Many important food and fibre crops have attained close to their maxim
um yields as a result of conventional breeding approaches and advances
in agronomic and horticultural practices. The manipulation of cell an
d tissue cultures to produce somatic embryos efficiently is one of the
keystones of the new technologies that will greatly alter the way cro
ps are planted (as synthetic seed) and genetically altered in the futu
re. Gene transfer into embryogenic plant cells is already challenging
conventional plant breeding, and has become an indispensable tool for
crop improvement, This review provides a current assessment of the imp
act of somatic embryogenesis in agriculture.
