Charles,Xiaoyulong Chen,Luca Simone Cocolin,Kellye Eversole,Gema Herrero Corral,Maria Kazou,Linda L. Kinkel,Lene Lange,Nelson Lima,Alexander Loy,James Macklin,Emmanuelle Maguin,Tim H.

Singh,Michael Wagner,Aaron M. Walsh,Angela Sessitsch,Michael Schloter +33 more
TL;DR: A definition of microbiome is proposed based on the compact, clear, and comprehensive description of the term provided by Whipps et al. in 1988, amended with a set of novel recommendations considering the latest technological developments and research findings.
Journal ArticleDOI
Restoration of growth of durum wheat (Triticum durum var. waha) under saline conditions due to inoculation with the rhizosphere bacterium Azospirillum brasilense NH and extracts of the marine alga Ulva lactuca.
Elhafid Nabti,Mohamed Sahnoune,Mostefa Ghoul,Doreen Fischer,Andreas Hofmann,Michael Rothballer,Michael Schmid,Anton Hartmann +7 more
TL;DR: The rhizosphere bacterium Azospirillum brasilense NH, originally isolated from salt-affected soil in northern Algeria, greatly enhanced growth of durum wheat under saline soil conditions and could effectively provide alone or in combination with extracts of U. lactuca a promising solution to overcome salt inhibition which is a major threat hindering productive wheat cultivation in arid saline soils.
Journal ArticleDOI
Molecular characterisation of the diazotrophic bacterial community in uninoculated and inoculated field-grown sugarcane (Saccharum sp.)
Doreen Fischer,Barbara Pfitzner,Michael Schmid,Jean Luiz Simões-Araújo,Veronica Massena Reis,William Pereira,Ernesto Ormeño-Orrillo,Brigitte Hai,Andreas Hofmann,Michael Schloter,Esperanza Martínez-Romero,José Ivo Baldani,Anton Hartmann +12 more
TL;DR: Known as well as yet uncultivated diazotrophs were found active in sugarcane roots and stems using molecular analyses, and should help to better understand the basis of the biological nitrogen fixation (BNF) activity of a high nitrogen fixing Sugarcane variety.
Journal ArticleDOI
Dynamic regulation of N-acyl-homoserine lactone production and degradation in Pseudomonas putida IsoF.
Agnes Fekete,Christina Kuttler,Michael Rothballer,Burkhard A. Hense,Doreen Fischer,Katharina Buddrus-Schiemann,Marianna Lucio,Johannes Müller,Philippe Schmitt-Kopplin,Anton Hartmann +9 more
TL;DR: This study suggests that AHL degradation is an integral part of the whole autoinducer circuit of P. putida IsoF, allowing quantitative predictions and a further understanding of the QS-based regulations in this bacterium.
Journal ArticleDOI
Cowpea Nodules Harbor Non-rhizobial Bacterial Communities that Are Shaped by Soil Type Rather than Plant Genotype.
Jakson Leite,Doreen Fischer,Luc Felicianus Marie Rouws,Paulo Ivan Fernandes-Júnior,Andreas Hofmann,Susanne Kublik,Michael Schloter,Gustavo Ribeiro Xavier,Viviane Radl +8 more
TL;DR: The aim of this work was to describe the diversity of bacterial communities associated with cowpea root nodules using 16S rRNA gene amplicon sequencing, regarding the factors plant genotype and soil type.
