%X Euphorbia, one of the largest genera of flowering plants, is well-known for containing many biofuel crops. Euphorbia tirucalli, an evergreen succulent mainly native to the Africa continent but cultivated worldwide, is a promising petroleum plant with high tolerance to drought and salt stress. However, the exploration of such an important plant resource is severely hampered by the lack of a reference genome. Here, we present the chromosome-level genome assembly of E. tirucalli using PacBio HiFi sequencing and Hi-C technology. Its genome size was approximately 745.62 Mb, with a contig N50 of 74.16 Mb. A total of 743.63 Mb (99.73%) of the assembled sequences were anchored to 10 chromosomes with a complete BUSCO score of 97.80%. Genome annotation revealed 26,304 protein-coding genes, and 76.37% of the genome was identified as repeat elements. The high-quality genome provides valuable genetic resources that would be useful for unraveling the genetic mechanisms of biofuel synthesis and evolutionary adaptation of E. tirucalli.
