5-Aminolevulinic acid (ALA), known as a new natural plant growth regulator, can reverse abscisic acid (ABA)-induced stomatal closure. The protein phosphatase 2A (PP2A) played an important role in regulation of stomatal movement by ALA and ABA; however, the underlying molecular mechanisms remain...

Guard cells control the opening of stomatal pores in the leaf surface, with the use of a network of protein kinases and phosphatases. Loss of function of the CBL-interacting protein kinase 23 (CIPK23) was previously shown to decrease the stomatal conductance, but the molecular mechanisms underlying ...

The phytohormone abscisic acid (ABA) regulates ion channel activity and stomatal movement in response to drought stress. Cellular ABA levels change depending on cellular and environmental conditions via modulation of its biosynthesis, catabolism and transport. Although factors involved in ABA...

Tomato is often exposed to high temperature stress during summer cultivation. Stomatal movement plays important roles in photosynthesis and transpiration which restricts the quality and yield of tomato under environmental stress. To elucidate the mechanism of stomatal movement in high temperature...

Aim: Hydrogen sulfide (H₂S) is a gaseous signaling molecule that participates in multiple physiological processes in both animals and plants. Mitogen-activated protein kinase (MAPK) is important signaling molecule that links the growth and developmental signals and environment stimuli to cellular...

CO₂ uptake and water loss in plants are regulated by microscopic pores on the surface of leaves, called stomata. This enablement of gas exchange by the opening and closing of stomata is one of the most essential processes in plant photosynthesis and transpiration, affecting water-use efficiency...

Increasing stomatal movement is beneficial to improve plant water use efficiency and drought resilience. Contradictory results indicate that aquaporins might regulate stomatal movement. Here, we tested whether the maize plasma membrane PIP2;5 aquaporin affects stomatal closure under water deficit,...

5-Aminolevulinic acid (ALA) is a new natural plant growth regulator that inhibits abscisic acid (ABA)-induced stomatal closure. Studies have shown that protein phosphatase 2 A (PP2A) is involved in ALA-ABA antagonistically regulating stomatal movement; however, the molecular mechanisms underlying...

Introduction: Cotton is a vital industrial crop that is gradually shifting to planting in arid areas. However, tubby-like proteins (TULPs) involved in plant response to various stresses are rarely reported in cotton. The present study exhibited that GhTULP30 transcription in cotton was induced by...

Sunflecks are transient patches of direct radiation that provide a substantial proportion of the daily irradiance to leaves in the lower canopy. In this position, faster photosynthetic induction would allow for higher sunfleck-use efficiency, as is commonly reported in the literature. Yet, when...
