Assignment of EST fragments by functional category and the percent representation of each category in the collection of the O. novo-ulmi yeast LMW library.
¹Based upon the MIPS classification scheme for the functional annotation of protein sequences [50].
²Classification of known yeast LMW sequences, as determined by BLASTX searches and homology to sequences of known identity.
³Relative percentage of known yeast LMW sequences in each functional category.
