Abstract
A method for increasing fungal resistance in a plant, a plant part, or a plant cell wherein the method comprises the step of increasing the production and/or accumulation of scopoletin and/or a derivative thereof in the plant, plant part, or plant cell in comparison to a wild type plant, wild type plant part, or wild type plant cell.
Claims17
A method for reducing, preventing, or delaying biotrophic rust fungal infection in a plant, a plant part, or a plant cell, said method comprising:
- providing a transgenic plant, transgenic plant part, or transgenic plant cell with an exogenous nucleic acid encoding an F6H1 protein having an amino acid sequence with at least 90% identity to SEQ ID NO:
- 2, wherein the F6H1 protein increases the production and/or accumulation of scopoletin and/or scopolin in the plant, plant part, or plant cell in comparison to a wild type plant, wild type plant part, or wild type plant cell;
- and
- growing the transgenic plant, transgenic plant part, or transgenic plant cell in the presence of a biotrophic rust fungus, wherein biotrophic rust fungal infection is reduced, prevented, or delayed in the transgenic plant, transgenic plant part, or transgenic plant cell as compared to a wild type plant, wild type plant part, or wild type plant cell.
A transgenic plant, transgenic plant part, or transgenic plant cell comprising an exogenous nucleic acid encoding an F6H1 protein having an amino acid sequence with at least 90% identity to SEQ ID NO:
- 2, wherein the F6H1 protein increases the production and/or accumulation of scopoletin and/or scopolin in the plant, plant part, or plant cell in comparison to a wild type plant, wild type plant part, or wild type plant cell and results in increased resistance to biotrophic rust fungal infection, and wherein the transgenic plant, transgenic plant part, or transgenic plant cell is selected from the group consisting of beans, soya, pea, clover, kudzu, lucerne, lentils, lupins, vetches, and groundnut.
