Comparison of mRNA and protein expression data: gap domain boundary positions.

This table shows mRNA (grey rows) and protein (white rows) boundary locations through developmental time in percent A—P position (where 0% is the anterior pole). A: indicates anterior, P: posterior boundary of a domain. T1—8 indicate time classes subdividing C14A. Boundary positions for mRNA domains correspond to the starting points of approximating splines as described in Materials and Methods. Boundary positions for protein domains are taken from [43], and correspond to the position where the level of gene expression reaches a threshold of 50% maximum fluorescence intensity. Single dashes indicate boundaries that are not present at a give time point. Double dashes indicate boundaries that are observable, but were not measured in [43].
