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 NAO and the derivatives thereof in said plants. The invention relates to the plants produced by such a method.
Claims9
A method for improving at least one phenotypic trait of a plant, said method comprising transforming the plant with a nucleic acid sequence, 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 seed yield, abiotic stress resistance, biotic stress resistance, germination rate, and growth rate, wherein the abiotic stress resistance comprises at least one of intense sunlight, lack of light, excess water, cold, or excessive heat,
- wherein the nucleic acid sequence is present in a genome,
- wherein the resulting plant overexpresses L-aspartate oxidase,
- wherein the overexpression of L-aspartate oxidase leads to increased synthesis of NAD and derivatives thereof, and
- wherein said sequence comprises SEQ ID NO:1 or a sequence with at least 80% identity to SEQ ID NO:1, with the proviso that the sequence having at least 80% identity is not SEQ ID NO:15.
