Abstract

The chloroplast genome of the Araucaria cunninghamii has been completely sequenced. The genome size is 146,337 bp, and the overall GC content is 36.7%. This cp genome does not contain cannonical IRs, it encodes a total 122 genes including 82 protein-coding genes, 36 tRNA genes and four rRNA genes. Among them, eight protein-coding genes (rpl2, rpl16, petB, petD, rpoC1, atpF, ndhA and ndhB) have two exon, and two genes (rps12 and ycf3) have three exons. Also, trnI-CAU and rrn5 has two copies. The Maximum-likelihood tree shows that A. cunninghamii is sister to A. heterophylla.

Keywords: Araucaria cunninghamii; chloroplast genome; phylogenetic analysis.
