The application describes producing polynucleotide variants of the AtHB 17 clade members and introducing the mutant variants into plants to improve plant traits. The mutant polynucleotides encode polypeptides that comprise mutations in the EAR motifs.

Mutation of the EAR motif of class II HD-ZIP polypeptides

This disclosure provides transgenic plants, including crop plants and methods for their production. The transgenic plants comprise recombinant DNA constructs for the expression of polypeptides encoded by the DNA constructs. The polypeptides are capable of conferring improved traits to the transgenic plants when expressed under the control of a tissue-enhanced promoter. This disclosure also pertains to transgenic plants and their progeny plants, wherein the transgenic or progeny plants comprise the recombinant DNA constructs and are selected for having enhanced nitrogen use efficiency and/or nitrogen uptake. Seed of the transgenic plants that can be grown into a plant that comprise the disclosed recombinant DNA constructs and exhibits having enhanced nitrogen use efficiency, and which may be selected for this trait, are also envisioned.
