Abstract

Fluorescent pseudomonads colonizing roots of crop plants and producing antifungal metabolites are regarded as a reliable alternative to chemical fungicides against soil-borne phytopathogens. Key factors in successful pathogen control are presence and activity at the appropriate concentration, time, and place of biocontrol agents. Thus, quantification methods to monitor population dynamics are pivotal to the development of reliable application protocols. Real-time PCR is nowadays the most widespread cultureindependent technique for the detection and enumeration of different target sequences. Here, its implementation with high resolution melting analysis as a powerful tool to accurately discriminate microbial inoculants is discussed.
