NB:  Textbook Heldt 3rd edition page numbers will be slightly different

 

* Reading summaries due date. These will be assigned at least one week before.

** Term paper/bibliography due dates

 

 

TEXTBOOK: none required. Optional textbook (Heldt, "Plant Biochemistry", 3rd or 4th edition)  will be on reserve at the library and should be consulted to reinforce lectures. Some material is covered by Taiz and Zeiger's "Plant Physiology", also on Reserve. Readings from the primary literature will be assigned every other week (5 in total). You will be asked to do very brief summaries of these readings, to be handed in and discussed in class.

 

COURSE OBJECTIVES:

To provide an introduction to plant chemicals, their role in the plant and ecosystem, and the biochemical basis of plant adaptation. Emphasis will be on plant-specific biochemical pathways and processes, and their regulation and molecular biology. Topics include: storage carbohydrates, cell wall biosynthesis, lipid metabolism, nitrogen fixation and assimilation; biochemistry and ecology of secondary plant metabolites such as isoprenoids, phenolics and alkaloids, and their roles in plant-animal and plant-environment interactions.

 

WEB-ACCESSIBLE / ADDITIONAL MATERIAL:

Lecture materials will available be prior to the lecture (see http://web.uvic.ca/~cpc/). Please be aware that these are abbreviated notes. It is therefore imperative that you attend lectures.
