Abstract/Contents:"Soil and rhizosphere microorganisms are believed to play important roles in turfgrass health. However, the specific microorganisms and the microbial processes that contribute to improved turf health are poorly understood in many cases and in some cases completely elusive. A serious limitation to our understanding of the microbial ecology of turfgrass soils has been the lack of suitable methods for studying the diversity, distribution, and behavior of soil and rhizosphere microorganisms. Traditional methods have commonly relied on a variety of culturing techniques. However, only a small fraction (<0.1%) of the soil microbial community has been accessible with this approach. Culture-independent methods that overcome some of these limitations have been developed over the past 10 years. Most notable of these are molecular methods in which genes are amplified from soil-extracted nucleic acids, sequenced, and either compared with databases of similar sequences from previously-studied microorganisms or used to develop group- and taxon-specific oligonucleotide probes. Recently, developments in functional genomics have provided new opportunities for understanding the microorganisms and processes that contribute to improved plant health. Examples with disease suppressive soils and microbial inoculants will be used to illustrate various approaches for the study of turfgrass microbial ecology."
