Kinematics of seedling elongation
Kinematics of seedling elongation
Background: Après la germination, les plantes doivent grandir pour atteindre la lumière et déployer leur appareil photosynthétique. Cette croissance est d'abord alimentée par l'énergie contenue dans la graine. Les plantes doivent atteindre la lumière et déployer leurs cotylédons avant d'avoir épuisé l'énergie de la graine. L'étude de la dynamique de la croissance dans diverses conditions peut permettre de mieux comprendre le processus de croissance.
Upon germination, plants need to grow to reach the light and set up their photosyntethic apparatus. This growth is initially sustained by the limited energy resources available in the seed. This is a crucial process, as they have to reach the light and be able to produce their own energy before running out of energy. Insight into this process can be gained by a detailed investigation of the kinematics of growth in various conditions.
Goal: The goal of this project is to characterize and model the growth pattern of Arabidopsis seedlings in various light conditions. The student will first collect data using a software developed for that purpose (hypoPhen) and develop a mathematical model of hypocotyl elongation. They will try to investigate whether the data is in agreement with the model, and whether they can reproduce observations described in the scientific literature.
Mathematical tools: Ordinary differential equations and statistics
Biological or Medical aspects:
The students will learn about the regulation of seedling elongation.
