Provided are an isolated polynucleotide encoding a ICDH1 polypeptide, use of the isolated polynucleotide in a plant to regulate the flowering time, to promote early flowering time or to promote delayed flowering, and to increase nitrogen stress tolerance or NUE, a recombinant DNA construct comprising the isolated polynucleotide, a modified plant or seed comprising an increased expression of a polynucleotide encoding a ICDH1 polypeptide, as well as the application thereof in the methods for increasing drought tolerance in a plant, for enhancing grain yield in a rice plant, for making a plant, and for identifying one or more alleles associated with increased grain yield in a population of rice plants. |
