Journal ArticleDOI
The PGPR strain Phyllobacterium brassicacearum STM196 induces a reproductive delay and physiological changes that result in improved drought tolerance in Arabidopsis.
Justine Bresson,Justine Bresson,Fabrice Varoquaux,Thibaut Bontpart,Thibaut Bontpart,Bruno Touraine,Denis Vile +6 more
TL;DR: Rhizob bacteria-induced delay in flowering time could represent a valuable strategy for increasing biomass yield, whereas rhizobacteria-induced improvement of water use is of particular interest in multiple scenarios of water availability.
Journal ArticleDOI
Effects of rhizobacterial ACC deaminase activity on Arabidopsis indicate that ethylene mediates local root responses to plant growth-promoting rhizobacteria
Céline Contesto,Guilhem Desbrosses,Cécile Lefoulon,Gilles Béna,Florie Borel,Marc Galland,Lydia Gamet,Fabrice Varoquaux,Bruno Touraine +8 more
TL;DR: The results would suggest that rhizobacterial AcdS activity affects local regulatory mechanisms in plant roots, and not lateral root development that is under systemic regulation involving shoot–root dialog.
Journal ArticleDOI
The auxin-signaling pathway is required for the lateral root response of Arabidopsis to the rhizobacterium Phyllobacterium brassicacearum

TL;DR: In this paper, the root development response of Arabidopsis thaliana to inoculation with Phyllobacterium brassicacearum STM196 was investigated, and it was found that inoculation resulted in a 50% increase of lateral root growth in Arabidisopsis wild-type seedlings.
Journal ArticleDOI
The NRT2.5 and NRT2.6 genes are involved in growth promotion of Arabidopsis by the plant growth‐promoting rhizobacterium (PGPR) strain Phyllobacterium brassicacearum STM196
Maya Kechid,Guilhem Desbrosses,Wafaa Rokhsi,Fabrice Varoquaux,Abdelhamid Djekoun,Bruno Touraine +5 more
TL;DR: Findings demonstrate that NRT2.5 and N RT2.6, which are preferentially expressed in leaves, play an essential role in plant growth promotion by the rhizospheric bacterium STM196.
Journal ArticleDOI
PGPR-Arabidopsis interactions is a useful system to study signaling pathways involved in plant developmental control.
TL;DR: This work shows that studying the interaction between a PGPR and the model plant Arabidopsis is a useful system to uncover new pathways involved in plant plasticity, and indicates that root hair elongation induced by PGPR inoculation is probably an auxin-independent mechanism.
