Abstract
The complete chloroplast genome of Juniperus cedrus is a circular molecule of 127 126 bp in length with 115 single copy genes and two duplicated genes (trnI-CAU and trnQ-UUG). The genome contains 82 protein-coding genes, four ribosomal RNA genes and 33 transfer RNA genes. In these genes, eight genes (rpl16, rpl2, rpoC1, petD, petB, ndhB, ndhA and atpF) harbor a single intron and two genes (rps12 and ycf3) harbor two introns. Like other sequenced chloroplast genomes of conifers, this genome does not contain canonical inverted repeats (IRs), and the overall GC content of J. cedrus chloroplast DNA is 35%. The phylogenetic analysis revealed that J. cedrus is more closely related to J. scopulorum and J. bermudiana.
