RANSLATIONAL C ONTROL Translation is a potential step in the regulation of gene expression. However, this stage is less well understood than the control of transcription. For example, some plant viral RNAs are more efficiently translated than the endogenous host mRNAs and this enhancement is due to the presence of translational enhancers in the 5¢ leader sequence. S UMMARY An overall view of the regulation of transcription should ultimately emerge from the whole genome analysis that can be performed in Arabidopsis and rice with the complete genome sequence. From these analyses the cis-acting elements that are necessary for the ultimate control of gene expression will become apparent, as well as the characterization and understanding of all interactions between transcription factors, other proteins, and the cis-acting elements. As with all of the genome-wide studies, large amounts of data will need to be correlated and integrated in order for the overall picture to become clearer. R EFERENCES Ali, S., and W. C.
