The estrogen-inducible egg yolk precursor, vitellogenin, of the European sea bass (Dicentrarchus labrax) has received considerable scientific attention by virtue of its central importance in determination of oocyte growth and egg quality in this important aquaculture species. However, the multiplicity of vitellogenins in the sea bass has only recently been examined. Recent cloning and homology analyses have revealed that the sea bass possesses the three forms of vitellogenin, VtgAa, VtgAb and VtgC, reported to occur in some other highly evolved teleosts. Progress has been made in assessing the relative abundance and special structural features of the three Vtgs and their likely roles in oocyte maturation and embryonic nutrition. This report discusses these findings in the context of our prior knowledge of vitellogenesis in this species and of the latest advances in our understanding of the evolution and function of multiple Vtgs in acanthomorph fishes.
欧洲海鲈（Dicentrarchus labrax）的雌激素诱导性卵黄前体——卵黄蛋白原，因其在这一重要水产养殖物种的卵母细胞生长和卵质量测定中具有核心重要性而受到了相当多的科学关注。然而，海鲈中卵黄蛋白原的多样性直到最近才得到研究。最近的克隆和同源性分析表明，海鲈拥有三种卵黄蛋白原形式，即VtgAa、VtgAb和VtgC，据报道在其他一些高度进化的硬骨鱼中也存在。在评估这三种卵黄蛋白原的相对丰度、特殊结构特征及其在卵母细胞成熟和胚胎营养中的可能作用方面已经取得了进展。本报告结合我们对该物种卵黄发生的先前认识以及我们对棘鳍鱼类中多种卵黄蛋白原的进化和功能理解的最新进展，讨论了这些发现。
