Endophytes from medicinal plants and their potential for producing indole acetic acid, improving seed germination and mitigating oxidative stress

Abstract Background Himalayan yew (Taxus wallichiana) is one of the endangered medicinal plants species having great importance due to the presence of anticancer drug Taxol. This metabolite is mainly used for the treatment of ovarian, breast, AIDS-related cancers, and other indications. The study being reported here was conducted for the propagation of Himalayan yew by using two different trials of Indole Butyric acid (IBA) and Indole acetic acid (IAA) hormones treatments (2000–7000 ppm) through stem cuttings (140 each). In the same way, 3840 cuttings were treated with IBA and IAA from November 2016 to November 2017 at Lalku valley, Swat, Khyber Pakhtunkhwa (KP), Pakistan. Results The influence of IBA treatment (7000 ppm) showed a survival of 85.22% (average number of roots = 10.4, average length of roots = 15.5 cm, average number of leaves = 92.4 and average number of sprouts = 3.3) while that of IAA treatment (7000 ppm) the survival of 81.11% (average number of roots = 9.1, average length of roots = 14.6 cm, average number of leaves = 84.0 and average number of sprout = 3.0) were more significant followed by 2000–6000 ppm (IBA and IAA). Lowest survival 40–45% (average number of roots = 4.2, average length of roots = 8.0 cm, average number of leaves = 32.2, average number of sprouts = 1.7) was noticed for controlled cuttings. Conclusion The present study enhanced the potential of conservation and propagation of T. wallichiana. Hence our study suggests and recommends the application of IBA (7000 ppm) as a better hormone for the conservation and propagation of Himalayan yew.

Biomass Increase

The use of microorganisms in medicinal plants may provide an increase in biomass. The objective of this work was to evaluate the efficiency and capacity of Trichoderma strains to solubilize phosphate and to synthesize indole acetic acid (IAA) in vitro in the biomass production of two medicinal plants, basil and mint. Cultures were inoculated with two species of Trichoderma. The crop biomass as well as the relative efficiency were determined. Trichoderma species that solubilized phosphate and produced IAA, provided significant results in the accumulation of biomass of the crops, with relative efficiency of 276% for mint and 141% for basil, in relation to the control. The Trichoderma isolates showed phosphate solubilization capacity and IAA synthesis. Therefore, the studied crops presented biomass increase. These strains verified their capacity as plant growth promoters.

And Control

Effect of plant growth regulators on seed germination and seedling characters in terms of root length and shoot length. The seeds of sesame variety TVM – 1 were treated with different concentration of gibberlic acid (1.0, 2.0, 3.0 and 4.0 mg/l) and indole acetic acid (1.0, 2.0, 3.0 and 4.0 mg/l). From the results, it was observed that the GA3 and IAA at 2.0mg/l had regulatory effect on seed germination and seedling characters. Maximum germination, root length and shoot length was observed at 2.0mg/l in GA3 and 2.0mg/l in IAA than control. And GA3 at 2.0gm/l was found to be more efficient to modify seed germination and seedling characters when compared to IAA and control.
