A transport device includes an abutting member that abuts a leading end of a transport object and transport members that are disposed upstream of the abutting member in a transport direction and transport the transport object to the abutting member. Laser light is both substantially generated and propagated in an alkali gas instead of a solid, allowing the nonlinear and damage limitations of conventional solid core fibers to be circumvented. The methods disclosed herein comprises transforming a plant cell to comprise the DNA constructs of the present invention, regenerating the plant cell into a plant and identifying independant transgene loci, where the selectable marker genes or transgenic elements can be segregated in the progeny.
