Abstract: The present invention is drawn to the production of fertile transformed wheat plants. The method involved subjecting wheat tissues to high velocity microprojectile bombardment, selecting for transformed cells, and regenerating stably transformed fertile plants from the transformed cells.

Abstract: A linkage comprising an elongated rod, a rod actuator to longitudinally reciprocate the rod, and a clip of flexible, resilient material connecting the rod to the actuator. The clip has a circular hub rotatably received in an opening in the actuator. The rod has a hook at one end received in a hole in the hub of the clip. The hole is elongated to enable the rod to be axially rotated to facilitate the insertion of the hook end in the hole during assembly. The clip has a stabilizing arm extending laterally from the hub. The rod is received in a transverse slot in the arm.

Abstract: A system for the manufacture of a CO.sub.2 powered dragster with a low-cost three axis machine tool, the system including an expansion base to be fixedly secured to a support surface of the machine tool, and an indexing fixture to be adjustably secured to the expansion base. The indexing fixture has a generally elongate indexing plate which slides within the expansion base and is secured in one of at least two linear indexing positions, thereby positioning a portion of a material block from which a chassis of the dragster is made within a range of linear motion of the spindle, while a remaining portion of the material block is maintained aligned for subsequent positioning with the range of linear motion of the spindle, a rear end housing secured to a rear end of the indexing plate, and a front end housing secured a front end of the indexing plate.
