The complete chloroplast genome of Bursera paradoxa , a unique species endemic to Mexico

Bursera paradoxa is an endemic tree native to Mexico, with high economic and ecological value but little research. The complete chloroplast genome of B. paradoxa is reported for the first time. It is 159,851 bp in length and displays a typical quadripartite structure, including a large single-copy region (87,441 bp), two inverted repeat regions (26,810 bp), and a small single-copy (18,790 bp) region. The genome encodes 133 genes, comprising 87 protein-coding genes, 36 tRNA genes, and 10 rRNA genes, showing a similar structure to B. fagaroides. A total of 35 SSRs are detected in the genome, ranging from 10 bp to 108 bp in length and varying from 6 to 17 in number of repeats. Most of these SSRs are located in single-copy regions and rarely in inverted repeat regions. Phylogenetic analysis supports the monophyly of Bursera and places B. paradoxa as sister to B. fagaroides.
