Abstract
Methods for modulating levels of at least one organic sulfur compound in plants are provided. Also provided are plants and seeds produced by the methods. The methods comprise stably transforming a plant with a DNA construct encoding a cystathionine gamma synthase enzyme, a serine acetyl transferase enzyme and/or other sulfur assimilating enzymes capable of altering the level of at least one organic sulfur compound.
Claims21
A method for modulating biosynthesis of at least one organic sulfur compound in the seed of a monocotyledonous plant, the method comprising stably transforming the plant with a DNA construct comprising a nucleic acid encoding a plant cystathionine gamma synthase nucleic acid, wherein the nucleic acid is operably linked to a non-seed preferred promoter that drives expression in the plant and wherein the level of the at least one organic sulfur compound is altered.
A monoctyledonous plant with seed having increased levels of at least one organic sulfur compound, the plant having stably transformed into its genome a DNA construct comprising a nucleic acid encoding a plant cystathionine gamma synthase nucleic acid, wherein the nucleic acid is operably linked to a non-seed preferred promoter that drives expression in the plant.
A method for modulating biosynthesis of at least one organic sulfur compound in the seed of a monocotyledonous plant, the method comprising stably transforming the plant with a DNA construct comprising a nucleic acid encoding a plant serine acetyl transferase nucleic acid, wherein the nucleic acid is operably linked to a non-seed preferred promoter that drives expression in the plant and wherein the level of the at least one organic sulfur compound is altered.
A monoctyledonous plant with seed having increased levels of at least one organic sulfur compound, the plant having stably transformed into its genome a DNA construct comprising a nucleic acid encoding a plant serine acetyl transferase nucleic acid, wherein the nucleic acid is operably linked to a non-seed preferred promoter that drives expression in the plant.
