Summary: This study demonstrates the essential role of the protein PCaP1 in mediating late responses to oligogalacturonides and flagellin. PCaP1 is not involved in early responses but may be important for maintaining its stability on the plasma membrane through endocytic turnover. The findings suggest a mechanism of PCaP1 endocytosis induced by oligogalacturonides.

Summary: The study reveals the crucial role of PCaP1 in plant immune responses triggered by OGs and flagellin, mainly impacting late responses and affecting the responsiveness of plants to a second treatment with OGs. Localization studies on PCaP1 post-OG treatment indicate its presence on the plasma membrane with specific structures, as well as its association with endocytic vesicles.

Summary: In this study, we identified a wall-associated protein kinase gene GmWAK1 in soybean that plays a crucial role in soybean resistance to the destructive pathogen Phytophthora sojae. Overexpression of GmWAK1 significantly improved soybean resistance to P. sojae and increased the expression of related genes involved in stress responses. Furthermore, we discovered an interaction between GmWAK1 and the annexin-like protein GmANNRJ4, which enhanced soybean resistance to P. sojae.

Summary: Signaling peptide RGF7 in Arabidopsis plays a crucial role in plant immunity by inducing preRGF7 expression, which is regulated by transcription factor WRKY33 and upstream kinases. The perception of RGF7 by receptor complexes RGI4/RGI5-BAK1/SERK4 acts as a new DAMP and enhances Arabidopsis immunity.

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: Citrus and wild relatives have diverse immune responses to microbial features, but flagellin and chitin immune receptors are conserved in cultivated Citrus species. In this study, immune responses of 86 Rutaceae genotypes were analyzed, revealing variation in responses to microbial features within and between members. Differences in chitin and flg22 perception in citrus genotypes were found not to be the result of sequence polymorphisms at the receptor level. These findings provide insights into the diversity of microbial feature perception and identify genotypes capable of recognizing polymorphic pathogen features.

Summary: This study identified the B-deficiency-induced TCH4 gene, which regulates cell wall homeostasis to influence plant growth under B-deficient conditions. The overexpression lines of TCH4 were more sensitive to B deficiency, while the knockout lines of TCH4 were more resistant to low B stress. B deficiency disturbed the arrangement of cellulose, enlarged the gap between cellulose microfibrils, and decreased the mechanical strength of the cell wall, leading to the formation of a thickened and deformed triangular region of the cell wall.

Summary: This study identified AtWAKL10 as a negative regulator of leaf senescence in plants, with its expression regulated by various defense and hormone responsive elements, as well as WRKY transcription factors. Loss-of-function mutant of AtWAKL10 displayed early senescence, while overexpression of AtWAKL10 showed opposite trend, indicating its role in regulating leaf senescence.

Summary: Plants produce reactive oxygen species (ROS) to activate immune responses after pathogen infection. This study identified XCP1 and CYS6 as regulators of pattern-triggered immunity (PTI) and revealed their role in mediating ROS production through the degradation of RBOHD in vacuoles. These findings suggest a conserved strategy for regulating ROS production in plants.

Summary: RH shows significant anti-catabolic effects by inhibiting osteoclastogenesis and bone resorption, potentially through suppressing Nox1 expression, enhancing antioxidant enzyme activity, and inhibiting MAPKs, NF-kappa B, and intracellular Ca2+ oscillation pathways. These findings suggest RH could be a promising natural small molecule for treating osteoporosis by inhibiting excessive osteoclast activity.

Summary: The study revealed that external mechanical cues mimic the role of auxin response factors and katanin in hook formation in dicotyledonous plants. Non-canonical TMK pathway, PIN efflux carriers, and cellulose microfibrils play key roles in hook formation, regardless of the presence or absence of external mechanical cues.
