    Opis:
    Plant secondary metabolites have a variety of functions, including mediating relationships between organisms, responding to environmental challenges, and protecting plants against infections, pests, and herbivores. In a similar way, through controlling plant metabolism, plant microbiomes take part in many of the aforementioned processes indirectly or directly. Researchers have discovered that plants may affect their microbiome by secreting a variety of metabolites, and that the microbiome could likewise affect the metabolome of the host plant. Pesticides are agrochemicals that are employed to safeguard humans and plants from numerous illnesses in urban green zones, public health initiatives, and agricultural fields. The careless use of chemical pesticides is destroying our ecology. As a result, it is necessary to investigate environmentally benign alternatives to pathogen management, such as plant-based metabolites. According to literature, plant metabolites have been shown to have the ability to battle plant pathogens. Phenolics, flavonoids, and alkaloids are a few of the secondary metabolites of plants that have been covered in this study.

    Opis:
    Isolation of RNA from plants rich in secondary metabolites using commercial kits often results in contaminated preparations which are not suitable for downstream applications. Although many specific protocols appropriate for plants with a high content of phenolics, anthocyanins and polysaccharides have been developed, these are often expensive, time consuming and not applicable to different types of tissues. This study presents a simple and efficient modification of RNA extraction from different types of tissues using two commercial reagent kits. By simple improvement, we routinely obtained high-quality RNA of the following plants: the blackcurrant bush, black chokeberry bush, pear tree, apricot tree, apple tree, hardy kiwi, tangerine tree, highbush blueberry and cranberry plant.

    Opis:
    Invasive alien species are non-native plant species that displace native species and pose adverse effects to environment, ecosystem, economy, and human health by diminishing the growth of native plants and by exhibiting higher stress tolerance. In our present study, four invasive alien species, namely Lantana camara, Parthenium hysterophorous, Ricinus communis, and Ageratum conyzoides, were studied from different locations. Plants growing under natural environmental conditions were sampled at random in the vicinity of Jalandhar. To gain insights into the biochemical basis of invasiveness of these plants, the samples were subjected to chemical fingerprinting by using UV-Vis, fluorescent, and Fourier transform-infrared (FT-IR) techniques under natural abiotic stress conditions (moderate and hot conditions). Indices of oxidative stress, such as malondialdehyde (MDA), were also studied. MDA levels were enhanced under hot conditions. Elevated peaks (major and minor) were observed in UV fingerprinting during adverse abiotic conditions. Fluorescent spectroscopy also validated the enhanced levels of secondary metabolites. FT-IR spectroscopy confirmed the presence of alkaloids and phenolics during stress conditions. Peaks were identified as rutin, vanillic acid, ascorbic acid, and glutathione reduced. The obtained results showed that under stressful conditions, the studied plants may produce an increased level of metabolites that might play a role in minimizing the oxidative stress faced by these plants. It was concluded that the studied plants, namely P. hysterophorus, L. camara, R. communis, and A. conyzoides, have the potential to cope with abiotic stress such as high temperature, which could be the reason for their invasiveness and vast adaptability.

    Opis:
    Metabolity wtórne to bardzo różnorodna grupa związków chemicznych naturalnie produkowanych przez organizmy. Spełniają one funkcje sygnałów biochemicznych, które umożliwiają komunikację między organizmami. Te niskocząsteczkowe związki organiczne działają jako chemomediatory ekologiczne, pełniąc funkcje obronne, przywabiające, ułatwiające rozmnażania, a także regulacyjne. Metabolity wtórne produkowane są przez bakterie właściwe, promieniowce, grzyby, glony, a także zwierzęta. Poznanie budowy oraz właściwości biologicznych umożliwiło zastosowanie metabolitów wtórnych w produkcji ważnych leków, takich jak: antybiotyki, leki przeciwnowotworowe, przeciwbólowe, immunosupresyjne, obniżające poziom cholesterolu lub regulujące poziom cukru we krwi. Metabolity wtórne mogą być zastosowane także jako naturalne i mniej szkodliwe środki ochrony roślin zwalczające fitopatogeny. Wśród metabolitów wtórnych są również silnie działające związki toksyczne, jak np. mykotoksyny produkowane przez grzyby. W rozdziale dokonano przeglądu literatury na temat budowy, funkcji ekologicznych oraz znaczenia wybranych metabolitów wtórnych roślin oraz grzybów.
    Secondary metabolites are a very diverse group of chemical compounds naturally produced by organisms. They perform functions of biochemical signals and enable communication between organisms. They are low-molecular organic compounds and act as ecological chemomediators. They perform defensive, attracting, facilitating reproduction, and regulatory functions. Secondary metabolites are produced by bacteria, actinomycetes, fungi, algae, as well as animals. Knowledge of the structure and biological properties has made it possible to use secondary metabolites in the production of important drugs such as antibiotics, anticancer drugs, painkillers, immunosuppressants, cholesterol-lowering or blood sugar-regulating drugs. Secondary metabolites can also be used as natural and less harmful plant protection products to combat phytopathogens. Among secondary metabolites are also potent toxic compounds such as: mycotoxins produced by fungi. This chapter reviews the literature on the structure, ecological functions and importance of selected secondary metabolites of plants and fungi.

