Abstract
Genome edited plants, plant cells, seeds and plant parts of maize are provided where expression levels and/or activities of MADS-box transcription factors are modulated to improve one or more agronomic characteristics such as grain yield. Also provided are compositions comprising polynucleotides encoding polypeptides and guide RNAs targeted to endogenous maize MADS-box proteins including for example, targeted site-directed mutagenesis using CRISPR-associated nucleases. Additionally, various methods of employing the polynucleotides and genetic modifications in plants, such as methods for modulating expression level in a maize plant and methods for increasing yield of a maize plant are also provided herein.
