Lignification is a vital function in plants for improving tolerance against stressors. This article presents studies conducted on the relationship of wheat straw lignin with enhanced plant adaptation against lodging and stressors. Herein, we provide a thorough discussion of the chemical structure and lignin composition of straw and its alteration and uses. Lignin plays a critical role in withstanding harsh environments (biotic and abiotic). Resistance to accommodation in wheat also plays a critical role. Lignin can also produce several products, e.g., costly petroleum-based materials and other vital products, such as resins and composites, and new materials, such as biofuels and chemicals. In this study, wheat straw lignification analysis highlighted that lignin formation regulates cellulose and hemicellulose biosynthesis. In addition, the analysis showed considerable encouragement of lignin growth inside wheat straw and the formation of lignin interfaces, as for cellulose and hemicellulose. Wheat straw lignin is an important source of many essential bioactive moieties, particularly lignocelluloses, straw-based biofuels, and various chemicals. We also explored the molecular tools that influence lignin formation in wheat and the significant strides taken in broadening our understanding of nanotechnology tools. This knowledge could assist in the development of advanced wheat cultivars, increase lignin content, and strengthen feedstock efficiency, reducing the impact of other lignin-associated agronomic gains.
