- <p>Seed development and maturation are tightly regulated processes governed by <br>complex gene expression networks controlling cellular differentiation, nutrient deposition, <br>desiccation tolerance, and dormancy. This chapter synthesizes current knowledge on <br>transcriptional dynamics from embryogenesis to the fully matured seed, highlighting the <br>roles of key transcription factors such as Leafy Cotyledon (LEC), Abscisic Acid <br>Insensitive (ABI), and Fusca (FUS). The modulatory effects of plant hormones—<br> including abscisic acid, gibberellins, and auxins—are discussed in the context of seed <br>filling and maturation. Advances in transcriptomic tools, particularly RNA sequencing <br>(RNA-seq), have facilitated high-resolution, stage- and tissue-specific profiling, revealing <br>novel genes and networks involved in storage protein synthesis, lipid biosynthesis, and <br>protective mechanisms. Epigenetic regulation, through DNA methylation and histone <br>modifications, adds further refinement to developmental control. Environmental factors <br>and maternal influences are examined for their impact on gene activity and seed <br>phenotype. Understanding these regulatory frameworks offers practical avenues for crop <br>improvement, targeting enhanced nutritional quality, stress resilience, and storage <br>longevity. Future integration of genomics with proteomics and metabolomics holds <br>promise for unraveling the molecular complexities of seed biology and advancing <br>sustainable agriculture. </p>
