Traditional plumbagin extraction, involving root uprooting and plant destruction, raises ecological concerns. The primary objective of this study is to enhance plumbagin production by incorporating the elicitation process into in vitro cultivation with regenerated plants that retain all of their intact organs. Seven different elicitors categorized into three distinct groups were employed to stimulate plumbagin content. Among the various elicitors used, this study marks the first application of biogenic silver nanoparticles (AgNPs) from <em>Curcuma amada</em> in stimulating plumbagin production in this plant. The maximum plumbagin content, recorded at 8.98 ± 0.24 mg/g dry weight basis, was found in the roots when elicited with AgNPs at a concentration of 15 mg/l. In addition to that, biotic elicitors (yeast extract, chitosan and casein hydrolysate) and heavy metals (lead, cobalt and nickel) also successfully elicit plumbagin in the root and aerial parts of the plants, quantified through High Performance Liquid Chromatography (HPLC). In our study, we found that certain elicitors induced root browning and tissue necrosis, as confirmed by propidium iodide (PI) staining. The most significant browning effects were observed with chitosan from biotic sources and lead from heavy metals, while no such effects were associated with AgNPs at any concentration. Utilizing intact, entire plants as the subjects for elicitation in our study is a valuable aspect. This approach closely replicates the natural process occurring in intact plants, enhancing the relevance of our findings to practical situations.</p>","PeriodicalId":20219,"journal":{"name":"Plant Cell, Tissue and Organ Culture","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140562031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basal salt, sucrose and Benzyaminopurine (BAP) concentrations were derived from Box-Behnken design of RSM. The response surface regression analysis revealed that 1.0 g/L MS + 0.1 mg/L BAP + 25 g/L sucrose was optimized for maximum regeneration (100%), shoot counts (63.2), and fresh weight (1.382 g). The RSM-based predicted scores were fairly similar to the actual scores, which were 100% regeneration, 63.39 shoot counts, and 1.44 g fresh weight. Pareto charts analysis illustrated the significance of MS for regeneration and fresh weight but remained insignificant. Conversely, MS × BAP was found to be the most crucial factor for the shoot counts, with MS coming in second and having a major influence. The analysis of the normal plot ascertained the negative impact of elevated MS concentration on shoot counts and enhanced shoot counts from the combination of MS × BAP. Results were further optimized by constructing contour and surface plots. The response optimizer tool demonstrated that maximum shoot counts of 63.26 and 1.454 g fresh weight can be taken from the combination of 1.0 g/L MS + 0.114 mg/L BAP + 23.94 g/L. Using three distinct performance criterias, the results of machine learning models showed that the multilayer perceptron (MLP) model performed better than the random forest (RF) model. Our findings suggest that the results may be utilized to optimize various input variables using RSM and verified via ML models.</p><h3 data-test=\"abstract-sub-heading\">Key message</h3><ul>\u0000<li>\u0000<p>Optimization of in vitro whole plant regeneration of Brazilian sword wood using response surface methodology</p>\u0000</li>\u0000<li>\u0000<p>Data analysis through ANOVA, response surface regression anlaysis and machine learning</p>\u0000</li>\u0000<li>\u0000<p>Graphical presentation of data via Pareto charts, normal plots, contour plots and surface plots for optimization</p>\u0000</li>\u0000<li>\u0000<p>Better performance of ANN-based MLP model compared to decision tree based RF model</p>\u0000</li>\u0000</ul><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":20219,"journal":{"name":"Plant Cell, Tissue and Organ Culture","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140561892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Propagation of <i>M. azedarach</i> through conventional methods is difficult and azadirachtin production low, therefore in vitro tissue culture can constitute an effective alternative for stable, continuous and high-yield secondary metabolites production. For this purpose, in the present study, the effects of explant type (leaves, immature flowers), plant growth regulators [2,4-D or TDZ (0, 1, 2 mg/L), 2,4-D + TDZ (1 + 1, 1 + 2, 2 + 1, 2 + 2 mg/L)], UV-B radiation exposure time (0, 1, 2, 3, 4 h/day), and incubation period (2, 4 weeks) on producing azadirachtin and growth parameters (fresh weight, dry weight, growth index %) in vitro callus culture of <i>M. azedarach</i> were assessed. Results showed that leaf explants gave superior percentage for callus induction (100%) (4 weeks) and fresh weight (54.77 mg) (8 weeks) compared with immature flower explants (96.67%, 51.20 mg) under 2 mg/L 2,4-D + 2 mg/L TDZ. Leaf-derived calli exhibited significantly higher growth parameters and azadirachtin content than immature flower-derived calli under the same UV-B exposure time and incubation period in MS medium under 2 mg/L 2,4-D + 2 mg/L TDZ. The maximum increase in azadirachtin and growth parameters was achieved in leaf-derived callus by the highest UV-B exposure time of 4 h/day and the longest incubation period of 4 weeks (fresh weight: 1139.95 mg, dry weight: 115.35 mg, growth index: 279.98%, azadirachtin: 14.93 mg/g dry weight). The process of callus culture in association with UV-B irradiation as an elicitor can be a viable option for the production of azadirachtin in a large-scale bioreactor fulfilling the ever escalating industrial demand for plant-derived extracts.

The results revealed that the maturation temperature did not affect the morphology of the resulting somatic plantlets, nor the ploidy and genome size of phenotypically normal somatic embryos, whose ploidy and DNA content levels were similar to those found in mature zygotic embryos. Nonetheless, a slight but significant reduction of the genome size of aberrant somatic embryos was observed. The maturation temperature changed the levels of glycine, arginine, lysine, and ornithine. These last three amino acids are precursors of the polyamines detected. Regarding this, putrescine levels were higher in somatic embryos from the highest maturation temperature (5 min pulse at 60 ºC), however, the amount of this polyamine in all samples was much lower than spermidine, spermine and cadaverine. In conclusion, the different temperatures applied did not lead to substantial changes in the ploidy level, endogenous PAs of the somatic embryos developed, or in the morphology of the somatic plantlets.
