The invention relates to the use of phycobiliproteins or of an extract containing same as fertilizer, a method for stimulating tillering and/or root development and/or the yield of a plant, as well as fertilizer compositions comprising phycobiliproteins or an extract containing same and (i) an amendment and/or (ii) a fertilizer other than phycobiliproteins or an extract containing same.

Use of phycobiliproteins or an extract containing same as fertilizer

The invention concerns a medicine comprising, as active principle, an efficient quantity of at least an oligosaccharide substance capable of modulating apoptosis dysfunction which is capable of modifying apoptosis dysfunctions said substance being selected from the group consisting of oligosaccharides which are derived, by enzymatic or chemical process, from the polymers of the group comprising (1&rarr;3)-&bgr;-glucans which optionally comprise (1&rarr;6)-&bgr;-branching, and oligosaccharides which are derived, by enzymatic or chemical process, from sulfated galactans, it also concerns a method for treating apoptosis dysfunction.

Medicine for treating apoptosis dysfunction containing oligosaccharides

The present invention provides a method to potentiate and stimulate natural defensive reactions of plants to a pathogenic agent. The method comprises application to plants of a composition comprising an effective amount of one or more oligo &bgr; 1-3 glucans composed of 3 to 250 monosaccharide units and a vehicle, wherein the effective amount of oligo &bgr; 1-3 glucans in the composition does not directly stimulate natural defensive reactions of plants when the pathogenic agent is absent.
