Summary: Aphid attack often leads to decreased yields and deteriorated fruit quality in cucumber. The overexpression of CsPP2-A1 in cucumber plants resulted in resistance against aphids, with significantly lower colonization rates and reproductions compared to wild type and CsPP2-A1-RNAi plants. CsPP2-A1 played a crucial role in balancing reactive oxygen species (ROS) in plants, and its overexpression increased antioxidant enzyme levels, eliminating ROS and preventing their damage in cucumber. Furthermore, the overexpressed CsPP2-A1 cucumber plants showed nutritional imbalance for aphids and increased content of secondary metabolites, thereby preventing aphid attack.

Summary: This study investigates the role of strigolactones (SLs) in alleviating cadmium (Cd) toxicity in Artemisia annua plants. The results show that SLs improve the photosynthetic performance and Cd tolerance by modulating the antioxidant enzyme system, protecting chloroplasts and pigments, and enhancing glandular trichome (GT) attributes.

Summary: Researchers developed an oxazine-based activatable molecular assembly (PTO-Biotin Nps) that can trigger lysosomal dysfunction-mediated Fenton pathway to induce tumor ferroptosis with excellent spatiotemporal resolution using near-infrared light. The assembly selectively accumulates in lysosomes of tumor cells and exhibits enhanced photothermal activity in the acidic tumor microenvironment. Upon activation, PTO-Biotin Nps induce lysosomal dysfunction, cytosolic acidification, impaired autophagy, and enhanced cellular Fenton reactions to induce ferroptosis, leading to improved antitumor efficacy and reduced systemic side effects.

Summary: When plants are stressed, they release molecules to activate their defense system. Detecting these molecules can help address stress conditions and prevent the development of diseases. In this study, a non-destructive surface-enhanced Raman scattering (SERS)-based nanoprobe is developed for real-time detection of stress-related molecules in living plants. The nanoprobe, placed in the intercellular space, consists of a Si nanosphere surrounded by a corrugated Ag shell modified by a water-soluble cationic polymer. The nanosensors successfully monitor stress-related molecules in different plants, indicating the possible onset of a plant disease. Plasmonic nanosensor platforms could enable early diagnosis of stress and contribute to timely disease management in plants.

Summary: This study investigated the role of LPR1 in Cd stress and found that the overexpression of LPR1 resulted in reduced primary root lengths, fresh weights, lengths of the non-root hair zone, and chlorophyll contents. It also triggered ROS bursts and reduced the entry of available iron into the cell, which induced the expression of IRT1 and exacerbated the Cd influx into plants. These findings highlight the pathway of LPR1-mediated plant response to Cd toxicity stress through the regulation of ROS and Fe homeostasis.

Summary: Elemental bromine is an essential element for human health. Eosinophil peroxidase can catalyze the generation of hypobromous acid, which possesses oxidative and antibacterial properties. However, overexpression or misexpression of hypobromous acid can cause tissue damage and is related to the development of diseases. Therefore, the development of fluorescent probes to detect changes in bromide, hypobromous acid, and eosinophil peroxidase levels has become important.

Summary: Anthropogenic activities contaminate the environment with heavy metals, posing a greater threat than natural phenomena. Cadmium, a highly toxic heavy metal, affects food safety and plant growth. Plants absorb and accumulate cadmium, causing detrimental effects on their morphology and physiology. Plants activate defense mechanisms to tolerate cadmium toxicity by producing antioxidants, up-regulating tolerant genes, and secreting phytohormones.

Summary: This study proposes a SO2-dependent strategy to construct a new functional fluorescence conversion probe MLD-SO2 for two-color visualization of mitochondria and lipid droplets (LDs). The probe selectively targets mitochondria and emits red fluorescence under normal physiological conditions. In the presence of SO2, the probe is converted to a lipophilic structure, targets LDs, and displays strong blue emission. The probe has been successfully used to monitor SO2 changes in zebrafish and mung bean sprouts, making it a powerful tool for studying the interactions between mitochondria and LDs and monitoring SO2 in different organisms.

Summary: We developed a novel ratiometric NIR fluorescent probe for highly sensitive and selective detection of SO2 derivatives in plant mitochondria. The probe can not only target into the mitochondria but also immobilize in the mitochondria to continue detecting SO2 derivatives even when the mitochondrial membrane potential is collapsed by high concentration of SO2 derivatives. It has been successfully used to monitor high concentration of SO2 derivatives in the plant mitochondria when the plant is suffering from SO2 phytotoxicity, indicating that the interaction of SO2 derivatives with plant mitochondria could be an important mechanism for SO2 phytotoxicity.

Summary: This review discusses the deleterious effects of cadmium in plants and the evolution of tolerance and resistance mechanisms. Cadmium negatively affects seed germination, early seedling growth, and plant biomass, as well as photosynthesis, water content, transpiration rate, and electrolyte leakage. Plants have developed detoxification mechanisms to exclude or accumulate cadmium, and utilize signaling pathways, hormone synthesis, antioxidant systems, and other strategies to adapt to cadmium toxicity. Soil microorganisms play a crucial role in reducing metal phytoavailability and enhancing plant morphological and physiological parameters for cadmium tolerance.

Summary: As a new non-invasive treatment method, photodynamic therapy (PDT) has attracted attention in biomedical applications due to the advantages of possessing fluorescence for photosensitizers. The unique features of aggregation-induced emission (AIE) fluorogens provide new opportunities for facile design of light-up probes with high signal-to-noise ratios and improved theranostic accuracy and efficacy for image-guided PDT. The review summarizes recent advances of AIE light-up probes for PDT, introducing strategies and principles for designing AIE photosensitizers and light-up probes and elaborating on their applications in photodynamic antitumor and antibacterial applications.
