The plant P450 database has been updated (see the Databases button on the home page). Plants now have over 400known P450s. 212 are from Arabidopsis. The Deep Green meeting in St. Louis described in todays Science has found that plants should be split into three kingdoms not just one. Green, brown and red plants split at about the same time from a common ancestor. Each of these divisions should be accorded kingdom status. This is different from the usual view, and it will be interesting to see how this sorts out. I will be interested to know which P450s are specific to each clade, and which predate the split.
