The invention concerns endofucanases suitable for preparing fuco-oligosaccharides by enzymatic hydrolysis of fucanes. It also concerns a bacterium producing endofucanases and the preparation of said enzyme from the bacterium. It further concerns endofucanase genes and it finally concerns the use said fuco-oligosaccharides for plant protection.

Endofucanases and method using same for preparing fuco-oligosaccharides from fucanes, bacterium producing endofucanases and uses of fuco-oligosaccharides for plant protection

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.
