Greater attention should be given to the existing data on its chorology and habitat preferences in the country. Some pertinent records are dispersed in various local literature sources and herbaria. In Slovakia, this alien species was recorded for the first time in 1924, but the significant increase in localities started after 1980. G. sibiricum has been found in 67 localities scattered irregularly throughout the Pannonian and Carpathian phytogeographical regions. It has been noted in a wide range of anthropogenic habitats at low to middle elevations. Recently, it has spread mainly in urban areas in eastern Slovakia and along railway tracks in northern and western Slovakia.","PeriodicalId":9161,"journal":{"name":"Botanica Serbica","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135610236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current experiment was carried out to investigate the proteome changes in frost-tolerant winter wheat (cv. Norstar) during different cold acclimation (CA) periods under field conditions in a cold and high-altitude region by two-dimensional gel-based proteomic techniques. The results showed that frost tolerance significantly increased by CA and the lethal freezing temperatures (LT50) 10, 14, and 18 weeks after seed sowing were -28?C, -22?C, and -10?C, respectively. By the beginning of the reproductive stage (double ridge stage), the LT50 values had decreased significantly. Around 1000 protein spots were distinguished by Coomassie staining on the gels. The changes in the proteins during the CA often occurred in those with a functional role in photosynthesis, energy production (glycolysis), transcription, chaperone-like activities, membrane and cytoskeleton reorganisation, transport, redox adjustments, and signalling. The results revealed that changes in chloroplast proteins, certain transcription factors such as MADS-box transcription factor 26, and antioxidant enzymes (ascorbate peroxidase) show a similar trend to freezing tolerance, and their expression decreases with the onset of reproductive growth and the loss of freezing tolerance. During the acclimation period, most of the changes were focused on defence systems and cytoskeleton rearrangement, while, photosynthesis, and energy production became the main priority at the beginning of reproductive growth.","PeriodicalId":9161,"journal":{"name":"Botanica Serbica","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135610474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chlorogenic acid was the most represented among the 10 detected phenolic compounds. As inferred by the sugar content, sucrose, fructose and glucose were the most dominant sugars, but it is worth mentioning the abundance of trehalose and turanose at least during one of the observed seasons. The presence of four trisaccharides and one tetrasaccharide within P. formosum should be highlighted, as well as the first reports of turanose, isomaltotriose, panose and rhamnose within this species. The quantitative changes over the year clearly demonstrate carbohydrate dynamics in relation to seasonal climatic variation. Sugars are shown to be significant constitutive molecules within P. formosum, but also physiologically active compounds, i.e. signalling and energy storage and supplier molecules.

After 8 weeks, the highest level of growth and densest hyphal branching were recorded in the medium containing glucose as the main carbohydrate. For nitrogen, glutamine (200 mg N l-1) provided the greatest hyphal growth and density compared to the other amino acid treatments. Regarding temperature, 16?C proved to be optimal for T. brumale growth and branching. Media of pH 6 and pH 7 were most favourable for the growth of T. brumale.

