Bacterial and fungal endophytes are widespread inhabitants inside plant tissues and have been shown to

assist plant growth and health. However, little is known about plant growth-promoting endophytes

(PGPE) of medicinal plants. Therefore, the aims of this study were to identify bacterial and fungal endophytes of Teucrium polium and to characterize plant growth-promoting (PGP) properties of these endophytes. Seven bacterial endophytes were isolated and identified as Bacillus cereus and Bacillus subtilis,

where five endophytic fungi were obtained and assigned to Penicillium chrysogenum and Penicillium crustosum. The isolated endophytes differentially produced indole acetic acid (IAA) and ammonia, and in

addition to their enzymatic and antimicrobial activities, they exhibited variable capacity for phosphate

solubilization. In order to investigate the effect of endophytes on plant growth, four representative endophytes and their consortiums were selected concerning to their potential ability to promote plant growth.

The results indicated that microbial endophytes isolated from medicinal plants possessing a vital role to

improve plant growth and could be used as inoculants to establish a sustainable crop production system.
