Therefore, this study was designed to explore the cosmetic potential of Helosciadium crassipes Koch (Apiaceae) species growing in Algeria as a promising natural preservative and broad-spectrum UV protection additive. In our study, the in-vitro antioxidant effect was assessed via DPPH radical scavenging and total antioxidant capacity by phosphomolybdenum method (TAC), while the protection against UVB radiation was evaluated according to the sun protection factor (SPF) by using UV spectroscopic technic at wavelengths ranging from 290 to 320 nm and Mansur’s equation, for the photoprotective effect against long-wavelength UVA, UVA/UVB and critical wavelength (λc) parameters were evaluated. The outcomes showed that among the tested extracts, the methanolic extract (MeOH) contains high levels of phenolics and flavonoids, and possesses a significant antioxidant effect, particularly in DPPH radical scavenging assay. Similarly, this last one exhibited high photoprotective activity in UVB and UVA ranges. The gathered results reveal the possibility of using this extract as a good natural additive to be incorporated into cosmetic formulations as a broad-spectrum UV protection candidate and as a preservative agent.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":"2 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139243886","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}

Worldwide, research is focused on developing new pharmaceuticals and environmentally safe materials. The current research reports the phytosynthesis of NPs from iron oxide (Fe2O3) mediated through ethanolic extracts of Andrographis serpyllifolia leaf (ASL) and their antimicrobial (bacteria and fungi) and mosquito (Culex quinquefasciatus) larvicidal activity. ASL was treated with aqueous iron chloride solution to turn into synthesized Fe2O3-NPs. The biosynthesized ASL·Fe2O3-NPs were characterized with spectroscopic, electron microscopic and X-ray analyses. The synthesized ASL·Fe2O3-NPs were characteristically showed triclinic crystal shape in SEM. The purity of synthesized Fe2O3 nanoparticles was confirmed by FT-IR analysis. Out of twelve different selective pathogens (4 G+ve bacteria, 4 G-ve bacteria and 4 fungal species) tested with ASL·Fe2O3-NPs, a maximum of 20.3 mm inhibition zone against Staphylococcus aureus among G+ve bacteria and 19.1 mm inhibition zone against Pseudomonas aeruginosa among G-ve bacteria was observed; while it was 16.9 mm against fungi (Aspergillus niger) at a test concentration of 100 µL. The exposure of 4th instar larvae for 48 h to ASL·Fe2O3-NPs exhibited a significant LC50 value at 12.80 ppm.

The data obtained were subjected to an analysis of variance, test of separation of means and a correlation analysis. The results obtained indicate that the beans analyzed are an excellent source of essential amino acids (Histidine, threonine, valine, methionine, lysine, isoleucine, leucine and phenylalanine) and non-essential amino acids (Aspartic acid, serine, glutamic acid, glycine, alanine, proline, cysteine, tyrosine and arginine). The most prominent amino acids in Mexican bean varieties were: Glutamic acid, proline, aspartic acid, serine, lysine, and leucine. Regarding antioxidant activity, the most outstanding concentrations ranged from 91.18 to 96.76% inhibition. The bean varieties with the highest accumulation of amino acids, proteins, Fe, Zn and antioxidant activity were: 1) Black-eyed (23); 2) Peruvian (154); 3) Flor de Junio (150); 4) Pinto Saltillo (155). Finally, it was found that the common bean (Phaseolus vulgaris L.) is an excellent vehicle for the biofortification of Fe and Zn, which can contribute significantly to combat malnutrition problems and health of vulnerable communities in the urban and rural sectors of Mexico, as well as in the developing countries of the world.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":"36 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139245456","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}

They can potentially be developed as horticultural and medicinal plants. Dormancy is a challenge in the cultivation of raspberries (Rubus fraxinifolius Poir.). This study was conducted as two separate experiments. The first experiment aimed to identify the dormancy mechanism of R. fraxinifolius seed. In a two-factor factorial design, the first factor was seed storage, as unstored and three-month-stored, and the second factor was chemical-immersed treatment consisting of control, H2SO4, acetone, GA3, KNO3, H2SO4-GA3, acetone-GA3, H2SO4-KNO3, acetone-KNO3. The second experiment was aimed at determining dormancy-breaking methods for R. fraxinifolius seeds. In main plots were filter paper and cocopeat germination substrates. The subplots included control, immersed with distilled water, H2SO4, ultrafine bubble water, and temperature treatment at −80 °C, 50 °C, and 70 °C. The germination of unstored and three-month-stored seeds increased after H2SO4 treatment (36 to 82% and 82 to 94%, respectively). Seed germination increased after three months of storage. There was an increase in cytokinin hormone levels along with germination enhancement. The seeds went into physical dormancy because their seed coat was hard, and they went into physiological dormancy because of low cytokinin concentration. Stratification at 50 °C increased germination (78.5 to 93.0%), reduced dormancy intensity (15 to 6.5%), and increased the percentage of the speed of germination (1.99 to 3.12 ) on filter paper substrate.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":"133 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139243111","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}

