Lie group analysis of the photo-induced fluorescence of Drosophila oogenesis with the asymmetrically localized Gurken protein has been performed systematically to assess the roles of ligand-receptor complexes in follicle cells. The (2×2) matrix representations resulting from the polarized tissue spectra were employed to characterize the asymmetrical Gurken distributions. It was found that the fluorescence of the wild-type egg shows the Lie point symmetry X 23 at early stages of oogenesis. However, due to the morphogen regulation by intracellular proteins and extracellular proteins, the fluorescence of the embryogenesis with asymmetrically localized Gurken expansions exhibits specific symmetry features: Lie point symmetry Z 1 and Lie point symmetry X 1. The novel approach developed herein was successfully used to validate that the invariant-theoretical characterizations are consonant with the observed asymmetric fluctuations during early embryological development.
利用不对称定位的果蝇胚盘生成蛋白对果蝇卵子发生过程中的光诱导荧光进行了李群分析，以系统评估配体 - 受体复合物在卵泡细胞中的作用。由偏振组织光谱产生的(2×2)矩阵表示被用于表征不对称的果蝇胚盘生成蛋白分布。研究发现，野生型卵子的荧光在卵子发生早期呈现李点对称性X 23。然而，由于细胞内蛋白和细胞外蛋白的形态发生素调控，具有不对称定位的果蝇胚盘生成蛋白扩展的胚胎发生荧光表现出特定的对称特征：李点对称性Z 1和李点对称性X 1。本文开发的新方法成功用于验证不变理论表征与早期胚胎发育过程中观察到的不对称波动是一致的。
