Kinkel. 1 computer file (PDF); vii, 187 pages, appendix p.163-187.This work explores a variety of mechanisms through which plants impact associated streptomycete communities. Streptomycete antibiotic-mediated antagonistic activity is a particular focus. Plant host species and plant richness are addressed as independent and interacting factors driving impacts on associated soil microbial communities. The possibility of modification to antagonistic phenotypes through chemical signaling between plants and streptomycetes is explored.en-USDiversityMicrobial ecologyStreptomycesStreptomycetePlant PathologyThesis or Dissertation
