Opis:: The objective of the present study was to evaluate the antibacterial properties of a plant secondary metabolite - caffeine. Caffeine is present in over 100 plant species. Antibacterial activity of caffeine was examined against the following plant-pathogenic bacteria: Ralstonia solanacearum (Rsol), Clavibacter michiganesis subsp. sepedonicus (Cms), Dickeya solani (Dsol), Pectobacterium atrosepticum (Pba), Pectobacterium carotovorum subsp. carotovorum (Pcc), Pseudomonas syringae pv. tomato (Pst), and Xanthomonas campestris subsp. campestris (Xcc). MIC and MBC values ranged from 5 to 20 mM and from 43 to 100 mM, respectively. Caffeine increased the bacterial generation time of all tested species and caused changes in cell morphology. The influence of caffeine on the synthesis of DNA, RNA and proteins was investigated in cultures of plant pathogenic bacteria with labelled precursors: [3H]thymidine, [3H]uridine or 14C leucine, respectively. RNA biosynthesis was more affected than DNA or protein biosynthesis in bacterial cells treated with caffeine. Treatment of Pba with caffeine for 336 h did not induce resistance to this compound. Caffeine application reduced disease symptoms caused by Dsol on chicory leaves, potato slices, and whole potato tubers. The data presented indicate caffeine as a potential tool for the control of diseases caused by plant-pathogenic bacteria, especially under storage conditions.

Opis:: Flavanones, secondary plant metabolites, are one of the main group of flavanoids. They are widely spread in nature in many plants. The large diversity of structural structure of flavanones and controlled methods of modifying their molecules have a huge impact on biological activity. The present review will summarize the current knowledge about occurrence, obtaining by chemical synthesis, application and bioactivity of flavanones. Also, they are received from specific chemical synthesis. Flavanones have a great biological activity. Derivatives of flavanone have many different properties such as anti-inflammatory, anticancer, antioxidant, antimicrobial or hepatoprotective activities. These natural polyphenolic compounds are used in cosmetology, pharmacy and medicine. The demand and usage on them increases.

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:: Lavender (Lavandula angustifolia) is a shrub of the family Lamiaceae, native to the Mediterranean region. The material used for herbal purposes includes lavender flowers (Lavandula flores) containing essential oil (3%), anthocyanins, phytosterols, sugars, minerals, and tannins. The qualitative and quantitative composition of the essential oil of lavender is variable and depends on genotype, growing location, climatic conditions, propagation, and morphological features. The essential oil contains over 300 chemical compounds. The dominant components are linalool, linalyl acetate, terpinen-4-ol, acetate lavandulol, ocimene, and cineole. Lavender essential oil has good antioxidant and antimicrobial activities and a significant positive effect on the digestive and nervous systems. Lavender extract prevents dementia and may inhibit the growth of cancer cells, while lavender hydrolate is recommended for the treatment of skin problems and burns.
Lawenda wąskolistna (Lavandula angustifolia) to krzewiasta roślina z rodziny jasnotowatych (Lamiaceae), pochodząca z terenów basenu Morza Śródziemnego. Surowcem zielarskim są kwiaty lawendy (Lavandula flores), zawierające olejek eteryczny (do 3%), antocyjany, fitosterole, cukry, związki mineralne i garbniki. Skład jakościowy i ilościowy olejku eterycznego z lawendy jest zmienny i zależy od genotypu, miejsca uprawy, warunków klimatycznych, sposobu rozmnażania i cech morfologicznych. W olejku eterycznym wstępuje ponad 300 związków chemicznych, składnikami dominującymi są linalol, octan linalilu, terpinen-4-ol, octan lawandulolu, ocymen oraz cyneol. Olejek eteryczny charakteryzuje dobra aktywność przeciwdrobnoustrojowa i antyoksydacyjna oraz wyraźny pozytywny wpływ na układ trawienny i nerwowy. Ekstrakt z lawendy przeciwdziałała otępieniu oraz może wpływać hamująco na rozwój komórek rakowych, zaś hydrolat lawendowy zalecany jest w leczeniu problemów skórnych i poparzeń.

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.
