The table shows the distribution of classifications as a percentage of the total number of classifications.
a Apple genes for each EST on the array were used to identify Arabidopsis homologues using BLAST with a cutoff of 1 e-5. Where a putative homologue was identified, the Arabidopsis MIPS (Munich Information centre for Protein Sequences, funcat version 1.3) classification(s) for that gene were applied to the apple EST.
b For the whole array, for the features selected as changing during fruit development, and for each of the clusters and sub-clusters the frequency of occurrence for each functional category is shown as a percentage of the total number of functional categories for that cluster (or sub-cluster). FB = Full bloom; EFD = early fruit development; MD = mid-development; R = ripening; R1, R2, R3 = the 3 ripening sub-clusters; EFD1, EFD2 = the 2 early fruit development sub-clusters.
