Despite their significance, the low natural yield of these bioactive compounds, coupled with genetic variability and environmental influences, poses significant challenges for their extraction and utilization. In recent years, plant tissue culture has emerged as a viable alternative for the controlled and consistent production of secondary metabolites. Among various strategies to boost metabolite synthesis <em>in vitro</em>, elicitation has proven to be the one of the most effective in triggering plant defense mechanisms and enhance secondary metabolite accumulation. This review comprehensively explores the role of elicitation in promoting secondary metabolite synthesis in plant cell cultures, with a particular focus on the mechanisms and regulatory functions of key elicitors like salicylic acid and methyl jasmonate. It delves into the classification of elicitors, their effects on various <em>in vitro</em> culture systems, and the potential of nanoparticles as novel elicitors. Additionally, the review discusses the co-culture technique as a promising strategy for biotechnological mining of secondary metabolites. The review also highlights the role of elicitation in improving stress tolerance in plants and emphasizes the need for continued research to overcome existing challenges and fully realize the potential of these strategies. This paper is a valuable resource for scholars and professionals in plant biotechnology, nanotechnology, and related fields, offering insights into the current state of knowledge, and future directions for enhancing secondary metabolite production in plants.</div></div>","PeriodicalId":38041,"journal":{"name":"Plant Gene","volume":"41 ","pages":"Article 100485"},"PeriodicalIF":2.2,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143176481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In plants, CNGCs are involved in cation transport, influencing growth, pathogen defense, and stress resistance. The <em>CNGC</em> gene family in <em>Brassica juncea</em> (L.) Czern (<em>BjCNGCs</em>) has not been well studied previously. We conducted a wide-ranging genome-wide analysis of <em>BjCNGCs</em> using available genomic data, covering genomic characterization, evolution, synteny analysis, gene mapping, structure, conserved motifs, cis-acting elements, potential protein association networks, post-translational modifications, and regulation. RT-qPCR assays were performed to investigate the expression patterns of selected <em>BjCNGC</em> genes in response to growth and stress. Our study identified 39 <em>BjCNGC</em> genes predicted to be present on fourteen chromosomes. Almost 49 % of these genes are positioned in conserved syntenic blocks of LF, MF-I, and MF-II sub-genomes, with a gene deletion (<em>Bra024083</em> and <em>BniB002576</em>) from the MF-I block during intraspecific hybridization. The remaining genes evolved through segmental duplications 0.22 to 0.67 million years ago under purifying selection. Phylogenetic analysis classified the BjCNGC family into four groups, with groups III and IV further subdivided into A and B. We recognized 17 miRNA target sites, six of which are involved in stress resistance, coupled with phosphorylation for regulatory control. <em>In-silico</em> methods revealed gene structures, conserved motifs, and protein interaction networks. The study identified several <em>CNGCs</em> in <em>Brassica juncea</em> (L.) Czern showed significant responses to various stresses. Remarkably, certain <em>CNGCs</em> showed increased responses to black rot and TuMV, while others were more reactive to salinity and drought conditions.

Consequently, three distinct haplotypes (Hap-1, Hap-2 and Hap-3) were identified based on the size of the intron-4 and the allelic status of the SNP in exon-5. LC-MS/MS analysis confirms that the vicine concentration varied between 3.489 and 10.025 g/kg in the entire collection of germplasm.
