Abstract: Provided herein is a novel truck bed mounted rack which advantageously combines the ability to transport or store cargo in one configuration while establishing a framework for a sheltered, spacious environment in the other configuration. The expandable truck rack system of the invention combines useful functions of racks, tonneaus and roof tents into a single universal solution.

Abstract: The invention discloses methods of controlling one or more genes in plants. The genes may be exogenous genes and produce a desired phenotypic trait in the plants produced. The genes are operatively linked to a heterologous upstream activating sequence (UAS) recognition site, which is activatable by a transactivating protein. The genes linked to the UAS sequence, and nucleic acid encoding for the transactivating protein may originally be in separate transgenic plants, one of which fertilizes the other to produce reproductive material, such as seed, which may be grown into plants expressing the desired phenotype. The desired phenotype may be herbicide resistance or the production of a polyhydroxyalkanoate, such as polyhydroxybutyrate.

The genes are operatively linked to a heterologous upstream activating sequence (UAS) recognition site, which is activatable by a transactivating protein, such as GAL4. The genes linked to the UAS sequence, and nucleic acid encoding for the transactivating protein may originally be in separate transgenic plants, one of which fertilises the other to produce reproductive material, such as seed, which may be grown into plants expressing the desired phenotype. The desired phenotype may be herbicide resistance or the production of a polyhydroxyalkanoate, such as polyhydroxybutyrate.
