• Medicinal plants are known to harbor potential endophytic microbes, due to their bioactive compounds. In a first study of ongoing research, endophytic bacteria were isolated from two medicinal plants, and with contrasting antimicrobial activities from the Chatkal Biosphere Reserve of Uzbekistan, and their plant-specific traits involved in biocontrol and plant growth promotion were evaluated. Plant extracts of exhibited a remarkable activity against bacterial and fungal pathogens, whereas extracts of did not exhibit any potential antimicrobial activity. Matrix-assisted laser desorption ionization (MALDI) time-of-flight (TOF) mass spectrometry (MS) was used to identify plant associated culturable endophytic bacteria. The isolated culturable endophytes associated with belong to eight genera ( , and ). The endophytic isolates from also contain those genera except , , and . with antibacterial activity supported more bacteria with antagonistic activity, as compared to . The antagonistic isolates were able to control tomato root rot caused by and stimulated plant growth under greenhouse conditions and could thus be a cost-effective source for agro-based biological control agents.
