However, its cultivation faces significant challenges from pests, diseases, and environmental stresses. Among these, Fusarium wilt (FW) caused by pathogen Fusarium oxysporum f. sp. pisi poses a severe threat, resulting in substantial yield losses globally. Four pathogenic races (1, 2, 5, and 6) of this fungus have been primarily identified, and its broad host range further complicates effective management. Traditional control methods including cultural practices, physical control, biological interventions, and chemical treatments have shown limited efficacy. Consequently, host-plant resistance has emerged as a sustainable and practical solution for managing FW. In this review, the advancements in genetics with modern molecular techniques such as SNP genotyping, QTL mapping, and marker-assisted selection for the development of FW resistant pea varieties were highlighted. Furthermore, we also discussed the omics techniques viz., transcriptomics, metabolomics and proteomics and innovative breeding techniques like CRISPR-mediated genome editing, speed breeding, and genomic selection for revolutionize FW resistance breeding programs in pea. Therefore, this review focuses on integrating cutting-edge molecular techniques with omics approaches to unravel Fusarium wilt defense mechanisms in garden pea, aiming to accelerate genetic gains and develop superior disease-resistant varieties for improved productivity and quality.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 4","pages":"89"},"PeriodicalIF":3.8,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144691203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its cultivation is constrained by several abiotic stresses, notably sodicity, which significantly reduces productivity and is expected to worsen in the near future. In this study, a genome-wide association study (GWAS) was conducted to identify genomic regions and candidate genes associated with sodicity tolerance in rice. A rice association mapping panel consisting of 150 genotypes was evaluated for sodicity tolerance traits across four environments and genome-wide single nucleotide polymorphisms (SNPs) obtained using genotyping-by-sequencing (GBS) approach. The results revealed high phenotypic variation and heritability for six sodicity tolerance traits across the evaluated environments. The high-quality SNPs obtained were subjected to linkage disequilibrium (LD) block construction, resulting in 5,459 tag-SNPs, which were used for population structure and GWAS analyses. Population structure analysis revealed nine distinct sub-populations (k = 9) within the panel. GWAS, using three multi-locus models, identified 27 consistent and stable marker-trait associations (MTAs) for six sodicity tolerance traits across 10 chromosomes. A candidate gene search within the corresponding LD block regions identified 57 putative candidate genes associated with sodicity tolerance. Furthermore, gene-based haplotype analysis was conducted for these candidates and revealed that four genes-encoding ADP-glucose pyrophosphorylase, phenolics efflux transporter, DUF1296 family proteins, and F-box domain-containing proteins-exhibited significant differences among their haplotype groups.

Mutating any one of 18 of these amino acid residues to alanine, thereby removing their side chains, abolished or impaired CESA function, with the strongest effects observed upon the loss of charged amino acid side chains.
