Article Abstract
Background: Dehydration response element binding factors (DREBs) are a family of plant-specific transcription factors that regulate plant responses.
Results: In this study, members of the SiDREB gene family were identified and analyzed in terms of their physicochemical properties, phylogeny, and structure of the encoded proteins. The expression patterns of the DREB transcription factors in foxtail millet under stress were analysed by combining the qRT-PCR data for foxtail millet after exposure to low temperature, abscisic acid (ABA), and osmotic stress (20% PEG 6000). There were 56 SiDREB genes, which were divided into six subgroups, that were located on nine chromosomes of foxtail millet. Chromosomal localization showed that the SiDREB genes were unevenly distributed across nine foxtail millet chromosomes. Furthermore, qRT‒PCR experiments revealed that 19 SiDREB genes play a role in the response to abiotic stress and ABA.
Conclusions: The results of this study lay a foundation for further research on the functions of the DREB genes in foxtail millet and will be beneficial foe the genetic improvement of this species.

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.
