Nominator's project description
| Negative environmental influence causes stress for plants, resulting in crop failures – a problem that is probably being aggravated by climate change. The immediate response of plants to such influence has been well researched, unlike their adaptation to lasting or recurrent stress, although it is of considerable importance in nature. Plants are quite capable of remembering stressful situations and will respond to the reoccurrence of such situations. The basic molecular mechanisms involved here are largely unknown. With the “memory” of Arabidopsis (Thale Cress), Isabel Bäurle wants to demonstrate how plants store environmental influences at molecular level and generally develop a cellular memory although they lack a nervous system. She is investigating how this memory changes in the course of evolution to make plants adaptable to different habitats. The insights she hopes to obtain will also be of economic importance and could provide new approaches to optimising crop yields. |
