Complete plastome sequence of endangered timber species Dipterocarpus tempehes Slooten

Abstract

Dipterocarpus tempehes is an endangered tropical timber tree species endemic to Borneo. In this study, the plastome of D. tempehes was assembled. The whole chloroplast genome was 145,323 bp in length, with a large single-copy (LSC) region of 80,375 bp and small single-copy (SSC) region of 20,394 bp, separated by two inverted repeats (IRs) regions of 22,277 bp. It contained 145 genes, including 102 coding genes, 35 tRNA genes, and 8 rRNA genes. A phylogenomic analysis confirmed that Malvaceae s.l., Thymelaeaceae, and Dipterocarpaceae formed its respective monophyletic clade, with D. tempehes forming a sister clade with species from the Shoraeae tribe within the family.
