“…The incidence of striped mosaic infection in plants in the vegetative phase is (20 -25%) which is randomly distributed in each plot, while in the generative phase ranges from (39 -47%) in each infected individual (Figure 6). Viral infections in jack beans plants have been reported in several countries including Canavalia mosaic potyvirus in Nigeria [22], Yambean mosaic virus in Brazil [23] and Bean common mosaic virus (BCMV) in Indonesia [24]. Damayanti [26] report the first information of BCMV infection in Indonesia, with characteristic mosaic that have similarities symtomps with this finding in IPPTP Muneng Probolinggo, namely light green and dark green mosaics with clear boundaries, and vein banding.…”

Jack bean (Canavalia ensiformis) is one of the potential crops in tropical areas. Arthropods, plant pests, and microorganisms were observed in Jack bean crop ecosystems. The aims of this study were to observe the presence of arthropods in Jack bean plants in dry land and dry climate area, and disease symptoms caused by microorganisms. This research was conducted at Muneng experimental station Probolinggo, using a diagonal sampling method, with yellow trap, pitfall trap, and swapping net. Symptom variation, arthropod diversity, pest attack intensity, and disease incidence were recorded. The results showed that the types of arthropods, pests, and diseases that infect and the incidence of pest and disease attack on each accession do not differ between accessions. The highest number was recorded in the sweeping net with 12 families, followed by the pitfall trap with 4 families, while in yellow traps there were 3 families. Two insects as plant pest organisms were Liriomyza sp and Maruca sp with attack rates up to 70% and 80% respectively, while jack bean diseases were wilting and mosaic with 25% and 40%. It is necessary to identify the pathogens that caused the diseases in more detail and to study the proper management of pests to reduce yield loss.

“…Earlier studies on the virus that infected Pachyrhizus erosus L. Urb. (Mexican yam bean) was thought to be a strain of BCMV but further studies later established it to be YBMV (de Sá Andrade Medeiros et al, 2019;Fuentes et al, 2012;Ha et al 2008;Damayanti et al 2008).…”

Background: Hairy senna is an edible weed grown for both its vegetables and as a hedge plant in farms and backyard gardens in Calabar. Senna hirsuta leaf samples showing virus-like symptoms were collected in the growing seasons of between 2018 and 2020 from backyard gardens and farms in Calabar and the surrounding area. Methods: The virus was isolated and transmitted by mechanical inoculation for host range studies. Seed transmissibility and transmission by aphids were further used for detection. Reverse transcription polymerase chain reaction (RT-PCR) using primers specific to the cylindrical inclusion protein gene (CI) of potyviruses followed by sequencing was used for molecular identification. The neighbour-joining phylogenetic tree was constructed to determine the relationship of the Calabar isolate with those from other parts of the world. Result: For the host range studies, four species belonging to the Fabaceae family were infected by the isolate, indicating a narrow host range. The virus was found to be seed transmissible and could be vectored by both Aphis craccivora and Aphis spiraecola. Obtained DNA fragments with the expected size of~700 bp were amplified and a pairwise comparison with other potyviruses revealed a 94-95.87% similarity with complete sequence of YBMV (JN190431). Phylogenetic analysis placed the senna isolate in the same clade as the Brazilian isolates (MK825543 and MK825544) and JN190431. On the basis of this, the virus is adjudged to be the Nigerian strain of YBMV (JN190431).

“…In India, it is cultivated in many regions of Assam, Orissa, Bihar, Tripura and West Bengal [2]. Yam bean mosaic virus was discovered for the first time in Brazil [3]. Yam bean (Pachyrrhizus erosus) is also one of the well-known legumes known as "Bengkuang" widely found in Indonesia.…”

Structural insights into the RNA interaction with Yam bean Mosaic virus (coat protein) from Pachyrhizus erosus using bioinformatics approach

Plants are constantly threatened by a virus infection, i.e., Potyviruses, the second largest genus of plant viruses which results in several million-dollar losses in various essential crops globally. Yam bean (Pachyrhizus erosus) is considered to be one of the essential tuberous legume crops holding a great potential source of starch. Yam Bean Mosaic Virus (YBMV) of Potyvirus group belonging to the family potyviridae affects Yam bean and several angiosperms both in the tropical and sub-tropical regions causing large economical losses in crops. In this study, we attempted to understand the sequence-structure relationship and mode of RNA binding mechanism in YBMV CP using in silico integrative modeling and all-atoms molecular dynamics (MD) simulations. The assembly of coat protein (CP) subunits from YBMV and the plausible mode of RNA binding were compared with the experimental structure of CP from Watermelon mosaic virus potyvirus (5ODV). The transmembrane helix region is present in the YBMV CP sequence ranging from 76 to 91 amino acids. Like the close structural-homolog, 24 CPs monomeric sub-units formed YBMV a conserved fold. Our computational study showed that ARG124, ARG155, and TYR151 orient towards the inner side of the virion, while, THR122, GLN125, SER92, ASP94 reside towards the outer side of the virion. Despite sharing very low sequence similarity with CPs from other plant viruses, the strongly conserved residues Ser, Arg, and Asp within the RNA binding pocket of YBMV CP indicate the presence of a highly conserved RNA binding site in CPs from different families. Using several bioinformatics tools and comprehensive analysis from MD simulation, our study has provided novel insights into the RNA binding mechanism in YBMV CP. Thus, we anticipate that our findings from this study will be useful for the development of new therapeutic agents against the pathogen, paving the way for researchers to better control this destructive plant virus.
