Signals affecting biocontrol factor expression at a transcriptional level

Control of root diseases by biocontrol pseudomonads involves a blend of complementary mechanisms, the most prominent being antibiosis towards plant pathogens, degradation of virulence factors produced by pathogens and induction of defence mechanisms in host plants. Efficient competition for colonization sites and micro- and macro-nutrients in the rhizo-sphere is an important prerequisite for effective biocontrol van Loon et al. 1998 Lugtenberg et al. 2001 Compant et al. 2005 Haas and Defago...
