Lessons learned from sesquiterpene synthesis:
Implications to genetic engineering of secondary metabolism in plants
ACS National Meeting, Anaheim, CA, March 22, 1999.
Abstract (Paper 22)::
We have been studying the regulation and control of the sesquiterpene
phytoalexin pathway as a model for understanding secondary metabolite production in
plants.
This pathway is:
induced by fungal elicitors, coordinately regulated with
competing pathways, product feedback inhibited and controlled by a complex
interaction of signal transduction messengers.
Most recently we have fused the promoter
of the inducible branch-point enzyme sesquiterpene cyclase to the GUS and green
fluorescent protein (GFP) reporter genes to understand spatial localization of gene
regulation.
The general implications of these studies to genetic engineering of secondary
metabolism in plants will be discussed.
