Brief bio: I joined the Plant Molecular Biology and Nutrient Metabolism research group leading by Professor Wenzhi Lan in Nanjing University during my PhD candidate. In our research, by using research methods, such as plant molecular biotechnology, plant genetic hybridization, plant morphology analyze, microphotography techniques, etc., we found that VHA-a2 and VHA -a3 are two key proton pumps that assist plant to adapt to aluminum toxicity in Arabidopsis thaliana under acidic environment. We concluded that the suppression of VHA-a2 and VHA -a3 activity accompanied by activating the proton pump and organic acid transporter activity at plasma membrane, which promoted the excretion of intracellular organic acid and protons, and it increased the cell detoxification mechanism. In the future, I plan to discover the further molecular mechanism on plant aluminum toxicity and nutrient absorption.
