“…The serological test result showed that CpCSV and PSbMV were widely distributed in the surveyed areas. The present study agrees with previous reports that these two viruses remain to be economically important on legume crops in Ethiopia (Abraham et al, 2006;Abraham & Vetten, 2022;Bekele et al, 2005;Tadesse et al, 1999) and provides additional evidence confirming the role of biophysical factors on the distribution of these viruses. Results obtained are in line with the earlier findings, and it showed that CpCSV had become the most predominantly distributed virus compared to other identified viral diseases.…”

“…Insect pests such as aphids, cutworms, pod borers, thrips and seed weevils are known to cause economic damage in lentil and chickpea crops in the field and storage (Ujagir & Byrne, 2009). Similarly, foliar diseases like rust, wilt/root rot complex, Ascochyta blights and viruses are known to affect the productivity of lentil and chickpea crops (Abraham & Vetten, 2022; Ahmed & Melkamu, 2006; Tadesse et al., 2008, 2012). Parasitic weeds are also big problem in the northern highlands of Ethiopia (Negewo et al., 2022; Tadesse et al., 2018).…”

Food legumes are key commodities produced in sole and mixed cropping system in Ethiopia. Their productivity has been affected recently by virus infections. Field surveys were conducted from 2018/19 to 2021/22 cropping seasons in the highlands of Ethiopia to identify major viruses and determine how biophysical factors affect disease incidence. A total of 2797 samples of chickpea (755), lentil (1683), fenugreek (111) and grass pea (248) were collected from 194 farmers' fields in Amhara (North Shewa, South Wollo and East Gojjam zones) and Oromia (East Shewa, West Shewa and North Shewa zones) regions. Laboratory testing using Tissue blot immunoassay showed that chickpea chlorotic stunt virus (CpCSV, genus Polerovirus, family Solemoviridae) and pea seed‐borne mosaic virus (PSbMV, genus Potyvirus, family Potyviridae) were the major viruses affecting legume crops in Ethiopia. The highest relative virus incidence of CpCSV (90.6%) and PSbMV (11.5%) was recorded in samples of chickpea and lentil crops, respectively. Except for crop conditions, all the independent variables significantly affected PSbMV incidence, whereas all independent variables showed a highly significant association (p < .0001) with CpCSV Incidence. A CpCSV incidence of ≥30% had a high probability of association with chickpea and fenugreek crops, the presence of aphid vectors and the 2018/19 cropping season. Similarly, PSbMV with an incidence ≥7% was highly associated with the 2018/19 cropping season. Both viruses can be managed by the combined application of cultural practices, insecticide's application, healthy seeds and resistance breeding.

“…It is an emerging concern, posing a serious challenge to chickpea production and causes up to 95% yield loss ( Abraham and Vetten, 2022 ). Interestingly, two different pathogens, viz ., Chickpea chlorotic stunt virus (CpCSV), a member of Polerovirus ( Abraham and Vetten, 2022 ) and Chickpea chlorotic dwarf virus (CpCDV), a member of Mastrevirus , family Geminiviridae ( Kanakala and Kuria, 2018 ) are found to be associated with this disease. Small leaves, discolotration and bushy stunted appearance are the major symptoms of this disease.…”

Major viral diseases in grain legumes: designing disease resistant legumes from plant breeding and OMICS integration

Grain legumes play a crucial role in human nutrition and as a staple crop for low-income farmers in developing and underdeveloped nations, contributing to overall food security and agroecosystem services. Viral diseases are major biotic stresses that severely challenge global grain legume production. In this review, we discuss how exploring naturally resistant grain legume genotypes within germplasm, landraces, and crop wild relatives could be used as promising, economically viable, and eco-environmentally friendly solution to reduce yield losses. Studies based on Mendelian and classical genetics have enhanced our understanding of key genetic determinants that govern resistance to various viral diseases in grain legumes. Recent advances in molecular marker technology and genomic resources have enabled us to identify genomic regions controlling viral disease resistance in various grain legumes using techniques such as QTL mapping, genome-wide association studies, whole-genome resequencing, pangenome and ‘omics’ approaches. These comprehensive genomic resources have expedited the adoption of genomics-assisted breeding for developing virus-resistant grain legumes. Concurrently, progress in functional genomics, especially transcriptomics, has helped unravel underlying candidate gene(s) and their roles in viral disease resistance in legumes. This review also examines the progress in genetic engineering-based strategies, including RNA interference, and the potential of synthetic biology techniques, such as synthetic promoters and synthetic transcription factors, for creating viral-resistant grain legumes. It also elaborates on the prospects and limitations of cutting-edge breeding technologies and emerging biotechnological tools (e.g., genomic selection, rapid generation advances, and CRISPR/Cas9-based genome editing tool) in developing virus-disease-resistant grain legumes to ensure global food security.
