In reply to Mark Estelle's question:
>Can anyone suggest a source for Arabidopsis codon usage information. 

I created a codon usage table for Arabidopsis using GenBank 63. The codon 
usage table included below and tables for 46 other organisms can be 
retrieved via anonymous ftp from frodo.mgh.harvard.edu, 
ftp.bio.indiana.edu, and ftp.bchs.uh.edu. The tables are also available on 
the EMBL mail server and others.

I hope to update these tables in the next month or two with sequences from 
GenBank 71.

Arabidopsis thaliana

31 genes found in GenBank 63.

 Produced by J. Michael Cherry (cherry at frodo.mgh.harvard.edu) with the
 GCG program CodonFrequency.

 Duplicates, pseudogenes, mutant and synthetic genes were not included.
 Coding regions were specified using the Feature Table of each entry, then
 checked for accuracy. If more than one stop codon was found the sequence
 was not included.
