Ng, Kobayashi, et al. present the genome assembly for the dipterocarp Shorea leprosula and present transcriptome data for ten more dipterocarp species of seven genera. The Shorea leprosula genome, along with drought stress experiments, demonstrate evidence for a whole-genome duplication (WGD) event dated to the Cretaceous-Paleogene boundary, with WGD duplicates enriched in genes upregulated during the drought response.
