Article Abstract

Foxtail millet (Setaria italica) is rich in nutrients and extremely beneficial to human health. We identified and comprehensively analyzed 89 MADS-box genes in the foxtail millet genome. According to the classification of MADS-box genes in Arabidopsis thaliana and rice, the SiMADS-box genes were divided into M-type (37) and MIKC-type (52). During evolution, the differentiation of MIKC-type MADS-box genes occurred before that of monocotyledons and dicotyledons. The SiMADS-box gene structure has undergone much differentiation, and the number of introns in the MIKC-type subfamily is much greater than that in the M-type subfamily. Analysis of gene duplication events revealed that MIKC-type MADS-box gene segmental duplication accounted for the vast majority of gene duplication events, and MIKC-type MADS-box genes played a major role in the amplification of SiMADS-box genes. Collinearity analysis showed highest collinearity between foxtail millet and maize MADS-box genes. Analysis of tissue-specific expression showed that SiMADS-box genes are highly expressed throughout the grain-filling process. Expression analysis of SiMADS-box genes under eight different abiotic stresses revealed many stress-tolerant genes, with induced expression of SiMADS33 and SiMADS78 under various stresses warranting further attention. Further, some SiMADS-box proteins may interact under external stress. This study provides insights for MADS-box gene mining and molecular breeding of foxtail millet in the future.

Proteomic insights into lipid degradation and volatile compound changes during foxtail millet storage.

Food Chem

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.

Structural and deleterious burdens and their effects on yield traits in foxtail millet domestication.

iScience

September 2025

Special Orphan Crops Research Center of the Loess Plateau, Ministry of Agriculture and Rural Affairs, College of Agriculture, Shanxi Agricultural University, Taigu 030801, China.

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.
