Guard cells are specialized cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore. The stomatal pores are largest when water is freely available and the guard cells turgid, and closed when water availability is critically low and the guard cells become flaccid. Photosynthesis depends on the diffusion of carbon dioxide (CO₂) from the air through the stomata into the mesophyll tissues. Oxygen (O₂), produced as a byproduct of photosynthesis, exits the plant via the stomata. When the stomata are open, water is lost by evaporation and must be replaced via the transpiration stream, with water taken up by the roots. Plants must balance the amount of CO₂ absorbed from the air with the water loss through the stomatal pores, and this is achieved by both active and passive control of guard cell turgor and stomatal pore size.

PCT designated stageWO2026087896A1Plant peptidesVector-based foreign material introductionBiotechnologyPlant tissue
Provided is a method for generating a plant having improved growth and / or yield. The method comprises selectively increasing the size of one or more guard cells in a plant wherein the guard cell size is increased compared to guard cell size in an independent wild type control plant of the same species under the same environmental conditions. The ratio of guard cell size to leaf epidermal cell size in the plant is increased as compared to the ratio in the control plant. Also provided is a plant obtainable by the method; a gene construct; a transformed plant part or plant progeny; and a plant part, plant tissue, plant organ, plant cell, plant protoplast, embryo, callus culture, pollen grain or seed, derived or obtained from the plant.

A fusion protein based on optogenetics to regulate endogenous ABA signaling and its applications
This invention belongs to the field of plant regulation and protein engineering technology, specifically relating to a fusion protein that regulates endogenous ABA signaling based on optogenetics and its applications. Specifically, this invention, based on optogenetics, fuses the protein kinase OST1 from the ABA signal transduction component with the optogenetic element cpLOV2, which can be activated / inactivated through dark / light treatment. This achieves the goal of using light to transmit and block ABA signals within the cell to regulate stomatal movement, thereby increasing plant biomass and achieving high and sustainable crop yields, thus possessing significant practical application value.

Method for regulating and controlling opening and closing of plant stomata through optogenetics
The invention discloses a method for promoting opening of plant stomata through optogenetics, and belongs to the technical field of plant growth and development research. By activating the light-operated hydrogen ion pump PPR protein, the length and width of the plant stomata can be regulated and controlled, the stomata opening and closing can be controlled, the opening of the plant stomata is promoted, and the stomata conductance of the plant is improved. The light-operated hydrogen ion pump PPR protein is transferred into guard cells, and the length and width of the pores are regulated and controlled under the illumination condition, so that the opening and closing of the pores are controlled. The opening and closing mechanism does not depend on frequent stimulation of external conditions, but accelerates transmembrane transport of hydrogen ions by means of illumination, so that accurate regulation and control of plant stomata can be realized.
