ABSTRACT It was previously demonstrated that there are no indigenous strains of Bradyrhizobium japonicum forming nitrogen-fixing root nodule symbioses with soybean plants in arable field soils Poland. However, bacteria currently classified within this species present (together canariense ) as populations specific for nodulation legumes the Genisteae tribe. These rhizobia, infecting such lupins, well established Polish soils. The studies described here were based on experiments, at Poznań...
Plant interactions with environmental factors cause changes in the metabolism and regulation of biochemical physiological processes. defense against pathogenic microorganisms depends on an innate immunity system that is activated as a result infection. There are two mechanisms triggering this system: basal perception microbe-associated molecular patterns through pattern recognition receptors situated cell surface effector-triggered (ETI). An induced biosynthesis bioactive secondary...
The aim of the study was to examine cross-talk interactions soluble sugars (sucrose, glucose and fructose) infection caused by Fusarium oxysporum f.sp. lupini on synthesis genistein in embryo axes Lupinus luteus L.cv. Juno. Genistein is a free aglycone, highly reactive with potential inhibit fungal development plant diseases. As signal molecules, strongly stimulated accumulation isoflavones, including genistein, expression isoflavonoid biosynthetic genes. Infection significantly enhanced...
The aim of this study was to investigate the effect an abiotic factor, i.e., lead at various concentrations (low causing a hormesis and high toxicity effects), on generation signalling molecules in pea (
The aim of the study was to examine cross-talk exogenous nitric oxide (NO) and sucrose in mechanisms synthesis accumulation isoflavonoids embryo axes Lupinus luteus L. cv. Juno. It verified whether interaction these molecules can modulate defense response infection development pathogenic fungus Fusarium oxysporum f. sp. lupini. Sucrose alone strongly stimulated a high level genistein glucoside pretreated with (SNP or GSNO) non-pretreated axes. As result amplification signal coming from GSNO,...
The aim of this study was to investigate the effect exogenous nitric oxide (NO), i.e., S-nitrosoglutathione (GSNO) and sodium nitroprusside (SNP), on metabolic status Pisum sativum L. cv. Cysterski leaves infested by Acyrthosiphon pisum Harris, population demographic parameters A. feeding activity. A reduction in level semiquinone radicals pea seedling pretreated with NO occurred 24 h after infestation, which earlier than non-pretreated leaves. decrease O2•− observed GSNO aphids at 48 72...
The main aim of this study was to understand the regulation biosynthesis phytohormones as signaling molecules in defense mechanisms pea seedlings during application abiotic and biotic stress factors. It important identify at molecular level Pisum sativum L. under influence various concentrations lead—i.e., a low concentration increasing plant metabolism, causing hormetic effect, high dose sublethal effect—and feeding phytophagous insect with piercing-sucking mouthpart—i.e., aphid...
Pseudomonas aeruginosa biofilm-associated infections are a serious medical problem, and new compounds therapies acting through novel mechanisms much needed. Herein, the authors report ruthenium(IV) complex that reduces P. PAO1 biofilm formation by 84%, alters morphology living-to-dead cell ratio at 1 mM concentration. Including compound in culture medium altered pigments secreted PAO1, fluorescence spectra revealed decrease pyoverdine. Scanning electron microscopy showed ruthenium did not...
Abstract Investigations of bacterial communities and characterization mineralogy the environment in Złoty Stok As-Au deposit were carried out. PXRD analysis revealed presence picropharmacolite as most common secondary arsenic mineral mine. Total DNA was extracted from slime streams or biofilms samples to investigate communities. PCR amplification 16S rDNA performed followed by subcloning its products. Over 170 clones analyzed means RFLP method. Eight group representing different restriction...
Abstract Understanding the complexity and biodiversity of fungal communities associated with wheat endosphere can facilitate identification novel strains that might be beneficial to host plant. However, differentiation taxonomic classification endosphere-associated fungi respect various cultivars plant organs are challenging, time-consuming, expensive, even use molecular techniques. In present work, we describe a fast, simple, low-cost method based on high-resolution melting PCR (HRM-PCR)...
Microorganisms in the environment rarely live as single planktonic cells.Most often they form a static consortium of microorganisms floating mucus.Nowadays, those consortiums are described biofilm or biolayer [1-2].Biofilm is very complex and dynamic structure which microbial cell cooperates functions like multicellular organism.Biofilms can be formed by bacteria, fungi, algae, well protozoans.Those multi-culture 3-D structures built one many groups have an ability to attach biological...
Soybean [Glycine max (L.) Merr.] is one of the most important and oldest crops. Due to its ability form symbiotic interactions with nitrogen-fixing bacteria, it a valuable source nitrogen for agriculture proteins humans livestock. In Europe, instance, in Poland, soybean cultivation area still not large but gradually increasing due climate change. The lack indigenous microsymbionts Polish soils forces application commercial strains establish effective symbioses. Fast reliable identification...
