Genes with putative roles in extracellular matrix regulation (GO analysis), altered expression in bp mutants [36] or having a BLR consensus binding site in the promoter ( http://arabidopsis.med.ohio-state.edu/AtcisDB/ webcite) are shown.

1Role, or putative role in modification of the extracellular matrix.

2Reduced expression in bp compared to wild-type plants (Mele et al., 2003).

3Increased expression in bp compared to wild-type plants (Mele et al., 2003).

4BLR DNA binding consensus sequence present in promoter.

Expression values are presented as the mean ± standard error for three biological replicates.
