I have just analyzed 163 Arabidopsis expressed sequence tags found in the ESTdb. These have all been translated and aligned with the other plant P450s in a new plant only alignment of 125 public sequences. 39 confidential sequences have been removed from a comprehensive 165 plant sequence alignment. Some interesting features are noted. A CYP72 sequence has been assembled from Arabidopsis ESTs. Two EST fragments are CYP51 sequences for lanosterol 14 demethylase, one is from Zea mays.
