摘要：
The in situ analysis presented here indicates that polyhomeotic transcripts are expressed in a spatially restricted fashion early in development. This blastoderm expression is under the control of genes in the segmentation hierarchy. Given these results, and the role of polyhomeotic in the correct maintenance of homeotic gene expression, I propose that polyhome otic expression may relay the initiation of homeotic gene expression with other mechanisms involved in the maintenance of this expression, involving the other Pc -group genes. 1992 Wiley-Liss, Inc.
