Comparative analysis of the genetic structure of a Rhizobium meliloti field population before and after environmental release of the highly competitive R. meliloti strain GR4

Autor: Pedro Burgos, Pablo J. Villadas, Doris Jording, Werner Selbitschka, Alfred Pühler, Nicolás Toro

Publikováno v: ResearcherID

Rhizobium meliloti strain GR4, which exhibits a highly competitive ability for alfalfa root nodule occupancy, was used in a field release experiment in Granada, Spain. In order to analyze the ecological impact of the GR4 release, we characterized the

The insertion sequence element ISRm2011-2 belongs to the IS630-Tcl family of transposable elements and is abundant in Rhizobium meliloti

Autor: Walter Arnold, Werner Selbitschka, Doris Jording, Nicolás Toro, Bob Kosier, Alfred Pühler

Publikováno v: Gene. 163:59-64

The insertion sequence (IS) element ISRm2011-2 of Rhizobium meliloti (Rm) is characterized by 19-bp imperfect terminal inverted repeats (three mismatches) and a size of 1053 bp. Upon transposition, ISRm2011-2 generates a putative target duplication o

Stationary-phase mutants of Sinorhizobium meliloti are impaired in stationary-phase survival or in recovery to logarithmic growth

Autor: Werner Selbitschka, Rainer Schmidt, Doris Jording, C Uhde, Alfred Pühler

A screening method was used to identify Sinorhizobium meliloti mutants which are affected in stationary-phase survival. Of 20,000 individual colonies mutagenized with transposon Tn5-B20, 10 mutant strains which showed poor or no survival in the stati

Construction and characterization of a Rhizobium leguminosarum biovar viciae strain designed to assess horizontal gene transfer in the environment

Autor: Rainer Schmidt, Doris Jording, Penny R. Hirsch, Werner Selbitschka, Tom A. Mendum, Alfred Pühler, Stefan Nieman

Publikováno v: FEMS microbiology letters. 128(3)

An integration vector was developed which inserts cloned DNA in a non-essential site of the Rhizobium leguminosarum biovar viciae chromosome. The expression of integrated genes is under the control of the constitutive neomycin phosphotransferase II (

Molecular analysis of the Rhizobium meliloti mucR gene regulating the biosynthesis of the exopolysaccharides succinoglycan and galactoglucan

Autor: Alfred Pühler, Doris Jording, Jürgen Quandt, Walter Arnold, Wm Weng, A Roxlau, M. Keller, Karsten Niehaus, Michael Schmidt

Publikováno v: Molecular plant-microbe interactions : MPMI. 8(2)

The Rhizobium meliloti Tn5 mutant Rm3131, producing galactoglucan (EPS II) instead of succinoglycan (EPS I), was complemented by a 3.6-kb EcoRI-fragment of the Rhizobium meliloti genome. Sequencing of this fragment revealed six open reading frames (O

THE C-4-DICARBOXYLATE TRANSPORT-SYSTEM OF RHIZOBIUM-MELILOTI AND ITS ROLE IN NITROGEN-FIXATION DURING SYMBIOSIS WITH ALFALFA (MEDICAGO-SATIVA)

Autor: Doris Jording, C Uhde, Alfred Pühler, Romy Schmidt

The Rhizobium meliloti C-4-dicarboxylate transport (Dct) system is essential for an effective symbiosis with alfalfa plants. C-4-dicarboxylates are the major carbon source taken up by bacteroids. Genetic analysis of Dct-mutant strains led to the isol

Regulation of the C4-dicarboxylate transport in free-living and symbiotic Rhizobium meliloti

Autor: Doris Jording, Parveen K. Sharma, Thomas Engelke, Alfred Pühler

Publikováno v: Nitrogen Fixation ISBN: 9781468464344

Nitrogen fixation in the Rhizobium-legume symbiosis is an energy demanding process. The plant supplies energy to the bacteroid and receives in return, fixed nitrogen. C4-dicarboxylates are considered to be the compounds which are provided by the plan
