Accurate estimation of State of Health (SOH) is pivotal for managing the lifecycle of lithium-ion batteries (LIBs) and ensuring safe and reliable operation in electric vehicles (EVs) and energy storage systems. While feature fusion methods show promise for battery health assessment, they often suffer from suboptimal integration strategies and limited utilization of complementary health indicators (HIs). In this study, we propose a Feature Accretion Method (FAM) that systematically integrates four carefully selected health indicators–voltage profiles, incremental capacity (IC), and polynomial coefficients derived from IC–voltage and capacity–voltage curves—via a progressive three-phase pipeline. Unlike single-indicator baselines or naïve feature concatenation methods, FAM couples’ progressive accretion with tuned ensemble learners to maximize predictive fidelity. Comprehensive validation using Gaussian Process Regression (GPR) and Random Forest (RF) on the CALCE and Oxford datasets yields state-of-the-art accuracy: on CALCE, RMSE = 0.09%, MAE = 0.07%, and R2 = 0.9999; on Oxford, RMSE = 0.33%, MAE = 0.24%, and R2 = 0.9962. These results represent significant improvements over existing feature fusion approaches, with up to 87% reduction in RMSE compared to state-of-the-art methods. These results indicate a practical pathway to deployable SOH estimation in battery management systems (BMS) for EV and energy storage applications.

We aimed to examine the effects of selenium on the tolerance of radish plants CV. Cherri Belle under cadmium phytotoxicity. The biomass accumulation was drastically decreased under Cd toxicity and the supplementary Se maintained the biomass acquisition under Cd pressure. The chlorophyll index (SPAD), PSII efficiency (Fv/Fm), and PSII quantum yield (ΦPSII) were declined in response to Cd treatment, while Se nutrition improved these variables in a dose-dependent manner. The highest H 2 O 2 and MDA contents were observed in the plants fed with 10 mg −1  L Cd. The Cd stress resulted in a considerable decline in the activities of GPX, CAT, and APX antioxidant enzymes, while Se supplementation increased their activities in the Cd-treated plants. Based on the mineral analyses, no Cd was traced in the control plants, while the Cd concentration in both roots and leaves of the Cd-stressed radish plants increased with increasing the supplemented Cd levels. Compared with plants solely treated with 10 mg L −1 Cd, Se nutrition declined the Cd absorption in roots and in leaves. The concentration of evaluated micronutrients including Fe, Mn, Cu, and Zn tended to decrease in the Cd-imposed plants in comparison with control plants. Se nutrition of both stressed and non-stressed radish plants increased the concentrations of the studied microelements, except for Zn in which the individual use of Se led to a decrease in the Zn content. Significant positive and negative correlation values were found among the studied traits and the principle component analysis (PCA) biplot and Ward dendrogram confirmed the results of the correlation analysis. Se proved to be efficient in the alleviation of Cd-triggered deleterious effects by improving biomass acquisition, enhancing chlorophyll biosynthesis and fluorescence, and increasing micronutrient uptake in a dose-dependent manner. Furthermore, the Se alleviation mechanism under Cd stress was also connected with the activation of enzymatic antioxidative protection system as well as with decreasing Cd uptake, transport, and distribution in radish leaves. Altogether, our research strongly suggests the implementation of Se in the growth medium to enhance the tolerance of radish plants under Cd stress.

Background Mentha longifolia L. is a perennial plant belonging to the Lamiaceae family that has a wide distribution in the world. M. longifolia has many applications in the food and pharmaceutical industries due to its terpenoid and phenolic compounds. The phytochemical profile and biological activity of plants are affected by their genetics and habitat conditions. In the present study, the content, constituents and antifungal activity of the essential oil extracted from 20 accessions of M. longifolia collected from different regions of Iran and Iraq countries were evaluated. Results The essential oil content of the accessions varied between 1.54 ± 0.09% (in the Divandarreh accession) to 5.49 ± 0.12% (in the Khabat accession). Twenty-seven compounds were identified in the essential oils of the studied accessions, which accounted for 85.5-99.61% of the essential oil. The type and amount of dominant compounds in the essential oil were different depending on the accession. Cluster analysis of accessions based on essential oil compounds grouped them into three clusters. The first cluster included Baziyan, Boukan, Sarouchavah, Taghtagh, Darbandikhan, Isiveh and Harir. The second cluster included Khabat, Kounamasi, Soni and Mahabad, and other accessions were included in the third cluster. Significant correlations were observed between the essential oil content and components with the climatic and soil conditions of the habitats. The M. longifolia essential oil indicated antifungal activity against Fusarium solani in both methods used. In all studied accessions, the fumigation method compared to the contact method was more able to control mycelia growth. In both methods, the inhibition percentage of essential oil on mycelia growth increased with an increase in essential oil concentration. Significant correlations were found between the essential oil components and the inhibition percentage of mycelium growth. Conclusion The studied M. longifolia accessions showed significant differences in terms of the essential oil content and components. Differences in phytochemical profile of accessions can be due to their genetic or habitat conditions. The distance of the accessions in the cluster was not in accordance with their geographical distance, which indicates the more important role of genetic factors compared to habitat conditions in separating accessions. The antifungal activity of essential oils was strongly influenced by the essential oil quality and concentration, as well as the application method. Determining and introducing the elite accession in this study can be different depending on the breeder’s aims, such as essential oil content, desired chemical composition, or antifungal activity.

