Abstract
The present invention relates to plants having resistance to PPO inhibiting herbicides such as the herbicide oxyfluorfen conferred by a loss of function of one or more sulfolipid biosynthesis enzymes involved in the sulfolipid biosynthesis pathway and methods of producing said plants. The invention also relates to methods of producing a plant having resistance to PPO inhibiting herbicides, including but not limited to the herbicide oxyfluorfen, by modulating the expression of one or more sulfolipid biosynthesis genes and/or function of one or more sulfolipid biosynthesis enzymes involved in the sulfolipid biosynthesis pathway, and to plants produced by the methods.
Claims15
A plant having non-transgenic resistance to PPO inhibiting herbicides.
A plant, plant part thereof, or seed having resistance to PPO inhibiting herbicides, wherein said resistance is conferred by a loss of function of a sulfolipid biosynthesis enzyme involved in the sulfolipid biosynthesis pathway.
A method for producing a plant having resistance to PPO inhibiting herbicides comprising modulating the expression of a gene encoding a sulfolipid biosynthesis enzyme in a plant, wherein said gene is UGP3, SQD1, or SQD2, or homologs thereof, and wherein the modulation of expression of said gene results in a loss of function of the sulfolipid biosynthesis enzyme UGP3 enzyme UGPase, SQD1 enzyme UDP-sulfoquinovose synthase, or SQD2 enzyme SQDG synthase, or homologs thereof, and wherein said plant exhibits increased resistance to PPO inhibiting herbicides as compared to a wild type plant.
A method for producing a PPO inhibiting herbicide resistant plant, wherein the sequence of the gene UGP3, SQD1, or SQD2, or homologs thereof, is used to induce or select for loss of function of the sulfolipid biosynthesis pathway in the plant.
