The present project focuses on the isolation and characterization of melatonin-producing endophytic bacteria from selected medicinal plants. Endophytic bacteria are beneficial microorganisms that reside within healthy plant tissues without causing any apparent harm to the host. Recent studies suggest that certain endophytes are capable of synthesizing melatonin, a biologically important indoleamine involved in growth regulation, stress tolerance, and circadian rhythm modulation in plants.
Medicinal plants are considered rich reservoirs of diverse endophytic microbial communities due to their unique secondary metabolites and adaptive ecological niches. By exploring these endophytes, the study aims to identify bacterial strains with the ability to produce melatonin and evaluate their potential applications in agriculture, biotechnology, and health-related research.
To isolate endophytic bacteria from roots, stems, and leaves of selected medicinal plants
To screen the isolated endophytic bacteria for melatonin production
To characterize melatonin-producing bacterial isolates using biochemical and molecular methods
To assess the potential role of these endophytes in plant growth promotion and stress tolerance
To explore the applicability of melatonin-producing endophytes in agricultural and biotechnological interventions
Selection of Medicinal Plants: Healthy medicinal plants will be selected based on ethnobotanical importance.
Surface Sterilization: Plant tissues (roots, stems, leaves) will be surface-sterilized to eliminate epiphytic microorganisms.
Isolation of Endophytic Bacteria: Sterilized tissues will be cultured on appropriate growth media using standard microbiological techniques.
Screening for Melatonin Production: Isolates will be screened using biochemical assays and analytical techniques such as chromatography-based methods.
Characterization of Isolates: Selected melatonin-producing strains will be characterized through morphological, biochemical, and molecular analyses.
Data Analysis: Comparative analysis will be performed to correlate melatonin production with bacterial diversity and plant source.
Identification of melatonin-producing endophytic bacterial strains from medicinal plants
Establishment of a microbial repository of potential bioactive endophytes
Better understanding of the role of endophytic bacteria in melatonin-mediated plant functions
Generation of baseline data for further functional and application-oriented studies
This study provides valuable insights into the plant–microbe interaction involving melatonin synthesis and regulation. The identification of melatonin-producing endophytic bacteria opens new avenues for the development of eco-friendly bioinoculants that can enhance plant growth, stress tolerance, and productivity. Additionally, these endophytes may serve as promising resources for biotechnological and pharmaceutical research, contributing to sustainable agriculture and health-related innovations.
