Researchers have searched the wide variety of proteins that
Arabidopsis makes, and matched many of the proteins to the genes that code
for them, assembling a so-called ?proteome? map to compare with the genome
sequence.
Although the genome contains the basic instructions for building the
proteins, a variety of regulatory processes influence how the genome is
translated into the proteome.

Katja Baerenfaller and colleagues have now mapped out and analyzed the
Arabidopsis proteome and compared it to what the genome predicts. Many of
the identified proteins matched what was predicted from the genome, but some
were surprises, not otherwise predicted from the genome.


Further analysis of different organs and developmental stages also
shed light on how the proteome changes with development.
