Summary: PML3 in Arabidopsis is involved in manganese transport, Golgi glycosylation, and cell wall biosynthesis under manganese-deficient conditions. Double mutations of PML3 and NRAMP2 showed improved plant growth under manganese deficiency, indicating opposite roles of PML3 and NRAMP2 in regulating Golgi manganese levels.

Summary: Building a complex structure like the cell wall is a well-orchestrated process that requires assembling many individual parts from different sources within the cell. Cell wall components are actively transported to and from the plasma membrane during diffuse growth. Motor proteins and interactions with the cytoskeleton help transport polysaccharides and enzymes to the correct location for cell wall construction, while newly formed cell walls during cytokinesis have special features.

Summary: In angiosperms, the stability of pollen tube cell walls is regulated by AtGT11, a MUR3 homolog involved in xyloglucan galactosyltransferase activity. Xylosylation of xyloglucan side chains plays a dominant role in cell wall mechanics, while galactosylation finely modifies the mechanical properties of the cell wall.

Summary: The plant cell wall is a complex extracellular matrix that plays a crucial role in defense, regulation, and support. Lipid modifications of proteins involved in cell wall metabolism are essential for proper function, including membrane domain localization and targeted delivery. Understanding the contribution of lipid modifications to protein function is important for elucidating cell wall dynamics.

Summary: Boundary domains play critical roles in plant development by regulating organ growth and morphogenesis through cell growth repression and modulation of cell wall properties. This study reveals the involvement of SPY and CUC2 in leaf boundary domain development, as they repress a common set of genes involved in cell wall loosening. Atomic force microscopy confirms that boundary domain cells have stiffer cell walls compared to marginal outgrowth.

Summary: Endoreplication is a conserved mechanism that regulates cell and organ size by increasing nuclear DNA content. In this study, the researchers found that endoreplication asymmetry, under the control of an auxin gradient, is required for prolonged tissue folding in Arabidopsis. They also identified a molecular pathway linking endoreplication levels to cell size through cell wall remodeling and stiffness modulation. The findings provide insights into the complex relationship between endoreplication and size control.

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: This study identified the FvNST1b gene as a positive regulator of secondary cell wall formation in woodland strawberry. Overexpression of FvNST1b in Arabidopsis resulted in extreme dwarfism and ectopic thickening of secondary walls.

Summary: This study identified a novel Golgi-localized protein named ZINC NUTRIENT ESSENTIAL1 (AtZNE1) in Arabidopsis, which plays a vital role in plant adaptation to excess zinc or iron deficiency. Disruption of AtZNE1 led to growth defects under excess zinc or iron deficiency conditions, highlighting its importance in the regulation of zinc and iron homeostasis.

Summary: Efficient formation of the plant Casparian Strip network relies on communication between neighboring cells, with the protease LOTR1 playing a crucial role. Impaired structure restriction leads to the formation of "half strips" at ectopic positions.

Summary: Self-incompatibility (SI) mechanisms in plants involve the recognition of self-pollen by specific interactions between pollen ligands and stigma receptors, culminating in the rejection of self-pollen. This study reveals that in heading Chinese cabbage, high levels of reactive oxygen species (ROS) produced in stigma papilla cells mediate the SI response, leading to the rejection of self-pollen.

Summary: Flowering plants have developed self-incompatibility and interspecific barriers to prevent the production of unfavorable offspring. Self-incompatibility is achieved by the interaction between S-Locus proteins and S-Locus receptor kinases to reject self-pollen, while interspecific barriers follow the rule of unilateral incompatibility on self-incompatible pistils and unilateral compatibility on self-compatible pistils. In Brassicaceae, S-Locus proteins and S-Locus receptor kinases activate FER-mediated reactive oxygen species production to reject incompatible pollen, while diverged pollen coat proteins trigger nitric oxide to facilitate pollen growth in a preferential manner, maintaining species integrity.