    Opis:
    This study was focused on the identification and quantification of betaxanthins using high-performance liquid chromatography with a diode array detector coupled to electrospray ionisation mass spectrometry (HPLC-DAD-ESI-MS) in leaves of various cultivars of Beta vulgaris (beet) and Gymnocalycium mihanovichii grafted cacti. In G. mihanovichii grafted cacti, four betaxanthins, namely histidine-Bx, histamine-Bx, serine-Bx, and proline-Bx, were tentatively identified in the yellow, orange, pink, and red varieties, with contents ranging from 0.09 to 1.55 mg/kg fresh weight (FW). Betaxanthins were not detected in the green cactus. Histidine-Bx was the prevailing betaxanthin compound in the majority of cultivars. Fifteen betaxanthins were successfully identified in the leaves of five B. vulgaris cultivars (cv.): Snow Ball, Boldor, Cylindra, Rhubarb, and Round Dark Red. Leaves of yellow beet (cv. Boldor) had the highest total betaxanthin content (20.4 mg/kg FW), while white beet (cv. Snow Ball) had the lowest one (3.43 mg/kg FW). The leaves of red cultivars had comparable betaxanthin contents, ranging from 13.4 to 18.8 mg/kg FW, similary to the yellow cultivar, indicating their potential as valuable sources of betaxanthins. There was no single dominant betaxanthin in B. vulgaris leaves. The leaves of B. vulgaris were found to be a richer source of betaxanthin than the grafted cactus G. mihanovichii, which opens up new prospects for research into the potential utilization of these compounds in the industry.

    Opis:
    Finding healing power in plants is an ancient idea, and people of all continents and civilization have been using plants in one form or the other for poultices or as decoctions. Alangium salvifolium (Linn), family Alangeaceae, is a tree that grows in the wild throughout India. The plant has been used in the Indian traditional system of medicine for skin diseases (e.g. leucoderma), articular diseases, and anti-inflammation, anti-poisonous, anti-pyretic, and anti-emetic requirements. However, no scientific evidence is available regarding its antimicrobial activity. An investigation of Alangium salvifolium as an antimicrobial activity agent is the objective of our present study. The ATCC culture used in this study was collected from department of Microbiology, G.M.C., Bhopal (M.P.). Shade dried crude powder (200 grams) of seed of Alangium salvifolium was separately extracted with methanol in a soxhelt apparatus. The Antimicrobial activities were then studied by applying the Disc–Diffusion method. Our results indicate that the observed antimicrobial activity of the fraction appears to be due to unknown secondary metabolites in it. H.P.L.C. (high performance liquid chromatography) and chemical studies may, thus be useful in analyzing the presence of unknown secondary metabolites in the fractions.

    Opis:
    The medicinal usage of silverweed herb (Anserinae herba) is primarily related to the presence of phenolic compounds. Three populations of silverweed (Potentilla anserina L.) occurring at the edges of arable fields in Podlasie area (north-eastern Poland) were compared in respect of the content and composition of phenolics. Herb collected from the investigated populations differed in the content of determined compounds. The tannin content was very low (0.81-0.91%). The total flavonoid content ranged from 0.48 to 0.60%. Phenolic acid content was much higher (1.38-2.26%). Three flavan-3-ols: (+)-catechin, (-)-epicatechin, and (-)-epigallocatechin, four flavonol glycosides: rutoside, quercetin-3-O-glucoside, isorhamnetin-3-O-glucoside, and kaempferol-3-O-glucoside, as well as one phenolic acid (ellagic acid) were identified as a_result of HPLC analysis of methanolic extracts from the investigated raw materials. The most considerable differences between populations concerned the content of (+)-catechin (87.0-199.3 mg × 100 g-1), (-)-epigallocatechin (141.9-290.6 mg × 100 g-1), and rutoside (192.3-386.0 mg × 100 g-1) in herb...

