Methods and compositions for modulating plant growth, strength and flexibility are provided. Nucleotide sequences encoding maize expansin proteins are provided. The sequence can be used in expression cassettes for modulating growth, stalk strength and flexibility. Transformed plants, plant cells, tissues, and seed are also provided. Methods for rapidly identifying and isolating a Mu-tagged recessive gene mutation in a F1 generation plant, and identification and isolation of its associated wild-type gene are also provided.
