This chapter contains sections titled: Introduction The current theory Is there a need for a new theory? Are criticisms of the current theory valid? Is there anything wrong with the dirigent hypothesis? Why the new hypothesis is not in contention Is lignification a biochemical anomaly? Summary comments on the dirigent/replication hypothesis Conclusions Notes References
