General description of libraries. (A) Table of ESTs and Unigene numbers presented for each library. The percentages of mitochondrial and rRNA sequences are also provided. (B) Distribution of unigenes (UGs) as a function of the number of ESTs involved in the UG sequences. UGs with only one EST are singletons, UGs with more than one EST are contigs. (C) Blast2go annotation results. Number of sequences presenting GO terms association is given for each step of the functional annotation. The different steps are described in the Methods section.
