Description of the research topic:
A major challenge in the agriculture is to respond to different biotic and abiotic factors that affects plant growth and productivity. Plants respond to abiotic stress factors (low and high temperature, salinity, drought) and defend mechanisms are induced in plant’s organism. Plant growth promoting rhizobacteria (PGPR) are able to increase the stress tolerance of plants due to different secondary metabolites as plant hormones, enzymes and antioxidants. The secondary metabolites have a role in reactive oxygen species (ROS) neutralization and induce the plant systemic resistance. Therefore the metabolites produced by PGP rhizobacteria are important in plant stress tolerance.
After the recognition of PGP rhizobacteria associated molecular patterns (MAMP - microbe associated molecular pattern) in plants molecular cascades are activated that strengthens the plant systemic resistance (ISR - induced systemic resistance). After the first activation (priming) the plants became able to respond faster and stronger to the environmental stimuli. Priming then increases the abiotic stress tolerance in plants.
The aim of this research is the identification of metabolites with role in PGPR bacterial induced priming in plants with role in abiotic stress tolerance.
