Comparison of the number of proteins annotated as 'expressed protein', 'hypothetical protein' or 'unknown protein' in the list of plant-specific proteins, proteins conserved throughout the phylogeny and in the whole Arabidopsis proteome. Total number of protein sequences per category (percentage relative to the total in the class) are shown. *Although the Arabidopsis TIGR genome release v3.0 (2002) was used to make the classification (plant-specific or other groups) and for all the other data analysis in this study, the numbers in this table reflect the latest protein annotation available from TIGR (genome release v4.0, April 2003). | |||
