A Auxin synthesis by endophytes with and without tryptophan induction. Out of a total of 11 fungal endophytic isolates, eight produced IAA in the presence of tryptophan induction broth. B Out of a total of 11 fungal endophytic isolates, the three species were selected and their corresponding isolates were subjected to repeated IAA quantification. Values with different letters are significantly different at p ≤ 0.05 (Tukey test), C chromatogram of standard IAA as control and D Arrow indicate IAA detection peak in DLCCR7 broth
