In vitro culture provide a suitable condition for regeneration of arsenic tolerant plants from stem calli of Andrographis paniculata (Burm.f.) Nees. The regenerated plants could be valuable material applicable to soil remediation. In vitro culture of stem explants on MS basal salts, 3.0% sucrose, 0.8% agar medium fortified with various concentrations of As2O3 (0.0-9.0 µM) along with NAA (3.5 mg L-1) and KIN (1.0 mg L-1) influenced resistant callus formation. Growth of callus was slightly inhibited with increased resistance up to 22% (53±0.8 mg fwt and 27±1.5 mg dwt) on 7.0 µM As2O3 selective medium. The resistant callus line inoculated on MS medium supplemented with different concentrations of As2O3 along with BA (2.5 mg L-1) and NAA (3.0 mg L-1) induced the development of shoots. Shoot organogenesis was slightly inhibited by arsenic metal stress. However the growth tolerance has increased up to 14.5% on medium with 7.0 µM As2O3. The rate of adventitious rooting of plantlets was gradually decreased with more tolerance (11.1±1.4 rootlets per plantlets) in 7.0 µM As2O3 selected media. After acclimatization, about 40% of plants were survived as arsenic tolerance than control plants in pots containing soil treated with 7.0 µM As2O3 solutions. The level of arsenic detectability was 0.96 ppb and 4.67 ppb in control and 7.0 µM As2O3 treated plants, respectively by AAS analysis. Moreover, the production of Andrographolide was found quite high (4.41 mg/g) in tolerant plants grown at 7.0 µM As2O3 treatment than control by HPLC analysis. 1D 1H NMR profile revealed the metabolic changes significantly in control and 7.0 µM As2O3 treated plant samples. This is the first report confirming the suitability of in vitro selection for obtaining of vigorous and proliferative clones of A. paniculata plants tolerant to elevated arsenic concentration.
