The diversity of culturable endophytic actinomycetes related to plants and especially medicinal plants are isolated and characterized. The increased colonization and distribution of endophytic actinomycetes in plants have been reported in many studies. Endophytic actinomycetes belong to different genera are distributed in plants species such as Streptomyces, which is the dominant genus, Micromonospora, Microbispora, Nocardiopsis, Rhodococcus and Nocardia. Moreover, there are many novel strains had been described belong to these genera. Endophytic actinomycetes seem to contribute with plant development and displaying beneficial traits that can be exploited in plant maintenance, substances supplements, protection and defense. Colonization of endophytic actinomycetes in plant tissues are largely influenced by plant species and the environmental factors surrounding the host plants such as soil pH, water content, rainfall, soil salinity, and temperatures. Some endophytic actinomycetes may occur in low numbers and sometimes in localized positions within the plant. Thus, this review summarizes an aspect of the diversity and colonization of endophytic actinomycetes, including their mechanism of action, importance, and isolation and identification methods.
