Keywords: aquatic plants, cyanobacteria, environmental stress, cyanobacterial blooms, water environment, artificial environment, microplastics, biological calcification, plant electrical signals
My research focuses on the responses of plants and cyanobacteria to abiotic stress and the control of cyanobacterial growth, divided into four areas. 1. The growth and physiological responses of aquatic plants to abiotic stress. I am studying how plants respond to stressors such as microplastics, salinity, and light. 2. Abiotic stress in cyanobacteria. I am researching how cyanobacteria respond to stressors like temperature, light, and microplastics. The goal of studies 1 and 2 is to understand the physiological characteristics of aquatic plants and cyanobacteria under stress. 3. Controlling cyanobacterial growth using the effects of aquatic plants. This study investigates the impact of environmental stressors (salinity, microplastics, light) on the significant relationship between plants and cyanobacteria. 4. Research is being conducted on methods to produce biological building materials without cement by utilizing the biomineralization of cyanobacteria. Additionally, I am studying the effects of electrical signals and electromagnetic radiation on plants.
