Compositions and methods for anti-transpiration in plants
Methods and compositions comprising design of enlarged pectins are provided. Elaborated pectins are useful for a multitude of functions including surface coating, penetrant, additive and gell. Methods according to the present invention comprise steps for treatments to one or more live pectic cells in one or more compositions that result in modified pectins. In specific embodiments, methods are provided for applying the nanotechnology to live cells for carriage and incorporation of polar compounds.
1. A living plant having at least one molecule of pectin modified with a saccharide by subjecting said pectin to a Ca2+-chelation with a water-soluble salt of a Ca2+-chelator-saccharide-chelant selected from the group consisting of Ca2+-manganese-(NH4)2EDTA-acylglycosamines; Ca2+-manganese-(NH4)2EDTA-polyacylpolysaccharides; and Ca2+-manganese-(NH4)2EDTA-polyalkylpolysaccharides; and salts thereof.
2. A living plant having at least one molecule of pectin modified with a saccharide by subjecting said pectin to a Ca2+-chelation with a water-soluble salt of a Ca2+-chelator-saccharide-chelant, wherein the saccharide moiety of said Ca2+-chelator-saccharide-chelant is selected from the group consisting of a tetraalkylglycopyranose, a tetramethylglycoside; a tetramethylglycosamine, a tetramethylglucopyranose; methyltriacetyl glucoside, a triacetylglycopyranose; a tetraacetylglycopyranose; a tetraacetylglucopyranose, a triacetylglucopyranose; a tetraacetylmannopyranose, a triacetylglycopyranose, a tetraacetylglycopyranose, a tetraacetylglucopyranose, a triacetylglucopyranose, a tetraacetylmannopyranose and salts thereof, and wherein said chelator is EDTA.
3. The plant of claim 2 , wherein said alkylglycopyranose is a methyl glucopyranoside.
4. The plant of claim 2 , wherein said tetraalkylglycopyranose is a tetramethylglycopyranose.
5. The plant of claim 1 , wherein said Ca2+-manganese-(NH4)2EDTA-polyacylpolysaccharide comprises a polyacylpolysaccharide selected from the group consisting of disaccharides and oligosaccharides; and where the acyl group of said polyacylpolysaccharide is selected from the group consisting of acetyl n where n is from 2 to 5, and glycosamineAcetyl n where n is from 2 to 5; and where the saccharide group of said polyacylpolysaccharide is selected from the group consisting of galactose, glucose, mannose and combinations thereof.
6. The plant of claim 1 , wherein said Ca2+-manganese-(NH4)2EDTA-acylglycosamines comprise acylglycosamines selected from the group consisting of acylmannosamines, acylglucosamines, acylgalactosamines and disaccharide, oligosaccharide, and polysaccharide derivatives thereof.
