Bisphenol A (BPA) is a widely used chemical, that can potentially be toxic to plants. In this study we examined the toxicity of 5-50 mg/l BPA on Arabidopsis thaliana. Additionally, effects 0.5-5 were after four weeks development. had no effect germination rate and chlorophyll a/b ratio. The carotenoid content was significantly elevated in seedlings treated with 5 BPA. 4-week-old plants there change photosynthetic parameters (Fv/Fm, Fv/F0 PI) unaffected, which suggests photoinhibition. No...
Copper is an essential micronutrient, but at supraoptimal concentrations it also highly toxic, inducing oxidative stress and disrupting photosynthesis. The aim of the present study was to analyze selected protective mechanisms in strains Chlamydomonas reinhardtii adapted not for growth presence elevated copper concentrations. Two algal lines (tolerant non-tolerant high Cu
Abstract The existence of European ash ( Fraxinus excelsior L.) is threatened by fungus-induced dieback. It essential to find effective methods multiply genotypes resistant dieback while preserving the genetic diversity these tree populations. In this paper efficient method for production seedlings using indirect auxiliary organogenesis with multi-factor analysis its effectiveness presented. Procedures a dormancy breaking treatment seeds and disinfection F. primary explants, as well...
<p>Two <em>Chlamydomonas reinhardtii</em> CW15 populations modified by an excess of copper in growth medium were obtained: a “Cu” population that was continuously grown under the selection pressure 5 µM Cu<sup>2+</sup> (for at least 48 weeks) and “Re” population, where relatively short (9 week) exposure to elevated copper, necessary for acquiring tolerance, followed prolonged period (at 39 cultivation normal (0.25 µM) concentration.</p><p>Cells Cu...
Chlamydomonas reinhardtii (WT 2137) P. A. Dang. (Volvocales, Chlorophyceae) is a green microalgae serving as suitable model in scientific research and promising industrial biotechnology platform for production of biofuel, hydrogen recombinant proteins. Fullerenes (C60) are allotropic carbon nanoparticles discovered 1985 used biomedical studies since the early 1990s, when water solubilization methodologies were developed. Recently, surface-modified hydroxylated derivatives fullerenes proven...
Abstract Hybridization and introgression are important processes influencing the genetic diversity evolution of species. These particular importance in protected areas, where they can lead to formation hybrids between native foreign species may ultimately result loss parental from their natural range. Despite importance, contribution hybridization Sorbus genus remains not fully recognized. We analysed morphological variability several including (Sorbus aria), (S. intermedia) potentially...
Abstract Avian blood parasites play a crucial role in wildlife health and ecosystem dynamics, exhibiting heterogeneous spatial distribution influenced by various factors. Although factors underlying heterogeneity infection with have been explored many avian hosts, their importance the context of host species parasite taxon remains poorly understood, particularly cohabiting species. Using next-generation sequencing for screening, we investigate association between Haemoproteus , Plasmodium...
Abstract Despite being an essential micronutrient, copper is also a potentially toxic heavy metal. Using selection experiments, we produced Chlamydomonas reinhardtii populations with increased tolerance of ions and then derived pure cell lines from these populations. Strains the same population (both adapted nonadapted) significantly differed in terms growth parameters. Cultivation strains range ion concentrations revealed differences photosynthetic performance, which could be attributed to...
Callus from Nicotiana tabacum is used as a model in plant developmental research. We tested several phytohormone (Indoleacetic acid - IAA; 2,4-Dichlorophenoxyacetic 2,4-D; kinetin KIN; 6-Benzylaminopurine BAP) combinations to compare different approaches callus induction directly the seeds of tabacum. formation was observed up 4 weeks after sowing and most effective were 0.5 mg/L 2,4-D with 0.25 BAP 2 1 BAP. The calli green, photosynthetically active 6 growth, no stress symptoms (estimated...
