This work is the completion of a series reports describing nitrogen-fixing bacterial symbionts sulla (Hedysarum coronarium L., Leguminosae) and providing grounds for their proposal as new taxon. The introduction summarizes large amount previous evidence gathered on physiology, genetics ecology such organisms, which have in past been referred to provisionally 'Rhizobium hedysari'. Upon adding 16S RNA sequencing, amplified rDNA restriction analysis rrn operon, DNA-DNA hybridization homology...
There is increasing evidence that communication between members of the same species, as well different important for survival microorganisms in diverse ecological niches, such rhizosphere. To investigate whether phytopathogen Pythium ultimum could alter gene expression biocontrol strain Pseudomonas fluorescens F113, which protects roots sugar beet from fungus, a screening system was developed to detect differential bacterial genes presence P. ultimum. The transposon Tn5, containing...
Pseudomonas fluorescens F113 produces antifungal metabolites that protect the roots of sugarbeet from fungus Pythium ultimum . The phytopathogen, in turn, has ability to downregulate expression genes fundamental rhizosphere competence bacterial strain. This paper describes characterization two these genes, which were isolated by screening a mini‐Tn 5 :: lacZ mutant bank for differential β‐galactosidase presence P. In order identify affected reporter mutants SF3 and SF5, transposons flanking...
Summary We have devised a rapid four‐step procedure for the generation of directed and unmarked chromosomal deletions in bacteria, based on use novel cloning vector containing Bacillus subtilis sacB gene that encodes levansucrase confers sucrose sensitivity, which can be used counter‐selection. Using this technique, we describe construction 6.5 kb deletion phytopathogenicity region chromosome Xanthomonas campestris. This allows easy transfer wide variety mutant allelic DNA to bacterial...

Science blogging is a very useful system for scientists to improve their work, keep in touch with other colleagues, access unfamiliar science developed fields, open new collaborations, gain visibility, discuss the public. To favour building of blog communities, some media have set up networks hosting scientists' blogs, like ScienceBlogs.com or Nature Network. With interesting features and many potential uses.
We have examined the diversity of glycoconjugates and cellular lipids Rhizobium "hedysari" IS123, a bacterial symbiont that specifically nodulates drought-tolerant forage legume Hedysarum coronarium. IS123 develops complete capsule consisting loose fibrillar network ruthenium-red-staining acidic polymers produces two different exopolysaccharides (EPS). EPS-A contains glucose, galactose, mannose, noncarbohydrate substitution tentatively identified as lactyl ester. The composition EPS-B, which...
In the midst of a debate on access to information, World Health Organization and FAO have decided develop strategy guarantee right poor countries free scientific publications. This is often denied, mainly because high subscription costs. For this reason, universities research centres in southern must forego buying magazines, which are valuable instrument for updating, exchanging information issues. choice has been made an historical period when industrialized world marked by knowledge-based economy.
