“…Also, a leaf curl disease with symptoms typical of begomoviruses was observed in bean (P. vulgaris) at the Main Research Farm of the Indian Institute of Pulses Research, Kanpur, India (Kamaal et al, 2015) whereas Herrera-Vásquez et al (2016) detected begomoviruses in commercial tomato plots using both production systems (open field and greenhouse) in Panama with different degenerate primers. Just et al (2014) stated that, imported tomato fruits infected with Tomato yellow leaf curl virus (TYLCV) were identified on the market in northern Europe using paperbased FTA Classic Cards (Whatman), PCR and partial DNA sequence analysis.…”

The existence of Tomato yellow leaf curl virus (TYLCV) was figured out in different locations in AlAhsaa of Saudi Arabia. Polymerase chain reaction (PCR) results of samples collected showed that TYLCV existed in all locations. Using AVcore and ACcore primers, begomoviruses family were detected in symptomatic tomato plants and by using TYv2664 and TYc138 (specific primers for the detection of TYLCV), the results proved that the samples were infected with TYLCV. The lipid-soluble fraction of healthy and infected tomato leaves extract was compared using gas chromatography techniques. A total of 46 compounds were identified in both healthy and virus-infected leaf tissues; among which 37 metabolites were common between both samples and increased or decreased in concentration due to the virus attack. Nevertheless, eight compounds were exclusively detected in the infected samples with only one compound consumed and thus recognized only in the healthy samples. The classifications and roles of the identified metabolites were discussed from the point of view of plant defense mechanisms or virus resistance against plant defense.

“…Globally, beans are reported to be infected naturally by at least 83 viruses belonging to 24 genera of 12 families ( Table 1 ) [ 4 , 5 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ]. Among these viruses the potyvirids bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) are considered the most important ones.…”

Legumes, one of the most important sources of human food and animal feed, are known to be susceptible to a plethora of plant viruses. Many of these viruses cause diseases which severely impact legume production worldwide. The causal agents of some important virus-like diseases remain unknown. In recent years, high-throughput sequencing technologies have enabled us to identify many new viruses in various crops, including legumes. This review aims to present an updated list of legume-infecting viruses. Until 2020, a total of 168 plant viruses belonging to 39 genera and 16 families, officially recognized by the International Committee on Taxonomy of Viruses (ICTV), were reported to naturally infect common bean, cowpea, chickpea, faba-bean, groundnut, lentil, peas, alfalfa, clovers, and/or annual medics. Several novel legume viruses are still pending approval by ICTV. The epidemiology of many of the legume viruses are of specific interest due to their seed-transmission and their dynamic spread by insect-vectors. In this review, major aspects of legume virus epidemiology and integrated control approaches are also summarized.

“…Begomoviruses infecting legumes are grouped under legumoviruses, which mainly consist of horsegram yellow mosaic virus (HgYMV), dolichos yellow mosaic virus (DoYMV), mungbean yellow mosaic virus (MYMV), mungbean yellow mosaic India virus (MYMIV), which are known to cause yellow mosaic disease (YMD) of leguminous crop in India (Agnihotri et al, 2019). Apart from these, other viruses which are reported on legume crops are tobacco curly shoot virus (TbCSV) (Venkataravanappa et al, 2012), french bean leaf curl virus (FbLCV) (Kamaal et al, 2013), tomato leaf curl Gujarat virus (ToLCGV) (Kamaal et al, 2015) and tomato leaf curl Joydebpur virus (ToLCJV) (Ansar et al, 2019). In recent years, cultivation of pole bean in India has suffered serious losses due to yellow mosaic disease (YMD) (Archith et al, 2017).…”

The yellow mosaic disease (YMD) caused by begomoviruses is a major constraint for the production of pole bean (Phaseolus vulgaris L.) in India. Survey was carried out in the eastern dry zone of Karnataka during 2019-20 to record the incidence of yellow mosaic disease in pole bean which revealed the ubiquitous prevalence of YMD in pole bean ranging from 6.02 to 80.74 per cent. Leaf samples collected (symptomatic and asymptomatic) were subjected for begomovirus detection using specific primers. Twelve samples, representing all the 12 taluks in the surveyed region were considered for full genome amplification by RCA, cloned and sequenced. Genome length of 12 current isolates ranged from 2718 - 2744 and 2668 - 2671 nucleotides for DNA-A and DNA-B, respectively. Sequence analysis using Sequence Demarcation Tool (SDT) showed >91 per cent nucleotide identity of current isolates (DNA-A) with other horsegram yellow mosaic virus (HgYMV) isolates available in the GenBank. As per existing ICTV criteria, all the current isolates can be considered as strains of HgYMV. Further, DNA-B associated with all the 12 isolates also shared >91 per cent nucleotide identity with DNA-B of HgYMV isolates, indicating absence of component re-assortment in HgYMV. Variation in the pairwise nucleotide identity and phylogenetic analysis confirmed the existence of new strains within the current HgYMV isolates. GC plot analysis reveals potential recombination in the low GC-rich regions. Further, recombination breakpoint analysis indicated intra-species recombination in both DNA-A and DNA-B, which might have driven the origin of new strains in HgYMV. This is the first comprehensive study on begomoviruses isolates associated with the yellow mosaic disease of pole bean based on complete genome sequencing in the world.