    Portulaca oleracea L. (Portulacaceae) is used as functional food and its nutritional and therapeutic properties are related to the high levels of organic and fatty acids, polyphenols, polysaccharides and cyclo-dopa amides. This study presents a strategy based on liquid chromatography – high resolution accurate mass spectrometry method (LC – HRAMS) and bioinformatic methods to analyze 33 purslane accessions originating from 11 floristic regions in Bulgaria together with 5 accessions of Greek provenance. Extracts were obtained by microwave extraction. Based on the LC-MS metabolic “fingerprints” of assayed samples, a purslane metabolic database was developed. LC-MS data were proceeded with Software application Compound Discover 2.0 (Thermo Fischer Sci., USA). Principal Component Analysis (PCA) combined with both descriptive and differential analyses were used to find marker metabolites to distinguish different geographical regions. The differential analysis of the Bulgarian and Greek samples allowed the identification of 50 marker metabolites. Based on accurate masses, retention times, fragmentation patterns in MS/MS, comparison with commercial standards and literature data, these secondary metabolites were identified after detailed analysis of Volcano-plots. For the first time, 29 compounds are reported. The identified compounds were used to perform a study of the biosynthetic pathways of purslane secondary metabolites using Kyoto Encyclopedia of Genes and Genomes (KEGG) software platform. The statistical treatments identified marker compounds that can be used to distinguish the origin of accession set. Combining LC-MS data with multivariate statistical analysis was shown to be effective in studying the purslane metabolites, allowing for integration of chemistry with geographic origin.

    Opis:
    Currently, climate change is disrupting life on Earth by causing imbalances in the biosphere. This work aimed to evaluate the impact of climate change on the content of primary and secondary metabolites and the yield of essential oil of Rosmarinus officinalis. Thus, the results of the conducted experiment show that the content of primary metabolites decreased with increasing temperature and decreasing precipitation along the experiment(proteins from 7.61% to 7.14%, carbohydrates from 6.92% to 5.64%, fats from 1.48% to 1.29% and dietary fiber from 4.96% to 4.22% and mineral composition: Ca from 7.67% to 5.98%, Mg from 8.61% to 7.01%, Fe from 7.53% to 7.21% and Mn from 6.85% to 3.97%), and the content of secondary metabolites increased in the second year when increasing the temperature by 5 °C and water stress by 50% (coumarin from 6.59% to 10.99%, saponins from 7.15% to 8.46%, tannin from 3.92% to 5.95%, alkaloids from 6.69% to 15.62% and flavonoid from 8.02% to 15.75%),but in the fourth year when the temperature continued to increase and water stress was 75% the content of secondary metabolites decreased (coumarin from 10.99% to 8.27%, saponins from 8.46% to 7.87%, tannin from 5.95% to 4.85%, alkaloids from 15.62% to 10.68% and flavonoid from 15.75% to 11.36%)and the same results were obtained for the yield of essential oil which increased in the second year and decreased in the fourth year. This GC analysis of the three essential oil samples shows that the majority of compounds in the three essential oils studied are cineole (S1:45.98%, S2:55.36%, S3:43.08%) followed by camphor (S1:17.44%, S2:21.44%, S3:21.56%) and Alpha-pinene (S1:9.30%, S2:8.34%, S3: 9.17%) and other compounds in low percentage.

    Opis:
    One of the aim of nature protection should be improving the knowledge of society about properties of observed organisms. It can be helpful in creating the properly ecological conspicuous. Some species of lichens, eg genus Usnea, Ramalina, Pseudevernia, Cetraria, were commonly used in medicine from antiquity time. Their therapeutic properties are connected with the presence of secondary metabolites, eg cetraric acid, furmarprotocetraric acid, usnic acid. Nowadays few of the lichens have still application in producing some pills, tablets, syrups, toothpastes. During field trips in Sowia Gora (Puszcza Notecka) some epigaeic lichens known from therapeutic properties were recorded. Suggestion of necessity of putting some information connected with therapeutic properties of species in the didactic table along the road of nature complexes characterized by high diversity of lichens is given. It permits to increase the level of interest in this group of species and ipso facto contribute to protection of lichens.
    Jednym z celów ochrony przyrody powinno być poszerzanie wiedzy społeczeństwa na temat właściwości obserwowanych organizmów. Może być to pomocne w kreowaniu właściwej świadomości prośrodowiskowej. Niektóre gatunki porostów, np. z rodzaju Usnea, Ramalina, Pseudevernia, Cetraria, były powszechnie wykorzystywane w medycynie od czasów starożytnych. Ich lecznicze właściwości powiązane są z obecnością metabolitów wtórnych, takich jak kwas cetrarowy, kwas furmaprotocetrarowy, kwas usninowy. Obecnie istnieje grupa porostów, która jest wykorzystywana przy produkcji tabletek, syropów, past do zębów. Podczas badań terenowych w okolicach Sowiej Góry (Puszcza Notecka) udało się zaobserwować interesujące porosty naziemne wykazujące właściwości lecznicze. W artykule zasygnalizowano konieczność umieszczania informacji na temat właściwości leczniczych porostów na tablicach o charakterze dydaktycznym w kompleksach przyrodniczych cechujących się dużym bogactwem gatunkowym porostów. Pozwoli to zwiększyć zainteresowanie tą omówioną grupą organizmów i tym samym przyczynić się do ochrony porostów.

