Table 2. Comparison of numbers of ESTs in public databases for plant enzymes involved in fatty acid and lipid metabolism as of August, 1999. The same data are presented in histograms 1-4.Proteins encoded by gene families are marked with asterisks. For numbers of ESTs of individual genes in Arabidopsis and rice see multiple alignment files.
