Abstract
Disclosed is an application of SDG40 gene or an encoded protein thereof. Specifically, when the expression of SDG40 gene or an encoded protein thereof is inhibited, agronomic traits of crops can be significantly improved, which include: (i) improved low light utilization efficiency (A low); (ii) increased biomass; (iii) increased number of tillers; (iv) increased yield per plant; and/or (v) increased plant height. In addition, it was also found that a mutation of the promoter region of the SDG gene from C to T and/or a mutation to from A to C can also significantly improve the low light utilization efficiency (A low) of crops.
Claims10
A method of regulating an agronomic trait of a plant, comprising the steps of administering an inhibitor of SDG40 gene or encoded protein thereof to a plant, wherein the agronomic trait of the plant is selected from one or more of the following groups:
- (i) low light utilization efficiency (Alow);
- (ii) biomass;
- (iii) the number of tillers;
- (iv) yield per plant;
- (v) plant height.
A method for improving an agronomic trait of plant, comprising the steps:
- reducing the expression level or activity of the SDG40 gene or the encoded protein thereof in the plant, thereby improving the agronomic trait of the plant.
A method for improving the low light utilization efficiency (Alow) of a plant, comprising the steps of:
- reducing the expression of a SDG40 gene or an encoded protein thereof in the cell or plant, or mutating the C in the promoter region of the SDG40 gene in the plant to T and/or mutating A to C, thereby improving the low light utilization efficiency (Alow) of the plant.
