Summary: The study explores the functions of Arabidopsis PG45 in organ morphogenesis, revealing its significant role in leaf and flower structure, branch formation, and organ growth. Knockout and overexpression of PG45 result in altered leaf morphology and impaired cell proliferation, accompanied by changes in pectin metabolism and OG profiles. These findings underscore a previously unrecognized function for PGs in tissue polarity determination and cell proliferation regulation, suggesting the presence of OG-based signaling pathways in modulating plant development.

Summary: The lodging of wheat is influenced by the anatomical and chemical characteristics of the stem cell wall. This study examined the plant characteristics related to stem strength in a lodging tolerant mutant (PMW-2016-1) and its parent line (DPW-621-50). The results showed significant changes in the anatomical features and chemical composition of the mutant, including higher lignin content and superior stem strength compared to the parent line. Factors such as the outer stem radius, stem wall thickness, proportion of sclerenchyma tissues, number of large vascular bundles, and lignin content were identified as important for the mechanical strength of wheat stems. The mutant PMW-2016-1 showed promising potential for developing lodging-tolerant wheat varieties.

Summary: Pectin, cellulose, and hemicellulose are important components of the primary cell wall in eudicots and play a vital role in plant development. This study found that PGX2 is involved in regulating root hair development, and its activation tagging affects cell wall remodeling, auxin signaling, and actin microfilament orientation.

Summary: This study demonstrates the feasibility of manipulating the seed coat epidermal cell extracellular matrix using a targeted genetic engineering approach. By expressing enzymes predicted to modify polysaccharide components of mucilage in Arabidopsis thaliana seed coat epidermal cells, researchers observed significant impacts on mucilage composition and cell adhesion, highlighting the complex relationship between cell wall structure and function.

Summary: Low light increases lodging risk by affecting stem elongation and culm thickness. Exogenous uniconazole (UCZ) can improve lodging resistance by increasing culm wall thickness and regulating carbohydrate and lignin-related enzyme contents. It enhances rice lodging resistance under shading conditions.

Summary: This study investigates the role of the polygalacturonase gene MsPG4 in regulating cell wall extensibility and alfalfa resistance to aluminum (Al) stress. The results show that MsPG4 effectively increases cell wall extensibility and Al resistance in alfalfa through hydrolysis of pectins in the cell wall.

Summary: This study investigated the effects of shading stress and planting density on the lignin monomer composition of wheat stems and their relationship with lodging resistance. The results showed that shading led to changes in stem morphology and lignin accumulation, resulting in a decrease in the breaking strength of wheat stems.

Summary: The molecular mechanism of root development mediated by the beneficial bacterium Azospirillum brasilense is not fully understood. A. brasilense induces extensive transcriptional changes but inhibits primary root elongation in Arabidopsis. Through analysis of root cell type-specific markers, it was found that A. brasilense does not alter the overall organization or cell division of the primary root meristem. The inhibition of root elongation is primarily due to the reduction of cell elongation, which is caused by bacterially activated peroxidase leading to cell wall cross-linking. The activation of peroxidase, in combination with the downregulation of cell wall loosening enzymes, results in an increase in cell wall thickness.

Summary: The study showed that pre-treatment with salicylic acid significantly reduced cadmium accumulation in tomato plants and altered cadmium distribution. Salicylic acid induced the composition of the cell wall, increasing cellulose, hemicellulose, pectin, and lignin content, and up-regulated the expression of lignin and cellulose synthase genes while down-regulating pectin methylesterase related genes. Additionally, salicylic acid decreased pectin methylesterase activity to reduce cadmium accumulation in the cell wall and change cadmium partition ratio.

Summary: Pectin plays a crucial role in cell adhesion and environmental adaptations in rice. Overexpression of OsPG2 leads to decreased pectin content and cell adhesion, causing abnormally large intercellular gaps. OsPG2-FOX plants are more sensitive to biotic stresses, but show higher expression levels of disease resistance genes in non-infected leaves and reduced disease symptoms compared to wild-type plants.

Summary: Cell walls are dynamic, multi-component materials that are crucial in plant biology, with their properties modulated by wall-related enzymes. A new method allows simultaneous examination of specific cell wall matrix components, providing insight into direct and indirect consequences of cell wall manipulations. By utilizing this method, researchers can gain a deeper understanding of wall composition, its dynamism, and plasticity, further advancing knowledge of cell wall biology.
