The growth response of roots to stress conditions is a strategy that allows the plant to either avoid the adverse conditions or to adapt to them. H an activities have resulted in the accumulation of some metals from certain concentrations have an adverse effect on plant growth. Among these, Chromiumumm (Cr) is a serious pollution caused by metal processing industries and leather tanning. To understand in detail the response of roots Cr(VI) stress, it was used an in vitro system with Arabidopsis thaliana utilizing three experimental conditions. (A) Plants germinated and grown for 6 days, without lateral roots, were transferred to media with different concentrations of Cr(VI). This allowed the evaluation as affecting the growth of the primary root to move... |

Abstract: This study evaluates the antibacterial, cytotoxic activities, and phytochemical composition, of Callistemon citrinus, Hibiscus rosa-sinensis and Plumbago auriculata leaves and flowers, three ornamental plants in Mexico. However, in other countries offers a range of other uses. Ethanol extracts of C. citrinus leaf and flower presented stronger antibacterial activity than the extracts obtained from the other two plants. C. citrinus leaf showed low cytotoxicity (LC50 <600 µg/mL) on the brine shrimp test, whereas the ethanol extracts of H. rosa-sinensis and P. auriculata leaves showed no cytotoxic activity. Flower extracts obtained from the three plants did no exhibit cytotoxicity. GC-MS analysis revealed that the ethanol extract of P. auriculata... |
