Many plant genes are expressed in a highly regulated manner. Gene products may be present only in certain cell types, at specific stages of development or 0066-4294/87/0601-0221$02.00 KUHLEMEIER, GREEN & CHUA only following the application of distinct environmental stimuli. A specific gene can be turned on by very different inducers, or a single stimulus may have totally different effects on different genes. Gene cloning coupled with efficient systems for gene transfer has made it increasingly possible to unravel the complexity of plant gene regulation. Initial gene transfer experiments primarily made use of undifferentiated calli. With these systems it was demonstrated that foreign genes could be introduced into a plant genome and faithfully expressed: that is, the mRNAs had the cognate 5' and 3' termini, were spliced correctly, and in some cases gave rise to protein products. Gene regulation could be studied to a limited extent. Further development of gene transfer technologies allowed for the introduction of genes into cells that retained the capacity to differentiate. From these cells, fertile plants could be regenerated that contained a foreign gene in all cells. Such transgenic plants provide a much better background for studying gene regulation in its full complexity. In
