The results showed that: the explants of strawberry leaves were rather sensitive to kanamycin, and the corresponding concentration of 20 mg/L could substantially inhibit the growth of non-transformed tisse and be used to screen the leaves of strawberry after transformation. Timentin at the concentration of 300 mg/L could be used to eliminate Agrobacterium tumefaciens and had minor impact on the growth of the explants. The preculture time of 2-4 days was beneficial to improve transformation frequency. Co-culture for 2-3 days not only had higher gus transient expression but also avoid the over-growth of agrobacterium. The bacterial concentration of OD(subscript 600nm) 0.4 was the best inoculum density and 10 minutes was the best inoculation time.

结果表明：草毒叶片外植体对卡那霉素较为敏感，适宜的筛选浓度为20mg/L，可明显抑制非转化组织的生长；300mg/L的羧吩青霉素可有效抑菌，对外植体生长影响也较小；预培养2-4d有利于转化；共培养2-3d有利于提高转化频率并避免了农杆菌的过度生长；OD(下标 600nm)值为0.4的菌液侵染10min效果最佳。

Orange-spotted grouper is a benthic protogynous marine fish with sex inversion. It is one of the most important culturing fish in the southeast of Asia. As in other vertebrates, its growth is mainly controlled by growth hormone . Few data are available concerning the regulation of GH in grouper. In this paper, the regulation of growth hormone release from pituitary of orange-spotted grouper and its mRNA level was determined by radioimmunoassay and RNase protection assay.

应用分子克隆技术，构建了斜带石斑鱼生长激素(Growth hormone，GH)基因重组质粒，在大肠杆菌细胞中获得高效表达，亲和层析纯化斜带石斑鱼GH融合蛋白做为抗原，免疫家兔制备特异性抗体，通过酶联免疫实验、放射免疫测定、离体脑垂体静态孵育和液相杂交／核糖核酸酶保护试验及化学发光检测技术，研究了斜带石斑鱼GH分泌及其mRNA表达的调控机制，对于斜带石斑鱼的生长、繁殖、人工养殖等具有重要意义。
