SUMMARY:Special Seminar: Dr.  Daniel Kierzkowski
DESCRIPTION:How are leaf shapes generated?











A Special Seminar with Dr. Daniel Kierzkowski



Université de Montréal



A current challenge in biology is how multi-cellular organisms generate their shapes. Although the genetic basis of morphogenesis is relatively well characterized, it is still unclear how gene action translates into biological shapes. We try to answer this fundamental question by using a combination of genetic, confocal time-lapse imaging, 3D-image analysis, and computational modeling. As an example of this quantitative approach, I will present our recent results on leaf morphogenesis in two closely related species Arabidopsis thaliana, which has simple leaves with serrations, and Cardamine hirsuta with compound leaves subdivided into individual leaflets. I will show how leaf forms and proportions can be modulated by the fine-tuning of growth, patterning, and cell differentiation within mechanically connected plant tissue.
