Compositions and methods for the efficient transformation and regeneration of monocot plants are provided. The methods of transformation involve infection with Agrobacterium. In this manner, any gene of interest can be introduced into the monocot plant with high transformation efficiency and in low copy number. Transformed and regenerated monocot cells, tissues, plants, and seed are also provided. The invention encompasses regenerating transformed plants, transgenic seeds produced therefrom, and transgenic plants and transgenic seeds from subsequent generations.
