A vehicle driving force control apparatus is provided to prohibit a change in a shift schedule that will cause insufficient power generation of a generator that supplies power to an electric motor to drive a first drive wheel. The system comprises a base, a motion stage movably provided to the top of the base, and first to sixth feeding mechanisms for moving the motion stage to have six degrees of freedom. The invention further relates to methods for producing a lettuce plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other lettuce lines derived from the cultivars SCARAMANGA, GIMLET, SPRITZER andor MOJITO. In the case of a commercial unit having a printing substrate that has been only partially printed during a production run of the printing press, the data set can be supplemented with data which, at least, characterizes an event.
