Abstract Pea Fusarium wilt, incited by Fusarium oxysporum f. sp. pisi (Fop), has always been a devastating disease that causes severe yield losses and economic damage in pea-growing regions worldwide. The utilization of pea cultivars carrying resistance gene is the most efficient approach for managing this disease. In order to finely map gene, F2 population was established through cross between Shijiadacaiwan 1 (resistant) Y4 (susceptible). genetic analysis indicated Fop governed single dominant named as FwS1. Based on bulked segregant sequencing (BSA-seq) analyses, FwS1 initially detected chromosome 6 (i.e., linking group Ⅱ, chr6LG2), subsequent linkage mapping with 589 individuals fine-mapped FwS1 into 91.4 kb region. further functional annotation haplotype confirmed Psat6g003960, characterized NB-ARC (nucleotide-binding adaptor shared APAF-1, R proteins, CED-4) domain, considered promising candidate gene. encoding amino acids were altered “T/C” single-nucleotide polymorphism (SNP) first exon resulting observed differences peas. SNP locus, molecular marker A016180 determined be diagnostic validating its specificity both accessions populations different backgrounds. with KASP could facilitate marker-assisted selection breeding pea. addition, upon comparing gene Psat6g003960 74SN3B SJ1, it noted their sequences are identical, suggesting Fwf may same against wilt.

Fusarium oxysporum is one of the most economically important plant fungal pathogens, causing devastating wilt diseases on a diverse range hosts, including many key crop plants. Consequently, F. has been subject extensive research to help develop and improve protection strategies. The sequencing genome 14 years ago greatly accelerated discovery characterization genes contributing biology virulence. In this review, we summarize findings molecular mechanisms growth, reproduction, particular, focus studied through mutant analysis, covering involved in processes such as metabolism, stress tolerance, sporulation, pathogenicity, well signaling pathways that regulate them. doing so, hope present comprehensive review understanding will aid future study related species.

Pea (Pisum sativum L.) is a grain legume widely cultivated in temperate climates. It important the race for food security owing to its multipurpose low-input requirement and environmental promoting traits. key nitrogen fixation, biodiversity preservation, nutritional functions as feed. Unfortunately, like most crops, pea production constrained by several pests diseases, of which rhizosphere disease dwellers are critical due their long-term persistence soil difficulty manage. Understanding environment can improve host plant root microbial association increase yield stability facilitate improved crop performance through breeding. Thus, use various germplasm genomic resources combined with scientific collaborative efforts has contributed improving resistance/cultivation against rhizospheric diseases. This improvement been achieved robust phenotyping, genotyping, agronomic practices, resistance Nonetheless, diseases still limited, while biological chemical-based control strategies unrealistic unfavourable environment, respectively. Hence, there need consistently scout resolve these bottlenecks. Herein, view challenges, we reflect on breeding caused pathogens, including fusarium wilt, rots, nematode complex, parasitic broomrape.

Cool season legumes (Faba bean, chickpea, lentil, pea, and grass pea) are important protein harvests for food nutrition security in many countries. They play key roles sustainable cereal production through their ecological benefits. However, diseases pests attack continue to have a substantial impact on crop yield quality. Although growers used different control options manage these biotic stresses such as pesticide application, cultural practices, resistant varieties, there is pressing need the development of new, more cost-effective environmentally friendly solution help farmers facing existing environmental issues. Recently, growing interest among researchers exploiting Volatile Organic Compounds (VOCs) elaboration disease pest strategies other crops. These compounds functions relationships occurring between plants surrounding environment, well others species, pathogens. Due unique properties, VOCs can be employed improving management alternatives legume pests. In this assessment, we investigated role plant-pest plant-pathogen interactions present applications strategies. We emphasized importance employing plant farming breeding. Additionally, highlighted potential microbial facilitating microbe-microbe, microbe-plant microbe-plant-pest interactions, along with protection.
