Short description of the thesis

Plant roots are crucial for water and nutrient uptake and play a central role in interactions with beneficial soil microorganisms. This doctoral dissertation investigates how plant growth-promoting rhizobacteria (PGPR) reshape root development in barley and wheat. Combining molecular biology, physiology, genetics, and microbiome approaches, the study shows that PGPR-induced root developmental changes are associated with coordinated shifts in hormone signaling, carbohydrate metabolism, and ROS homeostasis. The dissertation further demonstrates that plant responses to PGPR are influenced by genetic background and environmental conditions. Together, these findings provide new insights into plant->microbe interactions and support microbiome-informed strategies for sustainable crop improvement.
