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.
