Independent integrants at the same locus show different spatial patterns of gus expression. All seedlings are stained for GUS activity at the two-leaf stage. At the 95 locus, the 95g line has a vascular specific expression characteristic of the Cp promoter (A,D). The 95q line shows sectoring of gus expression (B,E–I), and the 95o line rarely shows gus expression (C).
