Summary: ROS play a vital role in physiological and pathological processes, and research on regulating ROS for disease treatments has gained wide attention. Advances in nanotechnology have led to the development of numerous nanomaterials with the ability to regulate ROS, aiming to find new and effective ROS-related nanotherapeutic modalities. Despite significant progress in ROS-based nanomedicines, there is a need to address fundamental principles for designing ROS-associated nanomedicines to minimize gaps in biomedical applications. This review summarizes current progress in ROS-associated nanomedicines in disease treatments and presents key principles for their design. Future perspectives in the development of ROS-associated nanomedicines are also discussed.

Summary: Land plants have developed defense mechanisms to respond to biotic and abiotic stress conditions by priming their defense responses. Priming, particularly with plant growth regulators such as phytohormones, enhances the plant's ability to respond faster and more effectively to mild stimuli. Cytokinin, a plant hormone involved in regulating photosynthesis and delaying senescence, has been less explored in terms of priming defense or stress-related responses. A comprehensive understanding of the mechanisms of cytokinin-primed defense, especially in relation to photosynthesis, would provide valuable insights into this important group of plant growth regulators.

Summary: The accumulation of phytonutrients in plant tissues can be enhanced by stimulating biosynthesis and providing suitable structures. Artificial chromoplasts induced by the bacterial protein crtB can accumulate high levels of carotenoids and other health-related isoprenoids. Increasing plastoglobule proliferation and reactive oxygen species production can further promote the accumulation of these metabolites and the conversion from chloroplasts to chromoplasts.

Summary: This study investigated the photosynthetic adaptive strategies of hibiscus in response to saline conditions. The results showed that salt stress significantly reduced chlorophyll content and carbon assimilation capacity in hibiscus leaves. The tolerant cultivar DB exhibited higher antioxidant activity and lower ROS accumulation compared to the sensitive cultivar BS, indicating that oxidative damage plays a crucial role in the higher photoinhibition of BS under NaCl stress.

Summary: Hyaluronan (HA) is a natural compound that is found on the cell surface and tissue extracellular matrix. It is synthesized by enzymes and degraded by other substances. HA has different effects on the body depending on its molecular weight, with high molecular weight HA being anti-inflammatory and low molecular weight HA being pro-inflammatory. Reactive oxygen species (ROS) can degrade HA and affect vascular integrity, while HA can also play a role in wound healing. Understanding the interactions between ROS and HA is an important research topic.

Summary: This study investigated the allelopathic potential of different gall morphotypes of Eremanthus erythropappus on Lactuca sativa seeds. It was found that the pentacyclic triterpenes in the extracts of non-galled stems and stem galls had a strong allelopathic effect on seed germination. The galling activity also led to the synthesis and accumulation of new compounds while inhibiting the synthesis of previous compounds.

Summary: The super-host Mimosa gemmulata forms four different galls induced by congeneric Lopesia spp. These galls have distinct morphologies and their development is influenced by the inducer's manipulation of the host plant tissues. Anatomical traits related to trichome differentiation and vascular system arrangement are conserved in M. gemmulata, but altered under the influence of Lopesia spp. The formation of nutritive tissue varies among the different galls and is related to the induction site and original cell lineages. The peculiar traits of the globoid gall are due to its longer lifespan and stronger stimuli-induced responses in all host plant cell lineages.

Summary: This study developed a plant model to investigate the interaction between Cryptococcus gattii and plants. The results showed that C. gattii can grow in plants without causing pathological effects. N. benthamiana exhibited higher proliferation of C. gattii, accompanied by an increase in hydrogen peroxide content, antioxidant system activity, and indoleacetic acid production. Colonies of C. gattii recovered from N. benthamiana displayed altered composition and morphology, as well as increased resistance to antifungal drugs. These findings suggest that plants may serve as a potential reservoir and transmission route for C. gattii.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.
