Genetic material is in flux: this is one of the most exciting
recent concepts in molecular biology. This volume of "Plant Gene
Research" describes changes that occur in the genetic material of
plants. It is worthwhile re membering that the first examples of
unstable genomes were described for maize before DNA was known to
be the genetic material. Now trans posable elements like the ones
found in maize have been described in almost all organisms and have
become incorporated into our thinking about genome structure. Flux
in the plant genome is not restricted to transposable elements or
to nuclear genes. Exchanges of genetic material have been
demonstrated within organelle DNA, between organelle DNAs or
between organelle and nuclear DNAs. Such exchanges may only occur
over evolutionary times or may be a continuing process. Also the
environment alters the plant genome. Stress, either viral, nutri
tional or tissue-culture induced causes heritable changes in the
genome. Infection with the crown gall bacterium Agrobacterium
tumefaciens results in the transfer of bacterial DNA into the plant
genome."
