| description | The plant <i>Tanacetum coccineum</i> (painted daisy) is closely related to <i>Tanacetum cinerariifolium</i> (pyrethrum daisy). However, <i>T. cinerariifolium</i> produces large amounts of pyrethrins, a class of natural insecticides, whereas <i>T. coccineum</i> produces much smaller amounts of these compounds. Thus, comparative genomic analysis is expected to contribute a great deal to investigating the differences in biological defense systems, including pyrethrin biosynthesis. Here, we elucidated the 9.4 Gb draft genome of <i>T. coccineum</i>, consisting of 2,836,647 scaffolds and 103,680 genes. Comparative analyses of the draft genome of <i>T. coccineum</i> and that of <i>T. cinerariifolium</i>, generated in our previous study, revealed distinct features of <i>T. coccineum</i> genes. While the <i>T. coccineum</i> genome contains more numerous ribosome-inactivating protein (RIP)-encoding genes, the number of higher-toxicity type-II RIP-encoding genes is larger in <i>T. cinerariifolium</i>. Furthermore, the number of histidine kinases encoded by the <i>T. coccineum</i> genome is smaller than that of <i>T. cinerariifolium</i>, suggesting a biological correlation with pyrethrin biosynthesis. Moreover, the flanking regions of pyrethrin biosynthesis-related genes are also distinct between these two plants. These results provide clues to the elucidation of species-specific biodefense systems, including the regulatory mechanisms underlying pyrethrin production. |
