Summary: In this study, two crucial cis-acting elements, 5'-CACGAGA-3 'and 5'-CACATGTTTCCC-3', were found to be essential for the guard cell-specific expression of SCAP1 and HT1. The findings reveal a novel transcriptional regulatory mechanism that synchronously promotes the expression of multiple genes required for stomatal maturation and function.

Summary: The study investigates the negative regulatory role of mitogen-activated protein kinase 11 (MPK11) in red light-induced stomatal opening in plants. It is found that MPK11 is highly expressed in guard cells and localized in both the nucleus and cytoplasm. White light upregulates the transcript levels of MPK11 in guard cells, and the mpk11 mutant exhibits a larger stomatal aperture under white light. Moreover, red light also upregulates the transcript levels of MPK11 in guard cells, and the mpk11 mutant shows a larger stomatal aperture under red light.

Summary: Blue and red light are important light signals for regulating stomatal development and leaf structure. This study investigated the response of stomatal and leaf traits in soybeans to blue and red light at two light intensities. The results showed that stomatal size remained unchanged under blue light, while stomatal density, specific leaf weight, and maximum stomatal conductance were unaffected by the decrease in light intensity under red light. These findings suggest that stomatal density and specific leaf weight are regulated by blue light, while stomatal size is highly sensitive to red light. Furthermore, specific leaf weight and stomatal density had the highest contribution rates to maximum stomatal conductance. Overall, these results indicate that long-term exposure to blue light enhances maximum stomatal conductance through the synergistic promotion of specific leaf weight and stomatal density.

Summary: The study identified 17 protease inhibitors that can inhibit light-induced stomatal opening, with the top three (PI1, PI2, PI3) acting by suppressing the activity of H+-ATPase. These inhibitors were predicted to target factors involved in the process of light-induced stomatal opening through bioinformatics analysis.

Summary: Stomatal guard cells are specialized cells that respond to stimuli such as blue light and abscisic acid for regulating stomatal aperture. Several GC-specific genes, including ALMT6, were identified to play important roles in stomatal movement, particularly in the opening process. The study highlights the significance of GC-specific genes in stomatal regulation and provides new insights into the molecular mechanisms involved.

Summary: Changes in chloroplast metabolism play a critical role in the comprehensive cellular response to challenging environments, starting with rapid modifications of processes in the thylakoid membrane, followed by changes in the stroma and transport activities across the chloroplast envelope. Understanding the characteristics of the 'modulators' involved is essential for enhancing plant stress tolerance and developing targeted breeding strategies.

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: This study demonstrates that overexpression of Arabidopsis plasma membrane H+-ATPase (AHA2) in guard cells of transgenic hybrid aspens enhances light-induced stomatal opening, photosynthesis, and growth. The results show that manipulating the expression of PM H+-ATPase in guard cells can positively impact the growth of perennial woody plants.

Summary: Plants have two cryptochrome photoreceptors, CRY1 and CRY2, which mediate overlapping and distinct physiological responses. This study identified 19 phosphorylation sites in CRY1 and analyzed the physiological and photobiochemical activities of CRY1 variants with phosphosite substitutions. The results showed that phosphorylation of CRY1 is necessary for its degradation, physiological functions, and interaction with the E3 ubiquitin ligase COP1. Additionally, the phosphorylation of CRY1 by photoregulatory protein kinases (PPKs) is critical for CRY1 signaling and regulation.

Summary: The study systematically investigated the expression patterns of 19 putative Guard-cell-enriched GDSL Lipases (GGLs) in Arabidopsis, revealing diverse expression patterns in guard cells. Most GGLs were localized in the endoplasmic reticulum, and some in lipid droplets and nucleus. Further analysis showed the correlation of expression pattern and biological function, as well as the functional redundancy of GGLs in plant development and environmental adaptations. Phenotypic identification of ggl mutants indicated unique and redundant roles of GGLs in stomatal dynamics, density, morphology, and plant water relation, providing insights for controlling stomatal dynamics and development, plant growth, and adaptation to the environment.

Summary: The study shows that blue light-induced stomatal opening in plants is mediated by the BLUS1 signaling pathway, which regulates the opening and closure of stomata, thereby affecting CO2 uptake and transpiration.

Summary: The ion transport and metabolism of guard cell membrane are closely related and critical for stomatal opening. Organic metabolites in guard cells play various roles during stomatal opening, but their origin and fate are still debated. Recent research highlights the tight correlation between mesophyll and guard cell metabolism.

Summary: In this study, the role of MPK4 in stomatal immune response was explored through overexpression in Arabidopsis. The MPK4-associated protein complex in guard cells was characterized, and four new interacting proteins were identified. These findings shed light on the functions of MPK4 in guard cells and provide new targets for further research.
