Popis: Certain rhizobacteria referred to as 'plant growth-promoting rhizobacteria' (PGPR) can contribute to the biological control of plant pathogens and improve plant growth. They enhance root development either directly by producing phytohormones, or indirectly by inhibiting pathogens through the synthesis of different compounds. PGPR are likely to be of great interest in sustainable crop protection and have drawn much attention in recent years. However, the use of these bacteria to protect crops sometimes fails because rhizobacteria are unable to recolonize the rhizosphere of inoculated plants. The colonization of roots by inoculated bacteria is an important step in the interaction between beneficial bacteria and the host plant. However, it is a complex phenomenon influenced by many biotic and abiotic parameters, some of which are now apparent. This paper summarises knowledge on rhizosphere colonization by PGPR.
