had different exon and intron structures. The proteins
encoded by these OsMAX1 genes belonged to the
CYP711 protein family. In addition, there is a very
high homology in the amino acid sequences of MAX1
(Supplemental Fig. 2). Through protein cluster analysis,
we discovered that the P450 proteins encoded by MAX1
genes widely existed in monocot and dicotyledonous
plants, and there were lots of conserved branches in
monocot plants.
