My work focus on the application of Plant-Growth-Promoting Bacteria (PGPB) in agriculture. Over the past few decades, PGPB have been used as organic fertilizers or biocontrol microorganisms to reduce the use of chemicals in agricultural production. The future trend of bio pesticide development is to meet the needs of various agricultural production in a single product, and minimize the adverse effects on growers, crops and the environment. By further research of PGPB, we aim to explore the potential of PGPB to limit the number of weeds in crop field or to reduce the harm of residual herbicides to the later crops.

Endophytic PGPR Burkholderia phytofirmans PsJN (Bp) promotes growth of various plants andtriggers protection against several environmental stresses. To get more insights into the interaction between plant and Bp, we focused on leaf physiological and metabolic aspects of Arabidopsis thaliana. We also determined the mechanisms involved in the defense of leaves after inoculation of the bacteria followed by an abiotic (cold) or a biotic (Pseudomonas syringae pv. tomato DC3000, Pst) stress. Our results show that the induction of growth promotion of A. thaliana by Bp could be related to the accumulation of primary metabolite levels (amino acids, soluble carbohydrates and vitamins) and to the variation of hormone levels in the leaves. Leaf physiology and metabolism are changed locally and distally by Bp epi- and endophytic colonization. In addition, changes in metabolite levels are more pronounced after a relatively long interaction between plant and bacteria. Moreover, Bp inoculation can also reduce cold injury on the photosynthetic activity by a non-stomatal limitation of photosynthesis and accumulation of photosynthetic pigments. Finally, the local presence of Bp causes a delay in the development of Pst, but only in the early stages of the infection. However, the inoculation with Bp does not protect the photosynthetic apparatus during Pst attack. Thus, our results emphasize that the time of presence of a PGPR and his location in the plant couldinfluence the plant physiology and stress tolerance.
