The dif￾ferences expression levels between typeI and typeII genes in the Chinese cabbage tissues were consistent with that in Arabidopsis (Kofuji et al. 2003). In Chinese cabbage the well-known ABCDE model genes have high expression levels in flowers, except BrMADS046, 052, 057, which only have high expression levels in roots. The CDE genes that are not only in flowers but also in siliques have higher expression levels.
