| Course objective : | Plant species continually sense a myriad of signals such as environmental endogenes, to which they respond by adjusting their growth and their development. Phytohormones, temperature, light, availability of water and nutrients, pathogenic or symbiotic micro-organisms are all examples which determine the architecture and physiology of the organism. What's more, cellular plasticity and the physiology of plants allows them to acclimatise to extreme environmental conditions.
This course will address different signalisation pathways both systemic and cellular (receptors, signalling mediators). Two examples will be looked at in depth: (i) the interaction and communication between plants and micro-organisms and (ii) flowering.
This themed week will integrate the most cutting-edge knowledge concerning various aspects of signalling pathways and will enable students to understand the diversity of plant signalling cascades leading to an adequate physiological response. |
|
| Prerequisites : | Plant physiology, supplementary cellular physiology and molecular physiology. |
|
| Organization : | Around fifteen hours of lectures plus twenty hours of practical work/demonstrations to which discussion of articles will also be added. A minimum of 3 students are required for the week's course to take place. |
|
| Written notes : | Copy of Powerpoint slides. |
|
| Assessment : | Assessment methods will be determined between the students and the teaching staff. The exam could consist in presentation of an article on the last day of the week of the course. |
