non-cultivated plants play a crucial epidemiological role, acting as begomovirus reservoirs and as ‘mixing vessels' where recombination can occur. Previous work suggests a higher degree of genetic variability in begomovirus populations from non-cultivated hosts compared with cultivated hosts. To assess this supposed host effect on the genetic variability of begomovirus populations, cultivated (common bean, Phaseolus vulgaris, and lima bean, Phaseolus lunatus) and non-cultivated (Macroptilium lathyroides) legume hosts were sampled from two regions of Brazil. A total of 212 full-length DNA-A genome segments were sequenced from samples collected between 2005 and 2012, and populations of the begomoviruses Bean golden mosaic virus (BGMV) and Macroptilium yellow spot virus (MaYSV) were obtained. We found, for each begomovirus species, similar genetic variation between populations infecting cultivated and non-cultivated hosts, indicating that the presumed genetic variability of the host did not a priori affect viral variability. We observed a higher degree of genetic variation in isolates from MaYSV populations than BGMV populations, which was explained by numerous recombination events in MaYSV. MaYSV and BGMV showed distinct distributions of genetic variation, with the BGMV population (but not MaYSV) being structured by both host and geography.

Abstract
Tomato severe rugose virus (ToSRV) is the most important begomovirus species in Brazilian tomato production. Many weeds are associated with tomato, and some are hosts of begomoviruses. Only one species of weed, Nicandra physaloides, has been found to be infected with ToSRV. In this study, four weed species were investigated for their capacity to be infected by ToSRV and serve as a potential source of inoculum for tomato. Begomoviruses from naturally infected Crotalaria spp., Euphorbia heterophylla, N. physaloides, and Sida spp. were successfully transferred to tomato plants by biolistic inoculation. ToSRV was the major virus transferred to tomato. In contrast, other begomoviruses were transferred to weeds, such as Sida micrantha mosaic virus and Euphorbia yellow mosaic virus. Furthermore, a new strain of Sida micrantha mosaic virus is reported. We also confirmed that Crotalaria spp., E. heterophylla, and Sida spp. are infected with ToSRV but at low viral titers and in mixed infections with weed-infecting begomoviruses. Thus, it was demonstrated that weeds are potential sources of ToSRV for tomato in central Brazil.

Abstract
Begomoviruses are ssDNA plant viruses that cause serious epidemics in economically important crops worldwide. Non-cultivated plants also harbour many begomoviruses, and it is believed that these hosts may act as reservoirs and as mixing vessels where recombination may occur. Begomoviruses are notoriously recombination-prone, and also display nucleotide substitution rates equivalent to those of RNA viruses. In Brazil, several indigenous begomoviruses have been described infecting tomatoes following the introduction of a novel biotype of the whitefly vector in the mid-1990s. More recently, a number of viruses from non-cultivated hosts have also been described. Previous work has suggested that viruses infecting non-cultivated hosts have a higher degree of genetic variability compared with crop-infecting viruses. We intensively sampled cultivated and non-cultivated plants in similarly sized geographical areas known to harbour either the weed-infecting Macroptilium yellow spot virus (MaYSV) or the crop-infecting Tomato severe rugose virus (ToSRV), and compared the molecular evolution and population genetics of these two distantly related begomoviruses. The results reinforce the assertion that infection of non-cultivated plant species leads to higher levels of standing genetic variability, and indicate that recombination, not adaptive selection, explains the higher begomovirus variability in non-cultivated hosts.
