Abstract: A collapsible watercraft for personal recreation. The collapsible watercraft includes a tubular frame that has a first portion and a second portion. Each of the portions are generally rectangular and are hingably coupled together allowing them to be folded one portion on top of the other. Two sets of pairs of floatation members are hingably mounted to the frame and are positionable between being adjacent the outer side of the frame for use, and adjacent the inner side of the frame for storage or transit. An human-powered oscillation of a fin member propels the craft. The fin member also serves as a rudder for steering. A foldable seat with a backrest along with a cargo net behind the seat is provided. A canopy is mountable to the frame for protection of the user from the elements.

Abstract: There are described 5' transcriptional regulatory regions of plant genes which ensure sink organ specific expression of cis-linked DNA sequences as well as recombinant double stranded DNA molecules comprising these 5' regulatory regions. Furthermore the present invention relates to a method for producing transgenic plants which show a sink tissue specific expression of a desired DNA sequence.

Abstract: There is described a new DNA sequence of an expression cassette on which the potato tuber specific regulatory regions are localised as well as the transfer of this DNA sequence into the plant genome using agrobacteria as transfer micro-organisms. The DNA sequence contains a patatin gene with a patatin gene promoter. The transfer DNA sequence acts both for regulating endogenous as well as for preparation of heterologous products in crops.