    Opis:
    In vitro tissue culture technique, especially micropropagation, is attracting increasing attention in the production of ornamental plants. This technique will probably dominate the horticultural market in the near future. Light is one of the several factors affecting the success of in vitro plant tissue cultures. It directly affects the widely understood morphogenetic response of the explant, i.e., the ability of the explant to grow or regenerate, produce roots, etc. Lighting conditions provided during the in vitro stage may also greatly affect the plant vigor after transferring to nonsterile conditions. Moreover, the necessity of providing artificial light significantly contributes to the total cost of maintaining tissue cultures (related to energy consumption and the need to cool down the heat generated by lamps). Light quantity (intensity) and quality (spectral composition) are the two main parameters that determine its influence on in vitro cultures. This impact depends on the species and other accompanying factors. The aim of this mini-review is to summarize information on the influence of light on the morphogenetic and biochemical response of explants of some selected ornamental plant species grown under in vitro conditions.

    Opis:
    The natural occurrence of the shrimp (Penaeus monodon Fabricius, 1798) and seagrass (Cymodocea rotundata Asch. & Schweinf.) is found in the area of Indian Ocean, Indonesia, for central Pacific. Vibriosis can cause death in larvae, juvenile and adult shrimp almost close to 100%. Antibacterial substances from secondary metabolites are produced by plants and animals to reduce the use of synthetic antibiotics. The purpose of this research was to determine the ability of secondary metabolites contained in the bacterial extract of the association of sea grass Cymodocea rotundata (isolate code BA.1) to treat vibriosis in tiger shrimp (Penaeus monodon). This research was conducted at the Laboratory of Integrated Biotechnology and Laboratory of Aquaculture, Fisheries and Marine Sciences Faculty, Universitas Padjadajaran, and at the Brackish and Southern Ocean Aquaculture Development Center Pangandaran, from June to September 2018. The research method used was experimental, with completely randomized design (CRD) consisting of five treatments with three replications including; control treatment (concentration of 0 mg·L–1), 150 mg.L–1, 300 mg·L–1, 450 mg·L–1 and 600 mg·L–1. Observations made include clinical symptoms (morphology, behavior) and survival rate. Clinical symptoms of infected tiger shrimp during the in vivo test were red spots on the abdomen and necrosis of some leg and tail segments. The behavior of tiger shrimp mostly shows less responsive movements to fish-feed on the first day, and showing responsive and active behavior on the fifth day. In vivo test results for 14 days showed that the highest survival rate of 51.67% was in case of the addition of antibacterial extracts of BA.1 with a concentration of 300 mg·L–1.

    Opis:
    Neem has immense biocontrol potential against a large number of pathogens causing various diseases in human beings and plants. The plant has maximum useful value in its leaves, bark, flowers and fruits than any other tree species. These values include antiallergic, antidermatic, antifeedent, antifungal and anti-inflammatory properties. Due to the vast activities of neem, it has become extremely valuable in making our ecosystem a green treasure. Neem leaves have been demonstrated to exhibit immuno-modulatory, anti-inflammatory, antiulcer, antimalarial properties. Neem tree plant parts contain a promising pest control substance which has found effective use against economically important agricultural pests. Neem plant products are easy to process by village level industries on the micro scale level and use by resource poor farmers in crop protection resulting thereby in income generation. This plant also has antioxidant properties and free radical scavenging potential in its different extracted solvents. The present review highlights the properties of neem against the pathogens of living organisms for environmental protection.
