Molecular mechanisms of caste differentiation and division of labor in social aphids

为了了解社会性蚜虫阶层分化、社会行为、劳动分工的分子基础，通过cDNA减法实验和2D-PAGE分析，获得了许多在军人和非军人中特异性或显性表达的基因和蛋白。此外，本研究还分析了一种新型蛋白质的生物学功能，这种蛋白质参与了一种社会行为——胆囊修复。

To understand the molecular bases of caste differentiation, social behavior, division of labors in social aphids, many genes and proteins that expressed specifically or dominantly in soldiers were obtained from a cDNA subtraction experiment and 2D-PAGE analysis between soldiers and non-soldiers. Also, biological function of a novel protein that is involved in a social behavior, gall repair, was analyzed in this study.
