【Report】Interactions between plant development and climate change
2016-09-24 14:20  

Topic】:Interactions between plant development and climate change 

Time】: 08:30am-10:00am, September 28th, 2016

Venue】:D05-209

Lecturer】:Professor Astrid Wingler

Abstract】:

   Climate change and elevated carbon dioxide concentrations have a direct impact on plant developmental events, such as leaf formation, flowering and leaf senescence. During leaf senescence photosynthesis declines and nutrients, such as nitrogen, are recycled from the old leaves. These nutrients can be used for the growth of new leaves or for the formation of seeds. Importantly, changes in the timing of leaf formation and senescence affect photosynthetic carbon dioxide fixation and therefore have a direct impact on future climate change. The lecture will focus on the interactions between climate change and leaf senescence, and explain the consequences for agriculture and forestry.

Research Interests

My research focuses on the role of sugar signalling in plant development and in the perception of environmental signals. For example, my group exploits natural genetic variation to investigate the genetic basis and molecular mechanisms that regulate leaf senescence. Most of this research is conducted with the model species Arabidopsis, but we also use a perennial relative of Arabidopsis, Arabis alpina, to explore how senescence is regulated by environmental conditions in perennial plants. In addition, I am interested in the pathways that determine plant growth in response to temperature, for example in perennial grasses.
