Research Interests :
Searching for regulatory genes that confer drought tolerance to Arabidopsis thaliana
Abiotic stresses, such as drought, salinity, extreme temperatures, chemical toxicity and oxidative stress are serious threats to agriculture and is the primary cause of crop loss worldwide, reducing average yields for most major crop plants by more than 50%. However desiccation/drought stress tolerant plants exist in different places, and genes confer stress tolerance are everywhere. Desiccation of seeds is considered to be a prerequisite for the completion of life cycle; desiccation of pollen is considered necessary for the dispersal by wind, and limited plants (resurrection plant) acquire desiccation tolerance in the vegetative growth. Desiccation/drought tolerance is the result of a dynamic process and appears to be mediated by the protective systems that prevent lethal damage. It also the result of the cooperation of physiological and biochemical alterations at the cellular and molecular levels, for example, the accumulation of various osmolytes and soluble sugars, late embryogenesis abundant proteins, efficient antioxidant systems in seeds and pollens. We have been using Saleginella tamariscina, a native lower vascular plant, as material to investigate the mechanism of desiccation tolerance.

The knowledge of regulatory genes and an understanding of their mode of action will provide an important starting point for the improvement of crop plants to face the abotic environment. The discovery and use of new stress-tolerance-associated genes to confer plant stress tolerance has been the subject of ongoing efforts internationally to obtain tolerant plants.
Studies demonstrated the important role of transcription factors in the acquisition of stress tolerance. Currently, we direct our attention to characterize the function of the AtDS1, AtERF53, AtERF1 and AtAIL7 all belonging to the AP2/ERF family. They either play as a positive or negative regulator of drought and salt stress response.? For example, we found AtDS1 overexpressors are sensitive to dehydration. ABI1 might act as an upstream gene of AtDS1, and can activate the expression of AtDS1 in the presence AtHB6 (see the figure below). The gene expression level of ABI2 was influenced by the expression level of AtDS1. ABI2 might be a direct target of AtDS1. Since no AP2/ERF protein binding cis-element was found in the ABI2 promoter, there must be a new cis-element in the promoter of ABI2 for the binding of AtDS1. These results suggest that AtDS1 is a linker between ABI1 and ABI2, and play a role under drought stress and ABA treatment.
We are also interested in glutathione S-transferase U17 which play a negative regulatory function in the drought/salt stress tolerance in Arabidopsis. The surprisingly discovery of GSTU17 plays a new function in drought/salt stress drives us to screen all the GSTU knockout mutants. We hope to find interesting gene and further characterize their function in abiotic stress.
