项目摘要

Organisms can alter their physical form by varying the genes that they activate. However, the evolutionary forces that shape genes activated in different forms remain unclear. The objective of this research program is to gain a greater understanding of how natural selection affects genes that are differentially activated between forms. Goodisman and Yi will use social insects as models for investigating this question. They will use molecular genetic techniques to detect genes differentially activated between different social insect castes and sexes. They will then use evolutionary analyses to (1) test the effect of caste-specific gene activation on molecular evolution and (2) test the effect of differing mating system on the evolution of sex-specific genes. This research is of broad scientific importance because it advances our understanding of the evolution of genes that lead to the development of different organismal forms. Goodisman and Yi will uncover how genes that are expressed under distinct environmental conditions evolve. Their studies will also add to our knowledge of the evolution of sex differences. Finally, this research increases our understanding of the molecular basis underlying the success of social insects, which are among the most ecologically successful and economically important of animal species.

生物体可以通过改变它们激活的基因来改变它们的物理形态。然而，形成以不同形式激活的基因的进化力量仍不清楚。这个研究项目的目的是为了更好地理解自然选择是如何影响不同形式的不同激活基因的。Goodisman和Yi将使用群居昆虫作为模型来研究这个问题。他们将使用分子遗传学技术来检测不同社会性昆虫种姓和性别之间激活的基因差异。然后，他们将使用进化分析来(1)测试种姓特异性基因激活对分子进化的影响；(2)测试不同的交配制度对性别特异性基因进化的影响。这项研究具有广泛的科学重要性，因为它促进了我们对导致不同生物形式发展的基因进化的理解。Goodisman和Yi将揭示在不同环境条件下表达的基因是如何进化的。他们的研究也将增加我们对性别差异进化的认识。最后，这项研究增加了我们对社会性昆虫成功的分子基础的理解，这些昆虫是生态上最成功和经济上最重要的动物物种之一。
