<p>(A) E-value distribution of the top BLAST hits for each unigene with a cut-off E-value of 1.0E-5. (B) Similarity distribution of the best BLAST hits for each unigene. (C) Species distribution is shown as the percentage of the total homologous sequences with an E-value of at least 1.0E-5. We used all plant proteins in the NCBI NR database for homology search and extracted the first hit of each sequence for analysis.</p
