Abstract:
|
Plant cell cultures constitute a promise for the production of a high number of phytochemicals, although the majority ofbioprocesses that have been developed so far have not resultedcommercially successful. An overview indicates that most of theresearch carried out until now is of the empirical type. For this reason,there is a need for a rational approach to the molecular and cellularbasis of metabolic pathways and their regulation in order to stimulatefuture advances.The empirical investigations are based on the optimization of theculture system, exclusively considering input factors such as theselection of cellular lines, type and parameters of culture, bioreactordesign and elicitor addition, and output factors such as cellular growth,the uptake system of nutrients, production and yield. In a rationalapproach towards the elucidation of taxol and related taxaneproduction, our group has studied the relationship between the taxaneprofile and production and the expression of genes codifying forenzymes that participate in early, intermediate and late steps of theirbiosynthesis in elicited Taxus spp cell cultures. Our results show that elicitors induce a dramatic reprogramming of gene expression in Taxus cell cultures, whichlikely accounts for the enhanced production of taxol and related taxanes and we have alsodetermined some genes that control the main flux limiting steps. The application ofmetabolic engineering techniques for the production of taxol and taxanes of interest is also discussed. |
