On planet, there are several species of life, each with a unique set of traits. However, every living creature on Earth is made up of the same fundamental, structural and operational unit of life when seen at the microscopic level. Depending on the form of life, different cells have different chemical compositions, properties and cell types. The cell wall is one of those essential aspects. A cell wall is the non-living material that protects a cell's outermost layer (Anderson et al., 2020). Its composition alters in accordance with the body, it is accessed by nature. The cell wall separates the interior components from the outside world. It influences, supports and protects the development of a cell in addition to its organelles. However, this cellular component is only present in multicellular plants, fungi and a few unicellular organisms. As was already established, fungi too have cell walls, but they are made of chitin, a glucose derivative also found in the exoskeletons of insects. Additionally, they offer structural strength and prevent desiccation, just like plant cell walls do. The plant cell wall is a found naturally nano scale network structure made up mostly of glycoproteins and lignin, as well as polysaccharide polymers like cellulose, hemicellulose and pectin. Plant cells are enclosed in this complex structure, which gives them a variety of sizes, shapes and physicochemical characteristics that enable them to perform their roles in various organs and at different developmental stages. (Almond et al., 2003) The plant cell wall performs a variety of essential functions, such as regulating morphogenesis and architecture, supporting the body of the plant mechanically, transporting nutrients and water, fighting against abiotic and biotic stresses and more. The most abundant and renewable resource on Earth is the plant cell wall, which also has significant practical use for people as a source of natural fibers for the manufacture of textiles and paper as well as for livestock nutrition and heat production. This material's relevance has grown as a result of its potential to be converted into biofuels that can replace fossil fuels. The cell wall of plants is one of the least studied cellular structures in plants, while being crucial for growing plants and having practical applications. Plant cell wall construction varies greatly between species of plants as well as between different tissue types, which is consistent with its involvement in numerous processes. (Abebe et al., 2010) The primary wall and secondary wall are two different wall types that surround plant cells. Young cells develop a dynamic primary wall during division that functions as a flexible and basic supporting structure, shielding the cell and mediating cell-cell connections. Between both the primary wall and plasma membrane is the thicker, more resilient secondary wall, which forms later after the body has stopped growing and dividing. The second wall is regarded as a critical adaptation that enables upright growth and resistance in terrestrial plants.

Cellulose, non-cellulosic and pectin carbohydrates, proteins, phenolic chemicals, and water are typical elements of the cell wall. The main constituents are polysaccharides, whose structure and production have recently undergone thorough scrutiny. The fibrous structure of cellulose, a water-insoluble carbohydrate present among both primary and secondary cell membranes, allows for the preservation of structural integrity. (Barros et al., 2016) Pectin’s are mostly found in the primary cell wall and are undoubtedly the most complex and diverse of the cellulose and hemicelluloses. They have a role in adhesion, expansion, strength, porosity and intercellular signaling. Pectin and non cellulosic polymers can be further separated from cellulose by side chains that are linked to the carbohydrate backbone during production and sugar substitutions. The effects of these substituents on the cell wall's permeability, stiffness and compatibility with other biopolymers. One of the most significant factors determining the cell wall construction or function of the cell wall and its composition. Cell wall composition changed when plants adapt to terrestrial settings, leading to distinct chemical components in various plant species and causing intrinsic variability in terms of chemical and structure. Understanding the structure and function of plant cell walls requires identifying the proteins necessary for the manufacture of the primary cell wall constituents, such as cellulose, hemicellulose, pectin and lignin. Other components of cell wall production include the Golgi transporters and the enzymes needed for nucleotide sugar inter-conversions. (Israel, 1977) The cellular membranes are vital for the existence of bacteria because it protects the viability of the contents of the cell. Antibiotics typically work by lysing bacteria by attacking their cell walls. The outflow of its contents causes the cell to eventually perish. When exposed to various pressures, genes encoding enzymes that can synthesis or hydrolyze parts of the cells of plants exhibit variable expression, which suggests they may promote stress tolerance by altering the composition of the cell wall. In this review, we provide a summary of recent genomic and transcriptomic evidence from the literature that suggests certain cell wall-related genes have a role in stress reactions both in dicot and monocot systems. These investigations show that cell wall modification molecular fingerprints are frequently dynamic and complicated, with numerous genes appearing to react to a single stimulus.
