Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The influence of methyl jasmonate (MeJA) and NaCl on a Catharanthus roseus suspension cell culture with high production of ajmalicine was investigated. Suspension cell cultures were treated with 100 mM NaCl or 100 μM MeJA or both for 3 d before harvesting, and measurements were then performed. NaCl treatment increased both the cell membrane permeability and ajmalicine accumulation. MeJA treatment promoted ajmalicine accumulation and maintained membrane permeability of cells under salt stress. However, a cumulative effect of both factors on the accumulation of ajmalicine was not found. Our results suggest that the higher ajmalicine accumulation in the medium after treatment with NaCl was associated with the cell membrane permeability.
