ABSTRACT:
BACKGROUND OF THE INVENTION
Farmed fish, such as ayu or grouper, are commercially valuable crops. A means of increasing the growth rate or size of fish crops is therefore commercially useful.
SUMMARY OF THE INVENTION
The invention is based on the discovery of three new fish growth hormone genes (from Plecoglossus altivelis, Epinephelus awoara, and Danio rerio) that can be used to increase fish crop production. For example, each of the new fish growth hormone genes can be used to generate transgenic fish expressing a fish growth hormone of the invention. These fish will exhibit greater growth rates and body sizes than the parent fish from which the transgenic fish was derived. Alternatively, the growth hormones can be recombinantly produced and introduced into the fish diet (see, e.g., Ben-Atia et al., Gen. Compar. Endocrinol. 113:155-164, 1999).
In addition, the growth hormone polypeptides and fragments thereof can be used to generate antibodies that specifically bind to a growth hormone of the invention. These antibodies can be used to, e.g., detect fish pituitary tissue in a sample. Other fragments, such as the signal sequence, can be fused to heterologous proteins to render them secretable. The growth hormone cDNA and fragments thereof can be used to screen DNA libraries (e.g., genomic or cDNA libraries) to isolate other related genes and the growth hormones which they encode.
The sequences of the new fish growth hormones are given below:
