An article of footwear includes an upper with a heel region that extends posteriorly about the heel, a medial side, and a lateral side. The memory control module is configured to control access to the memory. Also disclosed are methods of producing transgenic monocot seed from the transgenic plants. The methods involve detection of 2-methoxyestradiol, or a precursor or metabolite thereof.
