Abstract:
The luxA and luxB structural genes of Vibrio harveyi luciferase [alkanal,reduced FMN:oxygen oxidoreductase (1-hydroxylating, luminescing), EC 1.14.14.3] were introduced into a plant expression vector and transferred into tobacco and carrot cells by Agrobacterium-mediated or direct DNA transformation. Simultaneous expression of the luxA and luxB genes was monitored by protein immunoblot analysis. Luciferase-mediated light emission provided evidence for the assembly of the two protein subunits into a functional dimeric enzyme in plant protoplasts, in transformed calli, and in leaves of transformed plants. Bacterial luciferase may provide a useful marker-gene system for the quantitative assay of coordinate gene expression in transgenic plants.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
