Potential of endophytic fungus Aspergillus terreus as potent plant growth promoter

摘要

Fungal endophytes are well-noted residents inside plant tissues to assist plant development and fitness. However, plant growth-promoting endophytes (PGPE) are less reported therefore, the objectives of present study were to isolate fungal endophytes, identify and illustrate their potential for plant growth-promotion. Endophyte Aspergillus terreus was selected to check its role in promoting growth of tomato seedlings. The isolate showed positive results for hydrogen cyanide and indole acetic acid (IAA) production, phenols and flavonoids production under In vitro conditions. Endophyte associated tomato seedlings showed higher growth than the control. The results showed that isolated and characterized microbial endophytehad a considerable impact on plant growth parameters and could be helpful as inoculants to improve a sustainable farming system without posing any adverse effect on environment.
