Beneficial plant-microorganism interactions: from genomes to chemical signals

(G. Comte, D. Muller, C. Prigent-Combaret, F. Wisniewski-Dyé)

Image thème 1_texte

Mechanisms involved in phytobeneficial effects (phytohormones, antimicrobial compounds, N fixation, P solubilization, defense induction, etc.).

Chemical mediators of these interactions (UPLC-QTOF and CPG-QQQ analyses, CESN platform) (theses A. Lautrey, A. Ballot; post-doctorate T. Lurthy)

Microbial biosynthetic pathways and their regulation (sequencing and annotation of new genomes of phytobeneficial microorganisms, thesis A. Ballot)

Physiological responses in host plants (RNAseq) (theses A. Lautrey, A. Ballot)

Mechanisms of coevolution between plants and phytobeneficial microorganisms (Experimental evolution on microbial communities in planta).

The ecological role of root microbiota

(J. Almario, Y. Moënne-Loccoz, D. Muller, C. Prigent-Combaret)

  • Study/monitoring of phytobeneficial functional groups (nitrogen fixers, phytohormone producers...) and their impact on plant growth (qPCR, metabarcoding, metagenomics)
  • Plant-microbiota coevolution impact of plant genotype and domestication/selection processes on root microbiota functioning (identification of QTL involved in phytobeneficial interactions in collaboration with GDEC; thesis C. Gruet)
  • Root microbiota and plant phosphorus nutrition, focus on non-mycorrhizal plants (CNRS E2CO MicroPhos project; J. Almario, Y. Moënne-Loccoz)
  • Root microbiota and plant resistance to disease, the case of disease-resistant soils (qPCR, metabarcoding, metagenomics) (Analysis of microbial networks contributing to plant protection; thesis I. Todorovic, EU Biodiversa SuppressSOIL project, https://www.biodiversa.org/1778/download)
