Abstract

A fusion gene usingluxA andluxB genes ofVibrio species has been designed to express light autonomously in plants.LuxA:luxB was introduced into plants by a high-efficiency transformation system consisting of a high-copy virulence helper plasmid pUCD2614 and T-vector pUCD2715 containingluxA:luxB. The expression ofluxA:luxB fusion gene was optimized by adjusting the spacing between the genes and by placing the translational efficiency of its mRNA under the control of the Ω-3 translational enhancer. The resulting transgenic plants synthesized luciferase at levels greater than 1% of the total leaf protein. These plants produced light autonomously and light intensity was enhanced by the addition of aldehyde. That theluxA:luxB fusion has been optimized enables its use as a reporter for gene activity in plants during development and under various stress-inducing conditions. These results show that a specific protein from an introduced foreign gene can be produced with high efficiency in cultivated plants and such a system is therefore amenable for production of desired proteins through conventional farming methods.
