Jatropha curcas (physic nut), a non-edible oilseed crop, represents one of the most promising alternative energy sources due to its high seed oil content, rapid growth and adaptability various environments. We report ~339 Mbp draft whole genome sequence J. var. Chai Nat using both PacBio Illumina sequencing platforms. identified categorized differentially expressed genes related biosynthesis lipid toxic compound among four stages development. Triacylglycerol (TAG), major component storage oil, is mainly synthesized by phospholipid:diacylglycerol acyltransferase in Jatropha, continuous expression homologs oleosin over development contributes accumulation level kernels preventing breakdown TAG. A physical cluster for diterpenoid biosynthetic enzymes, including casbene synthases highly responsible compound, phorbol ester, cake, was syntenically conserved between castor bean. Transcriptomic analysis female male flowers revealed up-regulation dozen family TFs flower. Additionally, we constructed robust species tree enabling estimation divergence times nine five commercial crops Malpighiales order. Our results will help researchers breeders increase efficiency this important crop improving yield eliminating cake animal feed.
