First complete plastomes of the emblematic Andean tree genus Polylepis Ruiz & Pav. (Rosaceae).

ABSTRACT: Plastome genomics and phylogenomics are essential tools for understanding plant diversity and evolution. Here we report the complete plastomes of Polylepis australis and P. microphylla, two species of the Andean tree genus Polylepis which forms the world's highest treelines, using a whole-genome sequencing approach. The assembled plastomes (ca. 155 kb) exhibit the typical quadripartite structure of angiosperms with highly conserved gene content and organization. A total of 117 unique genes (81 protein-coding, 32 tRNA, and 4 rRNA) were annotated in the assembled plastomes. Comparative analysis revealed significant differences from previously reported partial plastomes of Polylepis, which lacked one copy of the inverted repeat (IR) region due to the limitations of long-range PCR methods.
