Outcome of homology search of litchi unigenes against the nr database. (A) Venn diagram of unigene numbers annotated by BLASTx with an E-value threshold of 10−5 against protein databases. The numbers in the circles indicate unigenes numbers annotated by single or multiple databases. (B) E-value distribution of the top BLAST hits for each unique sequence. (C) Species distribution of the top BLAST hits for all homologous sequences.
