Endophytes (bacteria or fungi) are a major class of plant symbionts that live within their hosts. These endosymbionts provide a diverse hub of bioactive secondary metabolites, phytohormones, extracellular enzymes and essential nutrients. In return, the host provides a protective habitat and access to the nutrients needed to reproduce and grow during the endophyte’s life (through the seeds, roots, stems and leaves). Similar to other plants, the Boswellia species have also been found to harbour endophytic microbes. Various species such as endophytic fungi (Chaetomium sp., Preussia sp., Penicillium, Thielavia, Phoma sp., Aureobasidium sp., Dothideomycetes sp., Sordariomycetes sp. and Fusarium proliferatum) and bacteria (Bacillus, Rhizobium and Paenibacillus) have been reported to date. Some of these species have been reported to produce auxin, exozymes and secondary enzyme inhibitory metabolites. There are only a few studies on these subjects, and they are primarily on B. sacra, and thus further study on other economically important species such as B. papyrifera and B. serrata is needed. This future work will help researchers to not only understand the role of associated microorganisms but also understand the tree of life and evolution.