Fennel (Foeniculum vulgare Mill) is a valuable medicinal plant from the Apiaceae family, cultivated for its essential oil, seeds, and leaves, which are used in the pharmaceutical, food, and cosmetics industries. This study tested the hypothesis that plant growth regulators (PGRs) positively modulate the morphological, physiological, and phytochemical properties of fennel. To test this hypothesis, a factorial experiment was carried out with foliar applications of four plant growth regulators, including salicylic acid (SA: 1 and 2 mM), gibberellic acid (GA: 0.25 and 0.5 mM), gamma-aminobutyric acid (GABA: 5 and 10 mM), and sodium nitroprusside (SNP: 1.25 and 2.5 mM). The results showed that SNP2.5 and GA0.5 treatments achieved the greatest improvement in growth and morphological traits. For the SNP2.5 treatment, morphological traits exhibited percentage changes ranging from 36.5 to 198.6%. SNP2.5 and SA2 treatments resulted in the highest values for physiological traits. The SNP2.5 treatment caused significant increases in flavonoid and phenolic contents, DPPH radical scavenging activity, and chlorophyll and carotenoid levels, with increases ranging from about 39% to 231% compared to the control. Meanwhile, SA (1 and 2 mM) and GA0.25 had superior effects on phytochemical traits, including essential oil yield and secondary metabolites. GABA10 also positively influenced all traits, though to a lesser extent than other treatments. Control plants consistently exhibited the lowest values across all traits. Metabolite analysis using GC-MS identified a total of 150 compounds, among which 41 showed significant differences among treatments. Notably, six major metabolites accounted for about 70% of the total metabolite content, including apiol (0.742–1.299), camphene hydrate (0.407–0.708), cis-anethole (0.328–0.975), estragole (0.916–1.059), phenyl acetate (5.005–9.705), and limonene (3.902–1.647) respectively for SA1 and SA2. Among these, cis-anethole (40–75%) and limonene (6.5–19%) were identified as the predominant components in the essential oil of the leaves. These findings suggest that certain plant growth regulators, especially SNP and SA, can be used as effective agricultural tools for improving the growth and phytochemical quality of fennel.

Melon ( Cucumis melo L.) is an essential dietary component in Iran and Iraq, making the understanding of its genetic diversity crucial for breeding and conservation efforts. However, limited studies have investigated the genetic diversity of melon populations in these regions. This study evaluated the genetic diversity and population structure of 80 melon genotypes collected from 20 regions across Iran and Iraq using Inter-Simple Sequence Repeat (ISSR) and Start Codon Targeted (SCoT) markers. A total of 11 ISSR and 14 SCoT primers generated 166 and 245 fragments, respectively. The mean percentage of polymorphism was higher for ISSR (77.67%) than SCoT (68.47%). However, SCoT markers exhibited a higher polymorphic information content (0.438) compared to ISSR markers (0.374), indicating superior discriminatory power. The resolving power of the primers was comparable between the two marker systems. Cluster analysis using the Jaccard similarity coefficient and UPGMA algorithm grouped the genotypes into two and four clusters based on ISSR and SCoT markers, respectively, a pattern further supported by principal component analysis. Analysis of molecular variance revealed greater intra-population variation than inter-population variation for both markers. A combined marker analysis classified the genotypes into three major groups. Overall, our findings indicate that SCoT markers are more effective than ISSR markers for assessing genetic diversity and population structure in melon genotypes. This study provides valuable insights for melon breeding and conservation programs in Iran and Iraq.

Plastid transformation is a powerful tool for basic research, but also for the generation of stable genetically engineered plants producing recombinant proteins at high levels or for metabolic engineering purposes. However, due to the genetic makeup of plastids and the distinct features of the transformation process, vector design, and the use of specific genetic elements, a large set of basic transformation vectors is required, making cloning a tedious and time-consuming effort. Here, we describe the adoption of standardized modular cloning (GoldenBraid) to the design and assembly of the full spectrum of plastid transformation vectors. The modular design of genetic elements allows straightforward and time-efficient build-up of transcriptional units as well as construction of vectors targeting any homologous recombination site of choice. In a three-level assembly process, we established a vector fostering gene expression and formation of griffithsin, a potential viral entry inhibitor and HIV prophylactic, in the plastids of tobacco. Successful transformation as well as transcript and protein production could be shown. In concert with the aforesaid endeavor, a set of modules facilitating plastid transformation was generated, thus augmenting the GoldenBraid toolbox. In short, the work presented in this study enables efficient application of synthetic biology methods to plastid transformation in plants.

