AI Article Synopsis
- Foxtail millet is vital for food and fodder in dry and infertile areas, and research involving 184 recombinant inbred lines (RILs) was conducted for its improvement.
- A total of 483,414 single nucleotide polymorphisms (SNPs) were identified, leading to the creation of high-density bin maps, which updated reference genomes and addressed assembly errors.
- Quantitative trait loci (QTL) mapping revealed important genetic traits, with several controlled by single genes, including those related to plant height and heading date, enhancing tools for foxtail millet research and breeding efforts.
Article Abstract
Foxtail millet (Setaria italica) provides food and fodder in semi-arid regions and infertile land. Resequencing of 184 foxtail millet recombinant inbred lines (RILs) was carried out to aid essential research on foxtail millet improvement. A total 483 414 single nucleotide polymorphisms were determined. Bin maps were constructed based on the RILs' recombination data. Based on the high-density bin map, we updated Zhanggu reference with 416 Mb after adding 16 Mb unanchored scaffolds and Yugu reference with some assembly error correction and 3158 gaps filled. Quantitative trait loci (QTL) mapping of nine agronomic traits was done based on this RIL population, five of which were controlled by a single gene. Meanwhile, two QTLs were found for plant height, and a candidate gene showed 89% identity to the known rice gibberellin-synthesis gene sd1. Three QTLs were found for the trait of heading date. The whole genome resequencing and QTL mapping provided important tools for foxtail millet research and breeding. Resequencing of the RILs could also provide an effective way for high-quality genome assembly and gene identification.

Repetitive DNA contributes significantly to plant genome size, adaptation, and evolution. However, little is understood about the transcription of repeats. This is addressed here in the plant green foxtail millet (Setaria viridis).

Translating biological knowledge from Arabidopsis to crop species is important to advance agriculture and secure food production in the face of dwindling fertilizer resources and biotic and abiotic stresses. However, it is often not trivial to identify functional homologs (orthologs) of Arabidopsis genes in crops. Combining sequence and expression data can improve the correct prediction of orthologs.

Many C4 plants are used as food and fodder crops and often display improved resource use efficiency compared to C3 plants. However, the response of C4 plants to future extreme conditions such as heatwaves is less understood. Here, Setaria viridis, an emerging C4 model grass, was grown under long-term high temperature stress for two weeks (42°C, compared to 28°C).

While the digestibility of millet starch has been studied considerably, the effects of cooking on starch digestibility in millet remain insufficiently understood. This study investigated the effects of cooking on in vitro enzymatic starch digestion in eight cooked millet flour cultivars by seeking its correlations with the changes in composition (moisture, total starch, protein, lipids, total dietary fiber, and phenolics), structure, and physicochemical properties. Compared to raw flours, cooked flours had a similar content of total starch and protein, a lower content of moisture, lipids, and total phenolic content, and a higher content of total dietary fiber.

Foxtail millet (Setaria italica L.) is nutritionally superior to other cereals of the family Poaceae, with the potential to perform better in marginal environments. In the present context of climate change, ecologically sound and low-input foxtail millet varieties can be chosen for agricultural sustainability.
