AI Technical Summary
Technical Problem
There is a demand for industrially producing Stomagen, a peptide that positively regulates stomatal density in plants, while addressing its high degradability and improving storage stability.
Method used
A plant growth composition containing a fusion peptide or its salt, comprising a tag peptide and preservatives like potassium pyrosulfite, potassium sorbate, or potassium gluconate, with a specific weight percentage, to enhance stomatal density and provide storage stability.
Benefits of technology
The composition enables extracellular secretion of the fusion peptide by microorganisms, promoting stomatal density and increasing carbon dioxide uptake, leading to enhanced photosynthesis, crop yield, and sugar content, along with improved tolerance to environmental stresses.

Abstract
The present invention aims to provide a plant growth composition that contains a fusion peptide that has a stomatal density-increasing effect and can be secreted extracellularly when produced by microorganisms, and that has excellent storage stability. [Solution] A fusion peptide or a salt thereof, or a solvate thereof, containing a tag peptide and one of the peptides (A1) to (A3), from the amino terminus to the carboxyl terminus, A plant growth composition comprising a preservative, wherein the preservative is one or more selected from the group consisting of potassium pyrosulfite, potassium sorbate, potassium gluconate, and sodium benzoate, and the total weight percentage of the preservative in the plant growth composition is 0.5 to 5% by weight based on the weight of the plant growth composition.
