大戟科包括一些最有效的生物质植物。这些物种的全基因组测序和遗传图谱的开发是分子育种和遗传改良的重要组成部分。在这里，我们报告了麻风树（Jatropha curcas L.）的基因组草图，一家生物柴油厂组装的基因组全长320.5 Mbp，包含27，172个推定的蛋白质编码基因。我们建立了一个包含1208个标记的连锁图谱，并将基因组组装（81.7%）锚定到该图谱上，产生11条假染色体。经过基因家族聚类，共鉴定出15,268个家族，其中13,887个存在于蓖麻基因组中。对基因组的分析突出了该物种进化过程中一些基因家族的特异性扩张和收缩，包括核糖体失活蛋白和油生物合成途径酶。该基因组序列和连锁图谱不仅为大戟的基础和应用研究提供了宝贵的资源，而且为进化和比较基因组学分析提供了宝贵的资源，特别是在大戟科。
The family Euphorbiaceae includes some of the most efficient biomass accumulators. Whole genome sequencing and the development of genetic maps of these species are important components in molecular breeding and genetic improvement. Here we report the draft genome of physic nut (Jatropha curcas L.), a biodiesel plant. The assembled genome has a total length of 320.5 Mbp and contains 27,172 putative protein-coding genes. We established a linkage map containing 1208 markers and anchored the genome assembly (81.7%) to this map to produce 11 pseudochromosomes. After gene family clustering, 15,268 families were identified, of which 13,887 existed in the castor bean genome. Analysis of the genome highlighted specific expansion and contraction of a number of gene families during the evolution of this species, including the ribosome-inactivating proteins and oil biosynthesis pathway enzymes. The genomic sequence and linkage map provide a valuable resource not only for fundamental and applied research on physic nut but also for evolutionary and comparative genomics analysis, particularly in the Euphorbiaceae.
