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...
Genetic structure in field populations of Bradyrhizobium japonicum isolated Poland was determined by using several complementary techniques. Of the 10 sites examined, only 4 contained indigenous B. strains. The Polish bradyrhizobia were divided into at least two major groups on basis protein profiles polyacrylamide gels, serological reaction with polyclonal antisera, repetitive extragenic palindromic PCR fingerprints genomic DNA, and Southern hybridization analyses nif nod gene probes....
Reciprocal grafting experiments done using soybean plant introduction genotypes indicated that restriction of nodulation by Bradyrhizobium japonicum is determined the genotype root and dependent on growth temperature. Microscopic analyses restrict B. at symbiotic stages which occur both before after formation nodule primordia.
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...
A genetic locus in fast-growing Rhizobium japonicum (fredii) USDA 191 (Fix+ on several contemporary soybean cultivars) was identified by random Tn5 mutagenesis as affecting the development and differentiation of root nodules. This mutant (MU042) is prototrophic shows no apparent alterations its surface properties. It induces aberrant nodules, arrested at same early level differentiation, all host plants. An 8.1-kilobase EcoRI fragment containing cloned from MU042. In well another strain,...
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...
A procedure for in situ hybridization of nucleic acids was applied order to detect chromosomal DNA sequences coding leghemoglobin Vicia faba L. genome. Tritiated cDNA from Lupinus lutus used as a probe. Three different site localized three chromosomes (I, II and IV) were found.
