Distribution of sequence length (bp) of consensus sequences (TCs) and singletons that constitute the apple unigene set.

Distribution of apple unigenes whose putative functions could be assigned through annotation. Role categories according to gene ontology (Gene Ontology Consortium, 2001) were derived from BLASTX matches of apple unigenes against the annotated Arabidopsis proteome and are as follows: (A) Distribution of annotated apple unigene set to three GO functional groups; (B) molecular function; (C) biological process; (D) cell component.

Distribution of conservation between apple unigenes and genes in the Arabidopsis genome based on tBLASTX scores. Tentative contigs and singletons for whole apple unigene set. E ≥0.1, apple sequences with no match to Arabidopsis; E <1.0 ×10−50, “slow-evolving” genes; E ≤1.0 × 10−15 to E ≥1.0 × 10−50, “intermediate-evolving” genes; E >1.0 × 10−15, “fast-evolving” genes. (A) All apple unique sequences. (B) Only those apple sequences for which putative function could be established through annotation.

Distribution of conservation between apple unique sequences and citrus and poplar genes based on tBLASTX scores. (A) Distribution of all apple sequences that had a match in citrus–poplar database. E <1.0 × 10−50, “slow-evolving” genes; E ≤1.0 × 10−15 to E ≥1.0 × 10−50, “intermediate-evolving” genes; E >1.0 × 10−15, “fast-evolving” genes. (B) Only those apple sequences with citrus–poplar but no Arabidopsis match. E <1.0 × 10−20, “slow-evolving” genes; E >1.0 × 10−20, “fast-evolving” genes.

Distribution of conservation between apple sequences and citrus and poplar genes based on tBLASTX scores. E <1.0 × 10−50, “slow-evolving” genes; E ≤1.0 × 10−15 to E ≥1.0 × 10−50, “intermediate-evolving” genes; E >1.0 × 10−15, “fast-evolving” genes. AC, apple–citrus comparison; AP, apple–poplar comparison.
