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

Polynucleotides and polypeptides incorporated into expression vectors are introduced into plants and were ectopically expressed. These polypeptides may confer at least one regulatory activity and increased yield, increased resource use efficiency, increased water use efficiency, increased light use efficiency, increased photosynthetic capacity, increased photosynthetic rate, increased photosynthetic resource use efficiency, greater vigor, and/or greater biomass as compared to a control plant.
