V: Construction and modeling of plant hormones networks
It has been found that many biological processes are coordinately regulated by multiple hormones. We have built an Arabidopsis Hormone Database (AHD: http://ahd.cbi.pku.edu.cn/) by integrating a large body of experimental data and computational annotations. The aim of the Arabidopsis hormone database is to provide a systematic and comprehensive view of morphological phenotypes and regulatory genes participating in numerous plant hormone responses. In the future, we will generate an atlas of plant hormone biology, and make theoretical models to describe, verify and predict the functions and actions of plant hormones.

VI: Hormonal regulation of plant ageing
Plant ageing is quite distinctive and unique compared to animal or human ageing. The proper control of plant ageing programs (such as leaf senescence, flower senescence) has tremendous potential for agricultural good and thus is of great interest to scientists in recent years. The leaf senescence is the final developmental phase of a plant leaf, which is influenced by several phytohormones, with cytokinin and ethylene having the most important roles in delaying or inducing leaf senescence, respectively. Currently we are interested in uncovering the regulatory mechanisms of ethylene and cytokinin on leaf senescence. Also, we have recently built a Leaf Senescence Database (LSD: http://www.eplantsenescence.org/), and attempt to study leaf senescence in a more systematic way.
