Legumes are primarily grown agriculturally for human consumption, livestock forage, silage, and as green manure. However, production has declined primarily due to fungal pathogens. Among them, this study focused on Fusarium spp. that cause Fusarium wilt in minor legumes in Korea. Diseased legume plants were collected from 2020 to 2021, and diverse fungal genera were isolated from the internal tissues of the plant roots and stems. Fusarium spp. were the most dominant, accounting for 71% of the isolates. They were identified via morphological characteristics and molecular identification. In the pathogenicity test, Fusarium oxysporum and Fusarium fujikuroi generally exhibited high virulence. The host range investigation revealed that the NC20-738, NC20-739, and NC21-950 isolates infected all nine crops, demonstrating the widest host range. In previous studies, the focus was solely on Fusarium wilt disease in soybeans. Therefore, in this study, we aimed to investigate Fusarium wilt occurred in minor legumes, which are consumed as extensively as soybeans, due to the scarcity of data on the diversity and characteristics of Fusarium spp. existing in Korea. The diverse information obtained in this study will serve as a foundation for implementing effective management strategies against Fusarium-induced plant diseases.

“…Biotic stress: When living things, such as weeds, insect pests, disease-causing agents, nematodes, allelopathic compound and pathogen harm plants it results in biotic stress. During various phases of plant growth, fungi and viruses are most prevalent and significant groupings affecting all areas of the plant (Mahmoud, 2021;Pande et al, 2006). Chickpea diseases: Fungal diseases, followed by viral and bacterial illnesses, are the most important disease that contribute to a general decrease in the annual yield of chickpeas.…”

The third-most important food legume in terms of economic importance worldwide is the chickpea (Cicer arietinum L.). Its potential production is frequently constrained by numerous biotic stressors, such as the nematodes, insects Ascochyta blight, fusarsium wilt, and botrytis grey mould are the three major fungal diseases that cause significant economic losses, while Helicoverpa armigera, Aphis craccivora, cowpea weevil are the three major pre-harvest pest of chickpea. Several biological, chemical, cultural and, agronomical practices are used to control biotic stress, apart from that few modern biotechnological approaches also developed for high yielding and biotic stress resistant varieties. This paper aims to elaborate about different biotic stresses that affect Chickpea plant, their management strategies including traditional chemicals and adaptation of transgenic varieties with their limitations and also enlightened newer ray of hope i.e., plant growth promoting rhizobacteria that holds the ability to combat against biotic stress by mitigating stress ethylene level.

“…ciceris), wet root rot (Rhizoctonia solani), vascular wilt (F. oxysporum f. sp. lentis) are contributed to major yield loss in legumes crops as compared to all others (Sampaio et al, 2020;Mahmoud, 2021;Pandey and Basandrai, 2021;Urva, 2021). Nematodes (Cyst and root-knot) are also a major factor of yield loss in legumes (Zwart et al, 2019).…”

The world is facing rapid climate change and a fast-growing global population. It is believed that the world population will be 9.7 billion in 2050. However, recent agriculture production is not enough to feed the current population of 7.9 billion people, which is causing a huge hunger problem. Therefore, feeding the 9.7 billion population in 2050 will be a huge target. Climate change is becoming a huge threat to global agricultural production, and it is expected to become the worst threat to it in the upcoming years. Keeping this in view, it is very important to breed climate-resilient plants. Legumes are considered an important pillar of the agriculture production system and a great source of high-quality protein, minerals, and vitamins. During the last two decades, advancements in OMICs technology revolutionized plant breeding and emerged as a crop-saving tool in wake of the climate change. Various OMICs approaches like Next-Generation sequencing (NGS), Transcriptomics, Proteomics, and Metabolomics have been used in legumes under abiotic stresses. The scientific community successfully utilized these platforms and investigated the Quantitative Trait Loci (QTL), linked markers through genome-wide association studies, and developed KASP markers that can be helpful for the marker-assisted breeding of legumes. Gene-editing techniques have been successfully proven for soybean, cowpea, chickpea, and model legumes such as Medicago truncatula and Lotus japonicus. A number of efforts have been made to perform gene editing in legumes. Moreover, the scientific community did a great job of identifying various genes involved in the metabolic pathways and utilizing the resulted information in the development of climate-resilient legume cultivars at a rapid pace. Keeping in view, this review highlights the contribution of OMICs approaches to abiotic stresses in legumes. We envisage that the presented information will be helpful for the scientific community to develop climate-resilient legume cultivars.
