Abstract:Cinnamomum camphora (L.) Presl is a kind of precious wood species and the main no-timber trees of special local product in our country and possess abundant the secondary metabolism,such as polysaccharides, polyphenols, oleicacid and terpenoid. C. camphora is a metallic element used in many important industries. In this study, the genome size of C. camphora was determined by new-generation sequencing technologies (Illumina HiseqTM 2000). Hybridity percentage, repeats and GC_depth were also estimated by bioinformatics. The main results were showed as following: (1) The average genome size of C. camphora was about 760 Mb; (2) Hybridity percentage of C. camphora was about 0.65%; (3) Whole-genome shotgun sequencing was not used to C. camphora genome sequencing, and the BAC-to-BAC or fosmid could be used to it.
