Summary: Cyanobacterial toxins are found to disrupt the plant cytoskeleton and affect the structure and composition of the cell wall. This study investigated the alterations in cell wall matrix after treatments with cyanotoxins in rice root cells. The distribution patterns of homogalacturonan and arabinan were found to be altered, along with changes in pectin methylesterase activity. Increased intracellular Ca2+ levels, callose and mixed linkage glucans deposition were observed. The exact mechanism of cyanobacterial toxicity against the cell wall needs further investigation.

Summary: This research evaluated the effects of boron toxicity on the cell wall architecture of Chinese chestnut pollen tubes. The results showed that boron toxicity inhibited pollen germination and led to abnormal morphology of the pollen tubes. It also altered the distribution and structure of cell wall components, including pectins, cellulose, and callose, and affected their relationship.

Summary: The cell wall of mature pollen grain is a specialized structure with outer sporopollenin-based exine for protection and inner cellulose-based intine for germination. The complex process of wall development involves the deposition of multiple cell wall polymers in a controlled sequence. The development of tomato pollen wall has been described with a timeline of key events, including exine deposition, tapetum degeneration, and intine formation during pollen maturation.

Summary: This study analyzed the transcriptome, proteome, and N-terminome of Zea mays leaves treated with different substances to explore cell processes related to cell death and plant immunity. The results showed distinct and time-dependent biological processes being activated in response to different substances. The correlation analysis of the transcriptome and proteome identified general and trigger-specific markers for cell death in Zea mays. Additionally, specific regulation of proteases, particularly papain-like cysteine proteases, was observed during regulated cell death.

Summary: This study evaluated agronomical and stem description traits in a subset of maize inbred lines and determined the influence of cell wall composition on these traits. The results showed that a high proportion of lignin subunit G and a low concentration of p-coumaric acid and lignin subunit S were beneficial for greater rind puncture resistance, taller plants, and higher biomass yield. Additionally, a higher proportion of subunit H was associated with longer internodes, while a lower total hemicellulose content was related to greater rind puncture resistance.

Summary: The malfunction of p60-katanin in cell plate/daughter wall formation in the fra2 Arabidopsis thaliana loss-of-function mutant was investigated. Deviations in the chemical composition of cell plate/new cell wall were identified by transmission electron microscopy (TEM), immunolabeling, and confocal microscopy. Delayed cytokinesis in the mutant results in a loss of synchronization between cell plate growth and chemical maturation.

Summary: Plant cells can undergo regulated cell death in response to exogenous factors or as a regular element of development. The cellular aspects of these death responses differ, indicating differences in early signaling. This study uses cytokinin-induced programmed cell death as a paradigm to investigate the role of the cytoskeleton in developmentally induced cell death.

Summary: Proteins with specific carbohydrate-binding lectin domains play important roles in regulating and monitoring the cell wall during plant development. A genome-wide screening and transcriptomic analysis of maize roots identified a set of lectins with high expression levels and differential regulation, which are predicted to be involved in cell wall metabolism and have direct access to the cell wall. These lectins have potential roles in the early stages of root morphogenesis.

Summary: Cell wall architecture plays a crucial role in stalk strength and forage digestibility. This study utilized genetic mapping techniques to investigate the development of cell wall during secondary cell wall lignification in maize stalks and identified QTLs associated with cell wall components and digestibility traits. The findings indicate that cell wall-related traits are regulated by multiple genes, with stage-specific expression after silking.

Summary: Differentiation of spore mother cells marks the transition from somatic cells to reproductive cells in higher plants. These cells are critical for fitness as they differentiate into gametes, leading to fertilization and seed formation. In maize, the growth of ovule primordium and the geometry of the ovule drive the specification and elongation of the megaspore mother cell (MMC).

Summary: The plant cell wall serves as an important extracellular matrix that envelops cells, maintains their shape and structure, interacts with symbionts, and protects against external stresses. The assembly of this matrix is regulated by the cytoskeleton, which also plays a key role in perceiving mechanical cues and mediating intracellular responses related to cell wall structure changes. Delivery processes of cell wall precursors and their structural continuity are crucial for cell wall assembly, with various morphogenetic processes relying on cell wall assembly as a critical element.

Summary: The study revealed that in tomato plants, PIN1 disappeared in giant cells after being infected by Meloidogyne incognita, indicating the maintenance of a local auxin maxima. This phenomenon could be attributed to the nematodes' nutritional needs throughout its life cycle or the differential responses of tomato plants to M. incognita infection.

Summary: In this study, the effect of the connection strand formed between neighboring stomata in Amaryllidaceae plants on stomatal morphology and function was investigated. The connection strand was found to be mainly composed of pectins, with the presence of crystalline cellulose and extensins. The connected stomata exhibited different opening characteristics compared to single stomata, indicating that the connection strand could affect stomatal function.

Summary: In this study, new isolates from specific Greek environments were investigated for their ability to degrade crude oil, and a Pseudomonas plecoglossicida isolate demonstrated the highest percentage (76.7%) ability to degrade crude oil. The presence of specific genes and the ability to form agglomerates or release surfactants were also investigated. The study suggests that these bacterial isolates may provide a novel alternative to various bioremediation processes or be used as inocula in autochthonous bioaugmentation procedures for crude oil biodegradation.
