IMPROVEMENT OF IN VITRO PLANT CULTURES AT LABORATORY AND INDUSTRIAL SCALES :CONTROL OF GASEOUS ENVIRONMENT BY USING SELECTIVE MEMBRANES AS LIDA OF CULTURE CONTAINERs

Objective


2 outstanding and unresolved problems exist in in vitro plant micropropagation techniques. The lack of knowledge about the composition of the inner gaseous environment of containers and its influence on the physiological behaviour of vitroplants, and the lack of an automated process to reduce the high level of the cost of in vitro techniques.
The following subjects have been addressed:
analysis of the gas phase in containers implanted with vitroplants;
analysis of selective permeability of membranes and adjustment to tissue culture;
development of a disposable plastic container with selected membranes;
biological assays with vitroplants until the acclimatisation phase and scale-up.
Two outstanding and unresolved problems exist with in vitro plant micropropagation techniques. These are a lack of knowledge about the composition of the inner gaseous environment of containers and its influence on the physiological behaviour of vitroplants, and the lack of an automated process to reduce the high level of the cost of in vitro techniques.

The project will respond to these problems using the following approaches.
A detailed analysis of components of the gas phase inside containers.
The control of the gas phase by using membranes with a selective permeability to gases. Tests of selectivity of membranes, feasibility of technical process for using membranes as lids of containers and for developing a disposable cheap container, will be performed.
Biological assays using the normal containers will be performed with choice of different membranes and permeabilities in different culture conditions (gelled and artificial substrates, solid and liquid nutrient media). A large spectrum of plant species (Gymnosperms, Angiosperms, Monocots, Dicots, herbaceous, and woody plants) and plant tissue cultures forms will be tested.
If the results are consistent with the objectives, many applications would be available in the wide field of in vitro techniques of plant micropropagation.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.
