Abstract
The invention relates to a method for increasing the yield and biomass of a plant, by means of an increase in the expression of the L-aspartate oxidase in the plant. The method according to the invention allows an increase in the photosynthetic capacities of the plants as a result of an increase in the quantities of NAD and the derivatives thereof in said plants. The invention relates to the plants produced by such a method.
Claims16
A method for improving at least one phenotypic trait of a plant, said method comprising introgression of a nucleic acid sequence into the plant, wherein the nucleic acid sequence comprises a sequence encoding L-aspartate oxidase and comprises an exogenous promoter functionally linked to the sequence encoding L-aspartate oxidase,
- wherein the at least one phenotypic trait is one or more selected from the group consisting of biomass, yield, abiotic stress resistance, biotic stress resistance, germination rate and growth rate,
- wherein the nucleic acid sequence is present in a genome,
- wherein the resulting plant overexpresses L-aspartate oxidase, and
- wherein the overexpression of L-aspartate oxidase leads to increased amounts of NAD and derivatives thereof,
- wherein the sequence encoding L-aspartate oxidase comprises SEQ ID NO:
- 1.
A method for producing a plant exhibiting at least one improved phenotypic trait, comprising detection of the presence of a genetic element, linked to overexpression of L-aspartate oxidase in a donor plant, and transfer of the genetic element, linked to overexpression of L-aspartate oxidase in the donor plant thus detected, from the donor plant to a recipient plant,
- wherein the at least one phenotypic trait is one or more selected from the group consisting of biomass, yield, abiotic stress resistance, biotic stress resistance, germination rate and growth rate,
- and wherein the genetic element comprises SEQ ID NO:
- 1.
A method for improving at least one phenotypic trait of a plant, said method comprising introgression of a nucleic acid sequence into the plant, wherein the nucleic acid sequence comprises a sequence encoding L-aspartate oxidase and comprises an exogenous promoter functionally linked to the sequence encoding L-aspartate oxidase,

- wherein the nucleic acid sequence is present in a genome,
- wherein the resulting plant overexpresses L-aspartate oxidase, and
- wherein the overexpression of L-aspartate oxidase leads to increased amounts of NAD and derivatives thereof,
- wherein the sequence encoding L-aspartate oxidase comprises SEQ ID NO:
- 1.
