Effect of fungal homogenate, enzyme inhibitors and osmotic stress on alkaloid content of Catharanthus roseus cell suspension cultures
1991
Godoy-Hernandez, G. | Loyola-Vargas, V.M.
The addition of Aspergillus niger homogenate to Catharanthus roseus cell suspension cultures produced an increment of more than 60% in the alkaloid content of two different cell lines. The use of an inhibitor of phenylalanine ammonia lyase, i.e. cinnamic acid, along with the homogenate, resulted in an appearance of 90% of the alkaloids in the medium. Furthermore, even in the absence of fungal homogenate, there was a marked increase in the alkaloid content. The exposure of the cells to an osmotic stress produced a marked increment (320%) in the total alkaloid content. When both stress treatments were applied sequentially, an additive effect on alkaloid accumulation was observed. It was 300% higher than in cells cultured without treatment, the majority of the alkaloids found in the medium.
