Abstract: The present invention discloses a protein regulating nitrogen-use efficiency and yield of a plant and the use thereof. The present invention obtains a transgenic OsTCP19 rice and a rice OsTCP19 mutant by means of a transgenic technique and a CRISPR-Cas9 technique, respectively. Experiments have shown that compared with wild-type rice, the transgenic OsTCP19 rice has a reduced tiller number and a decreased nitrogen response ability, whereas compared with the wild-type rice, the rice OsTCP19 mutant has an increased tiller number. This indicates that the OsTCP19 protein has the function of regulating the plant yield and nitrogen-use efficiency, thus laying the foundation for cultivating varieties with a high yield and a high nitrogen-use efficiency.

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.

Abstract: Methods and compositions that affect yield and other agronomic characteristics in plants are disclosed. Methods of transgenic modulation and marker-assisted breeding methods improve grain size and grain yield in rice are also disclosed. Increased expression of BG1 results in increased grain size and yield.

Abstract: The present invention describes a method of increasing plan yield. Also described are DNA constructs comprising DNA sequences coding for proteins involved in sucrose transport, metabolism and uptake operably linked to controllable promoter regions and plants transformed with said constructs. More particularly a method for the controlled production of said proteins resulting in an alteration in plant growth characteristics, flowering time and in yield is described.
