Abstract

Particularly in regions with poor growing conditions, seed vigour is essential to millet cultivation since it impacts germination rates, seedling emergence, and crop output. New genomics research has allowed us to learn more about genetic factors affecting seed vigour. This study aims to provide a comprehensive genomic analysis of millet to identify critical genetic loci and underlying biochemical mechanisms that regulate seed vigour. Using advanced methods from comparative genome sequencing, gene expression profiling, and genome-comprehensive association studies (GWAS), we identify the genes and structures of regulation crucial for enhancing seed vigour in this research. The findings provide valuable information that breeding programs may utilize to improve millet seed quality and yield.

Conclusion

This work used extensive genomic analysis to reveal the genetic architecture of millet seed vigour features. Breeders may now improve millet seed vigour features thanks to the discovery of novel molecular targets for marker-assisted selection, made possible by identifying significant SNPs on chromosomes 3, 5, and 8. Transcriptome research also showed that hormone modulation, especially gibberellin and abscisic acid signalling, is critical for seed vigour. Consistent with previous studies in cereal crops, our results highlight the importance of these pathways in enhancing seed quality in all species.

Seed vigour is a complicated attribute, and identifying differentially expressed genes in stress response and glucose metabolism only adds to that complexity. These molecular insights provide the groundwork for future breeding programs that might raise millet yields by improving seed quality, crop establishment, and overall yield, particularly in areas with difficult growing circumstances.

The future of understanding the processes influencing seed vigour hinges on integrating multi-omics technologies like metabolomics and proteomics with environmental interaction research. By focusing on these areas for the future, we may improve our breeding efforts and produce millet varieties that can withstand the effects of climate change and other agricultural threats, ensuring that the world's food supply remains stable.

Genomic techniques to boost seed vigour may ensure that millet remains a robust crop, which will help with sustainable agriculture and food security in areas vulnerable to environmental pressures.
