AB  - The present study investigated the antagonistic and plant growth promoting (PGP) 
      potential of actinobacteria TT3 isolated from tea rhizosphere soil of Tocklai tea 
      germplasm preservation plot, Jorhat, Assam, India. It is a Gram-positive, 
      filamentous with flexible spore chains actinobacteria. The 16S rRNA gene 
      sequencing and phylogenetic analysis indicated that TT3 is closely related to 
      genus Streptomyces for which it was referred to as Streptomyces sp. TT3. It 
      showed very promising PGP traits such as phosphate solubilization, production of 
      indole acetic acid (IAA), siderophore, and ammonia. Evaluation of ethyl acetate 
      extract of TT3 exhibited broad spectrum antagonistic activity against various 
      fungal pathogens. This antagonistic Streptomyces sp. TT3 showed positive for 
      polyketide synthase type II (PKS-II) gene, which was predicted to be involved in 
      the production of actinorhodin as a secondary metabolite pathway product using 
      DoBISCUIT database. Further, the crude ethyl acetate extract of TT3 was analyzed 
      by using GC-MS and revealed the presence of significant chemical constituents 
      responsible for antimicrobial activity. Thus, the present study suggests that 
      actinobacteria isolated from the rhizosphere soil may be explored for the 
      production of bioactive compounds and use as a potential candidate for tea and 
      other agricultural application.