Therefore, the objectives were: a) to determine the mathematical model that best estimates normal diameter, total height, stem volume, and captured carbon as a function of stump diameter for Pinus arizonica Engelm. in northern Mexico; and b) to generate mathematical models through data processing in the Microsoft Excel program. Using a targeted sampling design, we selected 264 Pinus arizonica Engelm. trees to generate the database. The development of prediction models for normal diameter, total height, total tree volume, and captured carbon as a function of stump diameter was carried out using the Microsoft Excel database management package. The fit's adequacy was analyzed based on residuals and statistics such as the root mean square error, the adjusted coefficient of determination, and the coefficient of variation. Model fits indicate a linear trend for the normal diameter variable, while for total height, the model turned out to be logarithmic. As for total tree volume and captured carbon, the relationship is exponential in relation to stump diameter. The R2adj fits were highly reliable for estimating normal diameter, total tree volume, and captured carbon, with values exceeding 95%. The development of prediction models using Microsoft Excel is viable according to the results presented here. The tested techniques can be replicated by forestry technicians, environmental inspectors, and forest landowners who do not have specialized knowledge in the generation prediction models.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":"69 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139270771","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}

This study focused on identifying variations and relationships in the root and shoot characteristics of seven modern cultivars and twelve ancient wheat accessions of different species, including T. monococcum, T. turanicum, T. polonicum, T. mirabile, T. durum, and T. aestivum, during the early vegetative growth and stem elongation stages. The results demonstrated significant phenotypic variation among the genotypes for shoot traits, root biomass, rooting depth, R/S ratio, and seminal and nodal root numbers. When considering both growth stages, the dry land-adapted cultivar ‘Taner’ and ancient wheat species, such as T. turanicum (2) and T. monococcum (1) accessions, exhibited deeper roots, which can enhance access to water in drought-prone areas. Furthermore, it was observed that modern wheat cultivars and T. turanicum accessions exhibited increased root biomass, suggesting a higher allocation of resources towards root growth, which could potentially enhance nutrient uptake. Conversely, T. monococcum accessions and T. mirabile revealed lower root biomass compared to other ancient species and modern cultivars. Additionally, the unrooted cluster analysis based on root biomass, rooting depth, and root to shoot ratio at both growth stages indicated a distinct separation of T. monococcum accessions and T. mirabile from other genotypes. Overall, these findings underscore the importance of phenotypic diversity in root traits for crop improvement and adaptation to varying environments. Identifying genotypes with desirable root characteristics can enhance nutrient and water uptake efficiencies, leading to increased crop productivity and sustainability.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139268636","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}

The MYB transcription factor family has been identified in a variety of organisms; however, it has not been identified and analysed in the desert plant Haloxylon ammodendron. In this study, R2R3-MYB genes were identified and analysed using a bioinformatic approach. A total of 78 R2R3-MYB genes were identified and named according to their position on the chromosome. The R2R3-MYB genes were unevenly distributed on nine chromosomes. Phylogenetic analysis showed that the HaMYB genes were all divided into 31 subfamilies. Covariance analysis revealed the presence of three pairs of fragmentary duplicated genes in H. ammodendron (HaMYB54 and HaMYB17, HaMYB44 and HaMYB36, HaMYB42 and HaMYB27). Gene structure and conserved structural domain analysis revealed different subgroups with different orders of magnitude of variation in gene structures and conserved structural domains. Analysis of cis-elements showed that the cis-acting elements of HaMYBs were mainly associated with hormone and abiotic stress responses. Real-time quantitative PCR was used to detect the expression levels of HaR2R3-MYB genes, and six HaR2R3-MYB genes were found to respond to salt stress and six HaR2R3-MYB genes to drought stress, with HaMYB22 and HaMYB27 showing upregulated expression under both stresses. Transcriptome analysis showed that HaMYB63 was significantly differentially expressed in the assimilated branches of H. ammodendron, and the subcellular localization of this protein showed that it was located in the nucleus and had transcriptional self-activating activity. These results provide a theoretical basis for further studies on the functions of the R2R3-MYB gene family and the molecular mechanisms of resistance in H. ammodendron.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":"23 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139273791","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}
