Morphological variations and draft genome of lalumai, a Taiwanese indigenous crop.

Spodiopogon formosanus Rendle is one of the important indigenous grains in Taiwan. This plant is used for food and herbal medicine by Taiwanese indigenous people. Because of its tolerance of drought and nutrient-rich seeds, it is supposed as a potential future corp and energy crop. However, while some indigenous stories and terms about this plant have inferred its sources and characters, its origin is still unknown. Moreover, no study had been explored the genetic basis of its nutrition and medicinal chemistry. To provide these fundamental biological information of this plant for its further applications, in the present study, we aimed to assemble a draft genome, screen for genes and biological processes associated with medicinal and nutritional chemical constituents, and improve current understanding of its origins. Our preliminary GO analyses predicted 5,820 GO biological processes and 17,860 genes. The preliminary screen suggests a number of GO biological processes and genes were associated with the lipid metabolism, wax biosynthesis, and oxidation–reduction processes. Comparisons among S. formosanus plastomes and plastomes from other grass species indicate that S. formosanus is a member of the clade (subtribes Anthistiriinae + Andropogoninae). Plastome structure, component, and gene orientation of S. formosanus are similar to most of plastomes from other grass species.
