Plants/micro-organisms/artificial soil simplified ecosystem

Cel



This project is based on the study of the interaction plants / micro-organisms. Experiments will consist of an ultra-simplified model of ecosystem plant-artificial soil.

The first goal is to compare the growth of plants with and without micro-organisms inoculation, and with and without atmospheric CO2 enrichment. The second objective is to contribute to the understanding of the global changes in natural ecosystems and to overcome the problem of acclimatisation of plantlets after sterile in vitro culture.

Special attention will be paid to the evolution of populations of micro-organisms in response to CO2 enrichment, in parallel to the effect on plant growth and development. Identification and numeration of microbial populations will be performed, specifically associated with the roots of the studied plants and particularly stimulated by CO2 enrichment, whose presence, on its own, would be responsible for the observed effects.

Special attention will also be devoted to micro-organisms not known in classical symbiotic associations with plants and on microbes directly associated to the roots (rhizoplan).

The expected results from the study of the response to the atmospheric CO2 rise will be: to acquire the know-how of the plant-microbes association in simplified and controlled conditions; to repeat (Canadian) results showing a positive interaction between plant and microbes (in the absence of classical symbioses); to contribute to studies on global climate changes by comparing the response of plants alone or in association with microbes acting as a sink of assimilates and modifying the resulting effect of CO2 enrichment; and to make progress in applied methods using in vitro techniques and a non-axenic culture medium.
