Summary: SNARE proteins play important roles in plant growth and development, as well as abiotic stress resistance. This study identified and analyzed 52 SiSNARE genes in foxtail millet, showing tissue-specific expression and differential responses to drought stress in different cultivars. The findings provide valuable genomic information for further research on drought stress response in foxtail millet.

Summary: SimR396d, a highly expressed miRNA in the roots of foxtail millet, is involved in root growth and response to abiotic stress. Overexpression of SimiR396d enhances drought tolerance and root length, while knockdown of SimiR396d expression reduces drought tolerance and root length. The transcription factor SiGRF1, which is a direct target of SimiR396d, suppresses root growth and reduces sensitivity to drought stress when overexpressed. Ethylene signaling is necessary for the regulation of plant root growth by SimiR396d and SiGRF1.

Summary: In this study, 72 SiSAUR genes were identified and named according to their chromosomal distribution in the foxtail millet genome. These genes were classified into three groups based on phylogenetic tree analysis, and showed similar gene structure and motif composition characteristics within each group. Analysis of cis-acting elements in the promoter region revealed the presence of hormone and stress response elements. Gene replication analysis indicated that many SiSAUR genes were derived from gene duplication events. Furthermore, the expression of 10 SiSAUR genes was induced by abiotic stress and exogenous hormones, suggesting their involvement in complex physiological processes.

Summary: This study identified and characterized 57 GRAS genes in foxtail millet, dividing them into 13 subfamilies based on conserved domains and gene structure. The genes were unevenly distributed across chromosomes, with significant differences in expression in different tissues and stages of fruit development. Exogenous treatment affected plant height, fruit weight, and gibberellin content, indicating potential for genetic improvement in foxtail millet.

Summary: Salinity and water deficit are major stresses affecting crop quality in dry areas. This study investigated the effects of soil water levels and salinity levels on foxtail millet and found that higher soil salinity levels decreased grain yield but increased water productivity, providing guidelines for foxtail millet cultivation in saline soils.

Summary: In this study, 93 MAPK cascade genes were identified in foxtail millet through genome-wide analysis. The expression of most SiMAPKs and SiMAPKKs were found to be altered under hormone and stress treatments, with SiMAPK3 and SiMAPKK4-2 being consistently induced and SiMAPKK5 being repressed.

Summary: Through phylogenetic tree analysis, foxtail millet bHLH genes were divided into 21 subfamilies and two orphan genes, with subfamilies 15 and 18 possibly experiencing stronger expansion in evolution. Sixteen tandem repeat events and thirty-eight pairs of segment duplications were identified. The study revealed significant differences in transcription levels of SibHLH genes in different tissues, fruit development stages, and various abiotic stress conditions.

Summary: Salt stress is a significant limiting factor for crop production. In this study, we found that SiDi19-3 interacts with SiPLATZ12 to regulate salt tolerance in transgenic Arabidopsis and foxtail millet seedlings. Overexpression of SiDi19-3 increased the transcript levels of various salt-responsive genes and improved salt tolerance in foxtail millet and Arabidopsis. Our findings suggest that SiDi19-3 and other SiDi19 members play important roles in regulating salt tolerance and other abiotic stress responses in foxtail millet.

Summary: Climate change has led to severe drought, impacting global crop production. Broomcorn millet, which is a drought-tolerant crop known for its short life cycle and high water use efficiency, is commonly used in water-saving agriculture. This study evaluated the drought tolerance of 300 broomcorn millet varieties and found that drought stress decreased photosynthetic capacity and triggered transcriptome reprogramming. Additionally, melatonin treatment enhanced drought resistance in the broomcorn millet varieties.

Summary: This study investigated the effects of light drought stress and heavy drought stress on the panicle morphology, photosynthesis, antioxidant protective enzyme system, reactive oxygen species (ROS) system, osmotic regulatory substance and RNA-seq of foxtail millet. The findings reveal that drought leads to decreased panicle length and weight, increased empty abortive rate, and reduced yield. Photosynthesis is also significantly reduced, along with increased levels of peroxidase and H2O2. RNA-seq analysis identified numerous differentially expressed genes in response to drought stress. These findings provide a comprehensive understanding of the impact of drought on foxtail millet yield formation.
