AB  - Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse. Spray of rice seedling-leaves with of mixed spore suspension of the pathogen and S. sindeneusis isolate 263 resulted in strong inhibition of the pathogen and suppression of leaf symptoms. Propagation of the antagonist crude sap was performed in aqueous cultures and bioactivity was monitored in shaked cultures. Ongoing goals of this research include isolation, characterization and identification of the active metabolites and future  goals  include  identification  of  active  genes  for  use  in  development of   recombinant  DNAs  in  transgenic  rice  varieties  bearing   elevated  resistance  to infections by M. oryzae.
