NOVELTY - A regulatory polynucleotide molecule isolated or identified from Oryza sativa, or its complement, fragment, or cis element, where the polynucleotide molecule functions to regulate the activity of the MTH gene, is new.    USE - The polynucleotide and construct are useful for developing transgenic plants with desired traits, e.g. herbicide tolerance, insect control, modified yield, fungal disease resistance, virus resistance, nematode resistance, bacterial disease resistance, improved plant growth and development, improved starch production, modified oils production, high oil production, modified fatty acid content, high protein production, improved fruit ripening, enhanced animal and human nutrition, environmental stress resistance, improved processing traits, and improved digestibility, enzyme production, flavor, nitrogen fixation, hybrid seed production, fiber production, or biofuel production (all claimed).    ADVANTAGE - The present invention provides new regulatory elements, such as promoters, that are capable of expressing heterologous nucleic acid sequences in important crop species. The promoters exhibit both constitutive expression and tissue-specific patterns needed in the development of plants that exhibit agronomically desirable traits.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are:    (1) a chimeric molecule comprising the regulatory polynucleotide molecule;    (2) a polynucleotide construct comprising the regulatory polynucleotide molecule, where the regulatory polynucleotide molecule is operably linked to a transcribable polynucleotide molecule;    (3) a transgenic plant cell stably transformed with the polynucleotide construct of (2);    (4) a transgenic plant stably transformed with the polynucleotide construct of (2);    (5) a seed of the transgenic plant of (4);    (6) a progeny of the plant of (4); and    (7) a method of inhibiting weed growth in a field of transgenic glyphosate-tolerant crop plants by planting the transgenic plants transformed with an expression cassette comprising (i) a regulatory element polynucleotide molecule isolated or identified from the rice metallothionein gene, active in a plant cell and operably linked to a polynucleotide molecule encoding a glyphosate tolerance gene, and (ii) applying glyphosate to the field at an application rate that inhibits the growth of weeds, where the growth and yield of the transgenic crop plant is not substantially affected by the glyphosate application.
