A comprehensive study of a typical steppe perennial Iris pumila L. were carried out in the central zone of the European part of this species’ range, namely in Ukraine. Intraspecific differentiation, population size and isolation degree and its consequences, the threat of human impact were analyzed, as well as ecological amplitude and genetic variation in ISSR markers and selected chloroplast regions...
Upon recent rediscovery of the dolichopodid Orthoceratium lacustre (Diptera: Dolichopodidae) in Flanders (northern Belgium) three sites with potential habitat of the species in Flanders were visited in September 2016. The survey revealed the presence of a population of the species at each site. In order to explain its apparent absence in Flanders for nearly the past 40 years, information on the distribution,...
Verticillium wilt causes devastating loss of yield and quality in many crops, including cotton. To determine the molecular mechanism of resistance to verticillium wilt in cotton, we isolated a new cytochrome P450 gene, CYP94C1, and analysed its function. We obtained the complete open reading frame, which encodes a protein of 500 amino acids. The results of the functional analysis showed that resistance...
Orchis forms a big group in terms of the number of species it includes, and studies conducted in recent years reveal results which are different from each other in terms of the systematics and phylogeny of the genus. In order to reveal both qualitative and quantitative seed properties of the species belongs to phylogenetically related genera in detail and to investigate which properties are diagnostic...
Economical as well as medicinal and nutritional benefits of Japanese quails are important. The aim of the present study was to investigate the effect of dietary inclusion of probiotics and humic acids on some antioxidant, carcass and egg production parameters of Japanese quails. As Japanese quails are an interesting animal model attracting attention in the last years, a partial aim of this study is...
The present study deals with histological descriptions of clinically healthy human gingivae through the methods of light, electron microscopy and immunohistochemistry. Even clinically healthy human gingivae are subject to constant bacterial and mechanical influences present in the oral cavity; therefore, the term “normal gingiva” is misleading. The aim of this study was to identify, in clinically...
Species distribution models are increasingly used in regional biodiversity assessments, pest management strategies, conservation biology, ecology and evolution. The Maximum Entropy model was applied to predict the potential distribution of four egg parasitoids, e.g., Psix saccharicola, Trissolcus agriope, Trissolcus basalis and Trissolcus volgensis (all Hymenoptera: Scelionidae) in Kerman province,...
Sarcophaga disputata Lehrer, 1967 is a poorly known Central European species. A detailed redescription of the male with a morphological study of the genitalia using light and electron microscopy was carried out. A terminology of different structures of the phallosome of Sarcophagini is discussed. A hypothesis is proposed suggesting that specific areas near the base of the gonites, which are covered...
One of the open problems in evolutionary ecology is signal reliability. While the view that signals need to be costly to be honest has attracted most attention, this type of signals may apply only to some contexts. Also, different views exist about the nature of costs involved in signal honesty, and the classification and examination of these costs remains controversial. Pigmentary-based colouration...
First records of the following species of the family Dolichopodidae are given for Armenia: Asyndetus latifrons (Loew, 1857), Sybistroma obscurella Fallen, 1823, Hercostomus chetifer (Walker, 1849), H. vivax (Loew, 1857), Chrysotimus molliculus (Fallén, 1823), Rhaphium discigerum Stenhammar, 1851, Sympycnus pulicarius (Fallen, 1823), Teuchophorus monacanthus Loew, 1859, and Xanthochlorus tenellus (Wiedemann,...
In the present work the gene expression levels and enzyme activity of phenylalanine-ammonia-lyase (PAL) were investigated in plants of the model legume Lotus japonicus under control and stress conditions. PAL is the key enzyme of the phenylpropanoid pathway, a route that involves numerous branches that lead to the production of a wide range of metabolites that can play an important role in the response...
Among the classified neglected infectious diseases, the Ebola virus (EboV) remains a challenging epidemic. This deadly virus has been reported as a category A bioweapon organism by the World Health Organization due to the serious threat it poses. To date, Ebola drug discovery proves challenging. Proteins need to be targeted at the relevant biologically active site for drug or inhibitor binding to...
A crossover design was used to study food preferences and capability of nutritional acclimation to different food sources in terrestrial isopods, which live in xeric environments, by using Armadillo officinalis as an experimental model. The foods chosen for this experiment were three fresh foods with different content of water (potato, carrot, lettuce), and a dry food (leaf of plane tree). In order...
Hypercholesterolemia has been considered as a risk factor for Alzheimer’s disease (AD). In addition to low density lipoprotein (LDL), oxidized LDL plays some roles in AD pathology. Neurodegenerative effect of oxidized LDL was supported by the increased oxidative stress in neurons. To further investigate the role of oxidized LDL, the present study aimed to test its effect on amyloid precursor protein...
A plasmid pCAMBIA1301 containing Pleurotus eryngii cellulase gene (PEcbh), under the control of Lentinus edodes glyceraldehyde-3-phosphate dehydrogenase (LEgpd) promoter, was constructed and used as an expression vector. The vector was transformed into the tissue of P. eryngii using Agrobacterium tumefaciens-mediated transformation (ATMT) method and 4 transformants (PET1-4) were obtained. The positive...
Although harvestmen (Opiliones) are among the best studied groups of arachnids in Europe from the faunistic point of view, there is still lack of available information on ecological requirements of the particular species. Habitat preferences that determine the distribution of species are largely determined by the habitat structure and microclimate. Besides other factors, these characteristics of habitats...
Eighteen bacterial strains were isolated from soil of an urban area located in a transition zone between the Atlantic Forest and Pampa biomes, in southern Brazil. These strains were screened for cellulolytic, lipolytic and proteolytic potentials. Eleven isolates (61%) were able to produce cellulolytic enzymes on carboxymethylcellulose (CMC) agar plates, 14 isolates (78%) were proteolytic on skim milk...
Invasive plants are non-native, but in most cases naturalised, species that have successfully spread outside of their native range. Aliens invaded all habitats, are competing with native plants, thus, after the direct destruction of habitats, invasions are recognised as the second largest danger for biodiversity. Northern Red Oak is one of the most common invasive tree species dispersed primarily...
Morphologically normal and fertile transgenic chickpea plants have been regenerated through a standardized transformation protocols. This protocol is based on the infection of apical meristem explants (AME) with Agrobacterium strain EHA105. The stain, carrying pCAMBIA2301 vector contained β-glucuronidase (uidA) gene and neomycin phosphotransferase (nptII) genes. Different explants of chickpea and...
The effects of increasing concentrations of cadmium (Cd) on the ultrastructure, Cd accumulation, nutrient elements contents, levels of chlorophyll pigments, hydrogen peroxide (H2O2), malondialdehyde (MDA), antioxidants, as well as the activities of antioxidant enzymes were investigated in the leaves of Hydrocharis dubia (Bl.) Backer. Cd exposure resulted in significant damage in chloroplasts and mitochondria,...
