Diversity of Endophytic Actinomycetes from Wheat and its Potential as Plant Growth Promoting and Biocontrol Agents
A total of 35 endophytic actinomycetes strains was isolated from the roots, stems and leaves tissues of healthy wheat plants and identified as Streptomyces sp. (24), Actinopolyspora sp. (3), Nocardia sp. (4), Saccharopolyspora sp. (2) Pseudonocardia (1) and Micromonospora sp. (1). Seventeen endophy...
