We are interested in understanding how environmental changes cause adjustments in plant growth, aging and death as well as the metamorphosis from cell growth to cell death using multidisciplinary approaches, including systems-level analysis, genetics, cell and molecular biology. Our studies will help to predict physiological and genetic changes in plants during the plant’s lifespan that global climate change causes, and also aid in preparing for the future ecological reshaping.
Abscission includes a series of separation events in which entire organs such as leaves, fruit, or floral organs are shed, which takes an important part as the terminal phase of senescence. The timing and intensity of organ shedding are directly linked to fruit yields and numerous efforts have been made throughout history of agriculture to control the abscission process. While much progress has been made to identify important regulators of the abscission processes, our knowledge of the underlying mechanisms is still far from the complete view, and little is known as to how developmental and environmental cues are integrated into the abscission processes. Research in our group aims at elucidating cellar and molecular mechanisms of abscission, provides a better understanding of signaling networks regulating abscission, and establishes the abscission zone as a model system for facilitating studies of plant senescence at the cellular level.
