Foxtail millet (Setaria italica) is one of the most ancient cultivated cereal crops and is ideal for the functional genomics of the Panicoideae crops. In the present study, we generated an F population consisting of 300 individuals by crossing an elite foxtail millet variety Jingu28 with a backbone line Ai88, and constructed a genetic linkage map with 213 published SSR markers and two InDel markers. Quantitative trait locus (QTL) mapping identified 46 QTL for 12 agronomic traits, including 13 major effect QTL. Meanwhile, 40 QTL controlling different traits formed 13 co-located QTL clusters. Moreover, one putative candidate gene Seita.9G020100 for qHD9-1 with conserved CCT motif and a gibberellin biosynthesis related GA20 oxidase gene Seita.5G404900 for qPH5-1 were identified based on homologous gene comparison. The 277 bp insertion/deletion on the promoter of Seita.9G020100 and the one-base (G) insertion/deletion in the third exon of Seita.5G404900 might be candidate functional sites. Furthermore, two markers (Ghd7InDel and GA20oxSTARP-1) were developed based on these two variation sites, respectively. These results will help to elucidate the genetic basis of important agronomic traits in foxtail millet and be useful for marker-assisted selection of varieties with ideal plant architecture and high yield potential.

Foxtail millet quality deteriorates during storage, but the mechanisms behind aging-related changes are not fully understood. This study investigated lipid degradation and volatile compound changes in stored foxtail millets, employing proteomics to uncover underlying quality decline mechanisms. After 30 days, fatty acid contents increased, accompanied by a general coarser grain surface texture.

Liqueur koji-fermented foxtail millet beverages offer distinctive flavors and health benefits, but the interrelationships among flavor compounds, sensory properties, and antioxidant activity remain unelucidated. This study systematically mapped dynamic changes across a standardized 72 h fermentation using chromatographic, electronic sensory approaches, and antioxidant assays. Key results revealed glucose, lactic acid, and succinic acid as primary taste-active indicators through HPLC.

Crop domestication typically accumulates structural and deleterious variants through genetic bottlenecks and selection hitchhiking. However, the structural and deleterious variant burden has not been investigated in the foxtail millet (). Integrating comparative genomics, pangenomics, population genetics, and quantitative genetics, we identified 6,713 gene gains and 2,802 losses during domestication, affecting flowering time and developmental processes.

Our understanding of how photosynthetic capacity varies among C species and across growth and measurement conditions remains limited. We collated 1696 CO response curves of net CO assimilation rate (A/C curves) from C species grown and measured at various environmental conditions and used these data to estimate the apparent maximum carboxylation activity of phosphoenolpyruvate carboxylase (V) and CO-saturated net photosynthetic rate (A), two key parameters describing photosynthetic capacity. We examined how V and A vary with species-specific traits, growth and measurement conditions.

Efficient and fast water uptake by seeds, facilitated by optimal soil moisture, plays a critical role in timely germination and early seedling vigor for foxtail millet production in arid and semi-arid regions. The husk, as a unique structure through which the seed contacts the soil, plays an important role in water uptake and germination. Many foxtail millet germplasm accessions have papillae on the epidermis of their husks, yet the role of this trait in water uptake and germination, as well as the genetic basis and regulatory mechanism related to this trait, remain unknown.
