Summary: This article explores the effects of ozone on stomatal regulation focusing on the role of phytohormones in guard cell signaling. It updates existing knowledge on physiological mechanisms related to stomatal regulation after ozone response, deepening understanding of molecular pathways associated with ozone stress response. After summarizing the findings and noting gaps in the literature, some future research directions on ozone stress in plants are proposed.

Summary: Glutamine (Gln) is the first synthesized amino acid in plant nitrogen assimilation. Glutamine synthetase (GS), an ancient enzyme, converts glutamate (Glu) and NH4+ into Gln at the expense of ATP. Plants have multiple GS isoenzymes that ensure sufficient Gln supply for growth and development. Gln serves as a building block for protein synthesis and as a nitrogen donor for the biosynthesis of various molecules.

Summary: Beneficial interactions with microbes can modulate root branching plasticity in plants, and the plant microbiota influences root branching in Arabidopsis thaliana. The microbiota can control root branching independently of the phytohormone auxin and requires the induction of ethylene response pathways.

Summary: A highly efficient fluorescent probe was developed for selective and quantitative detection of ethylene in living biological systems. The probe showed great potential for elucidating the spatiotemporal regulation of ethylene biosynthesis and signal transduction in different cells and plants.

Summary: This article focuses on recent advances in elucidating the functions of Iron (Fe) signaling components. The paper discusses the Fe acquisition systems that control Fe uptake from soil, the major components that regulate Fe uptake systems, and the perception of Fe status in Arabidopsis thaliana and Oryza sativa. Further exploration of Fe signal transduction will pave the way for understanding the regulatory mechanisms underlying the maintenance of plant Fe homeostasis.

Summary: Plants, as sessile organisms, have evolved complex stress-responsive signaling pathways to regulate the expression of transcription factors and biosynthesis of osmolytes for tolerance. Signaling peptides, acting like phytohormones, control various aspects of plant growth and development through cell-cell communication networks. Recent studies have shown the importance of several signaling peptides in plant responses to abiotic stress.

Summary: The study identified a hub gene RhWRKY33 through transcriptome analysis, which accumulated in the nucleus and showed higher expression in petals treated with wounding, ethylene, and EW. Functional characterization of RhWRKY33 through gene silencing demonstrated its positive regulation in delaying petal senescence, particularly under ethylene and wounding dual-treatment. The results suggest that RhWRKY33 plays a crucial role in mediating petal senescence under ethylene and wounding signaling pathways.

Summary: Critical issues include the highly compartmentalized changes in mitochondrial ROS production during acute hypoxia and the necessity of using redox-sensitive probes targeted to specific compartments to fully understand the role of mitochondrial ROS in acute O-2 sensing. Future studies are needed to specify the ROS and characterize the target(s) of ROS in chemoreceptor cells during acute hypoxia, to contribute to a more complete understanding of the implication of ROS in acute responses to hypoxia.

Summary: The pollution of agricultural soils by Cadmium (Cd) leads to decreased crop yield and contamination, which poses a threat to human health. The adverse effects of Cd on plant growth occur at various levels, and can be explained by Cd-induced interference in regulatory networks mediated by plant phytohormones. Abscisic acid (ABA) and ethylene both regulate Cd accumulation and tolerance in plants, and their interaction contributes to plant adaptation to stress conditions.

Summary: Iron deficiency-induced chlorosis in plants depends on phosphorus availability and is regulated by a ROS-mediated retrograde signaling pathway involving the PHT4;4 chloroplast ascorbate transporter and the bZIP58 nuclear transcription factor. These genes prevent downregulation of photosynthesis genes under iron-phosphorus deficiency, leading to a stay-green phenotype. Chloroplastic ascorbate transport modulates ROS homeostasis to adapt photosynthesis to nutrient availability.

Summary: Research shows that ethylene and its precursor regulate root hair formation by increasing ROS accumulation. Ethylene-sensitive mutants have increased root hair number and ROS accumulation, while ethylene-insensitive mutants show the opposite effect.

Summary: Reactive oxygen species (ROS) are essential signaling molecules in plant responses to environmental stimuli and development. Antioxidant enzymes play a critical role in scavenging ROS and their regulation is influenced by both environmental conditions and transcriptional activation.

Summary: Pollen-pistil interaction is a fundamental process in flowering plant reproductive biology and is regulated by hormones such as ethylene (ET) and cytokinin (CK). These hormones play a role in multiple stages of development and growth, including pollen adhesion, germination, and growth.
