| dc.description.abstract | Lagenandra toxicaria is a medicinal aquatic plant that harbors a diverse array of
endophytes with promising applications. This study delved into the endophytic
community, their interactions, and their potential for producing phytochemicals,
exhibiting antimicrobial and antioxidant activities, producing enzymes, and
promoting plant growth. The research successfully identified the diverse range of
endophytes present in each plant part, location, and season, revealing that their
diversity varies depending on the season and plant part. Multivariate ANOVA
analysis showed that seasonal changes and plant parts influence diversity of
endophytes. Notably, a fungal isolate exhibited potent antibiotic activity due to a
compound with antimicrobial properties. The potent isolates were found to contain
significant amounts of flavonoid, phenol, terpenoid, coumarin, quinone, and
glycoside. Fungal isolates from leaves demonstrated antimicrobial and antioxidant
activities, while bacterial endophytes were identified as efficient producers of
enzymes, particularly protease.
Both fungal and bacterial endophytes exhibited plant growth-promoting
properties, including producing indole-3-acetic acid, solubilizing phosphate, and
exhibiting ACC deaminase activity. Experimental studies confirmed the quality
and stability of enzymes and the effect of IAA on seedling development. HPLC
analysis identified the production of IAA and DEP by corresponding isolates under
pre-optimized and optimized conditions. This study highlights the vast potential
of Lagenandra toxicaria endophytes for sustainable agriculture, biotechnology,
and environmental remediation. Further optimization of endophyte-plant
interactions and bioactive compound production can unlock new opportunities for
eco-friendly solutions. The research contributes to the understanding of
endophyte-plant interactions. It emphasizes the importance of exploring
Lagenandra toxicaria endophytes for future applications, demonstrating their
potential for sustainable agriculture, biotechnology, and environmental
sustainability. | en_US |
