title: Leaves of mature Cladrastis Yungchunii
design: DNA samples were stored at the Key Laboratory for Forest Resources Conservation and Utilisation in the Southwest Mountains of China Ministry of Education, Southwest Forestry University, Kunming, China. The total genomic DNA was extracted by using the Magnetic beads plant genomic DNA preps Kit (TSINGKE Biological Technology, Beijing, China). The genome skimming sequencing was conducted on the Illumina HiSeq 2000 Sequencing platform. Genome annotation was assembled with the program Geneious R8 (Biomatters Ltd, Auckland, New Zealand).
