Hypothesis
Can endophytic fungi enhance plant growth through the production of gibberellins?
Conclusion
The newly isolated strain of Penicillium citrinum shows significant potential for promoting plant growth and could aid in the conservation of coastal sand dune flora.
Supporting Evidence
- Fifteen endophytic fungi were isolated from the roots of Ixeris repenes.
- The fungal isolate IR-3-3 promoted maximum plant growth in rice and Atriplex gemelinii seedlings.
- IR-3-3 produced higher levels of physiologically active gibberellins compared to the control strain G. fujikuroi.
- GA5, a precursor of bioactive GA3, was reported for the first time in fungi.
Takeaway
Some fungi can help plants grow better by making special chemicals. This study found a new type of fungus that does just that!
Methodology
Fungal isolates were screened for growth-promoting metabolites using culture filtrates applied to rice and Atriplex gemelinii seedlings.
Limitations
The study focused only on a specific environment and plant species, which may limit the generalizability of the findings.