Himantoglossum affine is a threatened terrestrial orchid. We aimed to optimize asymbiotic seed germination and direct embryogenesis and to analyze the phytochemical profile and physico-biochemical analysis of leaf and tuber. The individual use of organic nitrogen compounds resulted in higher germination efficiencies, while the shortest times to germination were observed using coconut water plus casein hydrolysate. Plantlets grown on media supplemented with pineapple juice and peptone had the highest plantlet length and weight. For embryogenesis, the highest regeneration rate (44%) and embryo number/explant (10.12 ± 2.08) were observed in young protocorm-like body (PLB) explants with 0.5 mg/L naphthalene acetic acid (NAA) and 1 mg/L thidiazuron (TDZ). During the acclimatization process, the scattered vascular tubes converted to fully developed vascular tissues, ensuring maximum sap flux. Gas chromatography–mass spectrometry analysis identified 1,2,3-propanetriol, monoacetate, 4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl, and 2-butenedioic acid, 2-methyl-, (E)- as the most prevalent compounds. We reported higher contents of total phenolics and flavonoids and antioxidant activity compared to other terrestrial orchids. The glucomannan content (36.96%) was also higher than starch content (31.31%), comparable to those reported in other tuberous orchids. Based on the fragmentation of H. affine populations in the Middle East and Euro-Mediterranean countries due to over-harvesting, climate change, and/or human impact, our procedure offers a tool for the re-introduction of in vitro-raised plants to threatened areas.

Phospholipases are among the important elements involved in lipid-dependent cell signaling that lead to the induction of downstream pathways. In the current study, phospholipases D (PLDs) gene family was characterized and compared in two important oilseed crops, Brassica napus and Camelina sativa. The results revealed that PLD has 33 members in Camelina sativa (CsPLD) and 41 members in Brassica napus (BnPLD). All studied PLDs showed a negative GRAVY value, indicating that PLDs are probably hydrophilic proteins. Phylogenetic analysis classified PLDs into five main subfamilies, including gamma, delta, beta, alpha, and zeta. According to evolution analysis, a different evolution process was observed between CsPLD and BnPLD. In addition, the results disclosed that most of the PLD genes have been segmentally duplicated under purifying selection. Cis-regulatory elements related to ABA and auxin responsiveness were found more in the upstream region of CsPLDs, while elements linked with MeJA responsiveness were observed more in the promoter region of BnPLDs. Analysis of the expression data showed that PLD alpha genes have a wide expression in most tissues. Quantitative expression analysis (qPCR) of CsPLD genes under salt stress, 200 mM of NaCl, was conducted in different time series. The results revealed that the CsPLD genes are involved in the response to salinity stress and their expression levels enhance with increasing salinity stress period. The outcomes of this research will be useful for future molecular works related to lipid signaling in oilseed plants.

We aimed to evaluate the possibility the nuclear transformation of lettuce and tobacco to produce recombinant anti-HIV microbicide griffithsin under impact of Zera signal peptide. For this purpose, the codon optimized GRFT fused with KDEL retention signal was used with and without the Zera (γ-zein ER-accumulating domain) signal peptide. Integration of GRFT into the nuclear genome of lettuce and tobacco transgenic lines was confirmed by polymerase chain reaction (PCR) and Southern blot analysis. Subsequent reverse transcription-quantitative PCR (RT-qPCR) experiments showed highly divergent GRFT expression patterns, inherent to the applied transformation procedure. The recombinant GRFT was successfully detected by means of western blot and quantified by ELIZA. According to ELIZA results, fusion of GRFT with Zera signal peptide resulted in higher accumulation of the recombinant protein in both species once compared with transgenic line without signal peptide. Lettuce showed higher transgene transcripts and accumulated more the recombinant protein of interest (up to 8.942 µg/100 mg) than tobacco. Both lettuce- and tobacco-derived GRFT (GRFTL and GRFTT, respectively) captured gp120 in a way comparable to E. coli expressed GRFT (GRFTE). Our results suggest that lettuce as a leafy vegetable crop and tobacco as a model plant in transgenic research studies can be used as suitable candidate hosts for the production of recombinant GRFT, augmented by recruitment of plant optimized codon compositions and suitable signal peptide.