To address these deleterious effects, plants activate various non-enzymatic and enzymatic antioxidants. This study seeks to detect the influence of seasonal variation in Hedera helix (ivy) leaves, collected in Banj brdo (Banja Luka, Republika Srpska, Bosnia and Herzegovina) between December 2017 and November 2018, on oxidative (hydrogen peroxide and malondialdehyde) and antioxidant (superoxide dismutase, catalase, Class III peroxidases, and phenolic compounds) parameters. During the winter-early spring months (a temperature range of 0.7 to 5.4?C), we detected an increase in the values of all the oxidative and antioxidant parameters, whereas during the spring, summer, and autumn months (a temperature range of 15 to 25?C), the values of most of these parameters fell. However, a peak in the parameter values was detected during June and July 2018, which might be attributable to the influence of the changes in both light intensity and temperature and to the effects of intensive shoot growth. Our results highlight the importance of the antioxidant protection system of H. helix for its acclimation to seasonal variations in the environment, especially temperature.","PeriodicalId":9161,"journal":{"name":"Botanica Serbica","volume":"11 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79139706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In submerged aquatic plants, N and P resorption efficiencies (REN, REP) from senescing leaves or shoots are high (usually >40% in dry weight, DW), but K resorption efficiency (REK) is usually very low or zero. The free-floating aquatic fern Salvinia natans has a linear, modular shoot structure exhibiting steep growth and a physiological polarity, and consists of oval, floating, natant leaves with photosynthetic functions and thread-like submerged leaves which absorb nutrients. To obtain the basic mineral nutrient characteristics, REN, REP and REK were estimated in the senescent floating and submerged leaves of this species grown in an outdoor culture. The N content in all the leaves was in the range between 1.10-1.42% DW, P 0.33-0.57% DW and K between 4.03-6.20% DW, indicating a partial N growth limitation but a liberal P uptake. Contrary to expectations, the REN values in both types of leaves were relatively low (7-31%), those of REP even negative (-7 to -12%), while the REK values were relatively high (31-44%). These results are in contrast to much higher N and P resorption efficiencies reported in both submerged plants and the similar tropical species S. molesta. The REK values found in S. natans are in accordance with those reported in S. molesta, but are much higher than those in submerged plants. Thus, the submerged leaves (rhizophylls) of the Salvinia species do not behave in the same way as the leaves of higher submerged plants in terms of the K economy.","PeriodicalId":9161,"journal":{"name":"Botanica Serbica","volume":"45 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81448730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concentration of the total phenols and flavonoids, as well as the antioxidant activity of the stalk extracts were measured by means of the spectrophotometric method. In vitro antimicrobial activity of 23 selected species of microorganisms (13 species of bacteria and 10 species of fungi) was evaluated by determining the minimum inhibitory concentration (MIC) and the minimum microbicidal concentration (MMC). The results indicated that the highest concentration of total phenols was measured in the ethyl acetate extract (60.08 mg GAE/g of extract), while the highest total flavonoid concentration was observed in the acetone extract (34.24 mg RUE/g of extract). The tested extracts showed poor antioxidant activity compared to chlorogenic acid. The acetone extract probably showed the strongest antimicrobial activity due to the high concentrations of phenols and flavonoids. The tested extracts showed a better effect on Gram-positive bacteria than on Gram-negative bacteria.

The antioxidant activity of the plant was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-Azinobis-(3-Ethylbenzthiazolin-6-Sulfonic Acid) (ABTS), iron chelating capacity, and a ?-carotene / linoleic acid emulsion assay. The total phenol and flavonoid contents of the plant were determined using the Folin-Ciocalteu and aluminum chloride methods, respectively. The study of the enzyme inhibition activity of the plant was carried out for acetylcholinesterase, butyrylcholinesterase, ?-glucosidase, ?-amylase, and tyrosinase. The antiglycation activity of the aqueous extract of the plant was evaluated using established methods such as browning, a Nitroblue-tetrazolium (NBT) assay, the 2,4-dinitrophenyl hydrazine (DNPH) method, a Congo red assay, and fluorescent Bovine Serum Albumin (BSA). The HPLC profiling of the phenolics revealed that 18 standard phenolic compounds were found in different amounts in various extracts of the plant parts. According to our bioactivity results, the methanol extract obtained from the flower parts of the plant contained higher amounts of phenolic compounds and flavonoids, which also demonstrated the highest DPPH radical scavenging activity. In addition, the methanol extracts obtained from the leaves and roots were found to be the most active extracts against the acetylcholinesterase enzyme, as well as moderately active against the tyrosinase enzyme. The antiglycation capacity of the extract followed this order: G. cordifolium leaves > stems > roots > flower. As a result, our study indicated that G. cordifolium extracts have strong antioxidant potential, good enzyme inhibitory effects and antiglycation potential. Further studies on G. cordifolium with in vivo bioassays need to be carried out to seek the importance of the plant in pharmaceutical techniques.","PeriodicalId":9161,"journal":{"name":"Botanica Serbica","volume":"51 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75654527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
