Expression data from Drosophila subjected to artificial selection on locomotion. Drosophila melanogaster

Genes relevant to manifestion of and variation in locomotor behavior might be differentially expressed in lines selected for divergent levels of locomotion. Keywords: selection group Overall design: Drosophila adults were assessed for locomotor reactivity levels in a behavioral assay that quantified the locomotor response to a mechanical stimulus. A subset of the sampled population was selected as parents for the next generation, with High, Low, and Control selection groups maintained. This artificial selection was continued for 25 generations, with a variety of other behavioral and life history traits assessed for correlation with response to selection for locomotion. At generation 25, male and female flies were collected for RNA extraction and subsequent gene expression analysis.

实验设计概述：以果蝇（Drosophila）成虫为研究对象，通过量化其对机械刺激的运动反应的行为学实验评估其运动反应性水平。从抽样种群中选取部分个体作为下一代亲本，维持高运动组、低运动组与对照组三个选育系。该人工选育过程持续25代，期间同步评估多种其他行为与生活史性状与运动选育响应的相关性。在第25代时，收集雌雄果蝇用于RNA提取及后续基因表达分析。
