General Introduction: 

Established in 2014, the Research Group of Aquatic Plant Physiology focuses on multiple aspects of aquatic plant research, including morphology, physiology, molecular biology and genomics.  

Major research areas: 

The regulation of plant phenotype by environmental factors: Using water wisteria (Hygrophila difformis) as a model, this group studies the impact and regulatory mechanisms of environmental factors, genes and phytohormones on plant phenotype. 

Duckweed research and applications: This group has collected over 18 species of duckweed, including Spirodela, Landoltia, Lemna, Wolffiella, and Wolffia. Starting from duckweed germplasm preservation, tissue culture, and genetic transformation, they study the response mechanism of duckweeds to low phosphorus signal, selected suitable duckweed species for biomonitoring and phytoremediation, and set up bioreactors to express fish vaccines. 

Aquatic plant ecology: They use molecular tools, such as AFLP, MSAP, and SSR to study the distribution, genetic diversity and ecological function of aquatic plants in some important lakes of the plateau and drainage areas of the Yangtze River.  

Aquatic vegetables and ecological agriculture research and application: They study the physiological and gene profiles of important aquatic vegetables including Oenanthe javanica and Nasturtium officinale under abiotic stress, identify important trait genes, and screen germplasms for quality traits. They also design floating beds of aquatic vegetables to improve water quality.
