Abstract
The present invention relates to the method and use of reef coral fluorescent proteins in making transgenic red, green and yellow fluorescent zebrafish. Preferably, such fluorescent zebrafish are fertile and used to establish a population of transgenic zebrafish and to provide to the ornamental fish industry for the purpose of marketing. Thus, new varieties of ornamental fish of different fluorescence colors from a novel source are developed.
Claims19
A method of making a transgenic fluorescent fish progeny comprising the steps:
- (a) selecting a first transgenic fluorescent fish comprising a first transgene encoding a first fluorescent protein, and a second transgene encoding a second fluorescent protein;
- and
- (b) breeding the first transgenic fish with a second fish to make a transgenic fluorescent fish progeny, wherein the transgenic fluorescent fish progeny comprises in its genome:
- (i) the first transgene encoding the first fluorescent protein, wherein the first transgene is under the control of a muscle specific promoter, and
- (ii) the second transgene encoding the second fluorescent protein, wherein the second transgene is under the control of a ubiquitous fish promoter;
- wherein the first and second transgene encode different fluorescent proteins, and wherein the transgenic fluorescent fish progeny visibly expresses a fluorescent color different from the color encoded by the first transgene and the second transgene, and wherein the transgenic fluorescent fish progeny exhibits a strong visible fluorescence over 75% to 100% of the body of said fish, optionally excluding fins and eyes, wherein at least one of the first and second transgene comprises a nucleic acid sequence selected from the group consisting of SEQ ID NO:
- 1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, and SEQ ID NO:5.
