  1. The GO assignments for A. thaliana ESTs were obtained from TIGR [38]. The percentage of GO assignments for A. thaliana was calculated based on the total numbers of GO mappings in each of the three major ontologies with the number of unknown terms deducted from them (biological process: 20185, molecular function: 23680, cellular component: 6309). The functional categories present in A. thaliana but not in S. moellendorffii were not listed in the table.
