Functional classification of ESTs identified by suppression subtractive hybridization. Numerical values represent a number of contigs from the forward subtraction library (FSL) and the reverse subtraction library (RSL) classified into each functional category. When EST clones confirmed or predicted by their nucleotide sequences to be derived from the same gene that gave other EST clones, they were counted as one gene. Classification mainly followed MIPS Funcat annotation.
