Summary: This review summarizes the important functions of flavonols in plant growth and development. Mutants with reduced flavonol levels, especially the transparent testa mutants in Arabidopsis thaliana, have contributed to our understanding of flavonol biosynthesis. These mutants have also revealed the roles of flavonols in controlling development in different tissues and cell types, including root architecture, guard cell signaling, and pollen development. Recent progress has highlighted that flavonols function as reactive oxygen species (ROS) scavengers and inhibitors of auxin transport, modulating plant growth, development, and responses to abiotic stresses.

Summary: Xylooligosaccharides (XOS), major byproducts of biofuel production, can trigger stomatal closure in Arabidopsis by inducing the production of ROS and NO, mediated by salicylic acid signaling and independent of ABA signaling.

Summary: This review examines the role of nitric oxide (NO) in controlling plant growth, development, metabolism, and stress responses through its interactions with light and hormonal signaling cascades. It also discusses the versatile functions of NO in regulating photosynthesis and stomatal movements, highlighting the importance of nitrate reductase (NR) regulation for adjusting NO production in plants exposed to natural light conditions.

Summary: The localization of phytochromes in guard cells or mesophyll cells does not have a predominant direct role in the opening or closure of stomata in Arabidopsis. The exact mechanism of phytochromes in blue- and red-light-mediated stomatal opening, and far-red-light-mediated decrease in opening, is still uncertain. The study suggests that phytochromes may indirectly affect stomatal opening through their influence on leaf growth and stomatal development.

Summary: Red light can positively influence plant defense mechanisms against biotic stress by increasing levels of salicylic acid and inducing SA signaling mediating the production of reactive oxygen species. These changes in SA levels are crucial for plant survival.

Summary: Plant defense responses can be triggered by the application of elicitors such as chitosan, leading to rapid stomatal closure and production of reactive oxygen species and nitric oxide. These responses are influenced by phytohormones like ethylene and external factors such as light, with the expression of hormone-mediated defense genes playing a crucial role.

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 evolution of photosynthesis in plants has been crucial but has also led to challenges in the form of reactive oxygen species (ROS) production. Multiple forms of ROS are generated in various plant cell compartments, requiring a sophisticated network of ROS detoxification and signaling tailored to individual organelles to safeguard the cell as a whole.

Summary: Stomatal defences, mediated by apoplastic ROS, are vital for plants to prevent pathogen entry. This study sheds light on the role of NADPH oxidase RBOHF in the interplay between apoplastic and cytosolic ROS dynamics during stomatal immune response. Surprisingly, the rbohF mutant showed unexpected over-oxidation of the H2O2 sensor roGFP2-Orp1, while being impaired in PAMP-triggered stomatal closure and apoplastic alkalinisation.

Summary: Cancer is a major global cause of death, with the role of reactive oxygen species (ROS) in cancer development and progression being extensively studied. However, conflicting evidence exists regarding the specific impact of ROS on cancer, which may vary depending on the type of cancer and stage of tumorigenesis. Recent research has focused on exploring the diverse aspects of ROS interaction with cancer at different stages of cancer progression.

Summary: This study suggests that fine tuning the stability of phytochrome (Pfr) is a fundamental mechanism for plants to optimize phytochrome-related traits in their evolution and adaptation to spatially varying environments. The research revealed evolutionary divergence in physiological responses relevant to thermal stability of Pfr between two sister species of Brassicaceae, with the higher latitude species showing stronger responses to light-limited conditions.

Summary: Climate change has devastating effects on plants, leading to the production of reactive oxygen species (ROS) as byproducts of oxygen consumption. While excessive ROS can disrupt cellular homeostasis, moderate levels can activate growth and stress responses in plants, though the exact mechanisms are not fully understood. Advancements in modern techniques like molecular priming and crop modeling offer potential solutions for managing ROS levels in plants under stress.

Summary: Reactive oxygen species (ROS) and the photoreceptor protein phytochrome B (phyB) play a key role in plant acclimation to stress. This study reveals that phyB and respiratory burst oxidase homolog proteins (RBOHs) act as part of a regulatory module that controls ROS production, stress-response gene expression, and plant acclimation to excess light stress. The findings also demonstrate that phyB can regulate ROS production even if it is restricted to the cytosol and that phyB and RBOHD/RBOHF co-regulate the expression of thousands of genes in response to light stress. Additionally, phyB is found to be necessary for ROS accumulation during heat, wounding, cold, and bacterial infection.
