Genetic Engineering in Relation to Wood Production
· The subject of generic engineering or modification of living organisms has
generated considerable debate
· Generic engineering can be used to change the properties of the wood that
is produced
· Nowadays, greater demands are put on the timber industry, for example:
more and more homes are being built and in those new buildings, wood is
required for roof timber and trusses
· Timber is being used at an ever increasing rate and, as the UK has only a
limited managed forested area, much of that timber is being imported…read more

Genetic Engineering in Relation to Wood Production
· Biotechnology is at the forefront of research and experimentation
· Trials have been undertaken to genetically modify trees to increase the
amount of timber being produced
· Generically modified trees are the result of gene manipulation ­ this
involves artificially inserting a gene from one plant into the other, changing
the biological characteristics.
· Used in:
· UK (Scotland)
· Chile
· China
· Indonesia…read more

Genetic Engineering in Relation to Wood Production
Advantages: Disadvantages:
· Aids resistance of trees to disease · Long term side effects not yet
· Produces trees with increased growth apparent
rate · `Escape' of modified genes into
· Better forest management, which natural ecosystems
reduces deforestation · Development of tolerance to modified
· High quality timber trait by insect or/and disease
· Provide specifically coloured timbers organisms
· Rapid growth could cause shorter,
more intensive rotations, resulting in
greater water demand and reduced
opportunity for nutrient recycling…read more
