Volumes I and 2 of this Plant Biotechnology series reviewed fundamental
aspects of plant molecular biology and discussed production and analysis
of the first generation of transgenic plants of potential use in
agriculture and horticulture. These included plants resistant to
insects, viruses and herbicides, which were produced by adding genes
from other organisms. Realisation of the potential of plant breeding has
led to a resurgence of interest in methods of altering the structure,
composition and function of plant constituents, which represents an even
greater challenge and offers scope for improving the quality of a wide
range of agricultural products. This, in tum, has resulted in a
re-evaluation of priorities and targets by industry. Volume 3 of this
series considers the biochemical and gentic basis of the biosynthesis of
plant products such as starch, lipids, carotenoids and cell walls, and
evaluates the ways in which biosynthesis of these products can be
modified for use in the food industries. Authors also cover the
biosynthesis of rare secondary products and the function and application
of proteins for plant protection and therapeutic use. The emphasis
throughout is on the relationship between fundamen- tal aspects of
biosynthesis and structure-function relationships, and application of
this knowledge to the redesigning and altering of plant products by
molecular genetics.
