The plastome sequence of Laurus azorica (Seub.) Franco, an endemic tree species of the Azores islands

Abstract

Laurus azorica is an endemic tree species from Azores archipelago. In this study, we generated the plastome sequence as a first step in a global assessment of island endemic Lauraceae. The total chloroplast genome was 153,061 bp in length, with a large single copy (LSC) region of 87,226 bp and a small single copy (SSC) region of 18,033 bp, separated by two inverted repeats (IRs) regions of 23,901 bp. The overall GC content was 37.3%, and 43.1%, 35.4%, and 31.1% in the IRs, LSC, and SSC regions, respectively. It contained 106 genes, including 79 coding genes, 24 tRNA genes, and four rRNA genes. A phylogenetic analysis confirmed that L. azorica was clustered with L. nobilis within the family Lauraceae.
