Definitions
- the present invention relates to a method for increasing the resistance of plants to abiotic stress, particularly cold or water stress, by foliar spraying a composition based on xyloglucan.
- the cell walls of fruits and vegetables are formed of polysaccharides, mainly pectin, cellulose and xyloglucan which is involved in the placement of walls (Levy S et al., Plant J. 1997, 11 (3): 373 -86). Xyloglucan is also found in large quantities in the endosperm of Dicotyledonous seeds.
- Xyloglucan is a polymer of 1,4- ⁇ -glucan substituted differently depending on its origin. In Dicotyledonous, substitutions of 1,4- ⁇ -D-glucan linear chains most often involve 1.6- ⁇ -D-xylosyl, or
- D-xylose 1,2- ⁇ -D-galactosyl, and fucose may be associated, in the terminal position, with galactose, a lateral branching of the type 1,6 ⁇ -D-xylose 1,2 ⁇ -D-galactose 1, 2 ⁇ -L-fucosyl. Still in the dicotyledons, the fucose residue is absent from the endosperm, and it can be replaced by the ⁇ -L-arabinose residue, for example in some Solanaceae. Monocotyledonous xyloglucan differs from that of Dicotyledonous by a lower rate of substitution by xylose, galactose and no fucose residues.
- Xyloglucan forms with the cellulose microfibers bridged structures that constitute the structure and ensure the flexibility of the plant cell wall (Pauly M 5 Albersheim P, Darvill A 5 York WS (1999) Plant J, 20 (6): 629 -39).
- Xyloglucan is a substrate of endoxyloglucanases (Vincken JP, Beldman G,
- Xyloglucan in particular a fucosylated oligomer, the nonasaccharide XXFG (described in Fry et al (1993) Physiologia Plantarum, 89, 1-3), is well known for its anti-toxic effect (Mac Dougall CJ and Fry SC (1989) Plant Physiol 89, 883-887).
- oligomers without fucose but with galactose such as oligomers XXLG and XLLG have auxinic effect (Mc Dougall GJ and Fry SC (1990) Plant
- Activated oxygen species particularly superoxide, control different metabolic pathways. They intervene in:
- oxidases are involved in the regulation of gibberellin biosynthesis.
- Activated oxygen species are involved in signal transduction steps because they are associated with receptor binding activity or transducing enzyme activity (Jabs T, Chole M, Colling C, Hahlbrock K and Scheel D (1997) Proc Natl Acad Sci USA 29, 94, 9, 4800-4805, Durner J, Wendehenne D, Klessig DF (1998) Proc Natl Acad Sci USA, 95, 10328-10333). They intervene in the regulation of the cellular redox potential via the thiol groups (conversion GSSG-GSH, cystine-cysteine, etc.). As such, they control processes of senescence that occur at certain stages of flowering and fruiting in different organs.
- the oxidative burst interferes with the hormonal metabolism, the best potential to regulate the stages of flowering and fruiting (in particular their release and their duration are programmed by a hormonal balance (auxin ratio / cytokinin for example), and the activated species of oxygen, including peroxide, control the synthesis of polyamines).
- a hormonal balance auxin ratio / cytokinin for example
- the activated species of oxygen including peroxide, control the synthesis of polyamines.
- polymers and oligomers of xyloglucan in particular compounds comprising a saccharide structure of formula XFG 3 as well as compounds derived from these, have a stimulating effect.
- these compounds trigger adaptation reactions to any oxidative stress, such as cold in particular, by limiting the toxic effects of activated species of oxygen (Allen RD, Webb RP, Schake SA (1997) Free Radie Biol Med, 23 (3): 473-479, O'Kane D, GiI V, Boyd P, Burdon R (1996) Planta, 198 (3): 371-377), and they regulate the redox potential of the cell, which modifies the activity of enzymes or thiol-dependent proteins, phospholipase D, thiol protease and thiol protease inhibitors in particular (Taher MM, MA Mahgoub 5 Abd-Elfattah (1998) Biochem Mol Biol Int aS 3, 619-28), as well as by an induction effect of a thiol-dependent protease inhibitor, and without cascading other enzymatic systems in proportions that are detrimental to the plant.
- activated species of oxygen Allen RD, Webb RP, Schake SA (
- these compounds By stimulating the phospholipase D activity, these compounds amplify the hormonal effect of abscisic acid insofar as the activation of the enzyme leads to the production of phosphatidic acid (which mimics the effects of abscisic acid) . As such, they may reveal antagonism against gibberellins, ethylene or jasmonates (Grill E., Himmelbach A. (1998) Current Opinion in Plant Biology, 1, 1, 5, 412-418;
