项目摘要

PROJECT SUMMARY The roundworm C. elegans is one of the most widely studied and powerful genetic model organisms in biology. Many experiments in C. elegans genetics require time-consuming and low throughput manual procedures. For example, the forward genetic screen, through which genes influencing a phenotype are found by identification of mutants, often involves assessment of tens of thousands of individual animals. Full exploitation of C. elegans as a model system will benefit tremendously from automation. We will develop automated methods for performing genetic screens and many other tasks routinely done in C. elegans labs. The key components of the system will be a moving-camera machine vision system for monitoring individual worms on various substrates, and a robotic arm capable of transferring individual worms from one plate to another. To test and refine our methods, we will apply our automation system to perform a saturation genetic screen for modifiers of developmentally-timed sleep, which has molecular and behavioral similarities to sleep in mammals.

项目概要线虫是世界上研究最广泛、最强大的遗传模型生物之一。生物学。线虫遗传学的许多实验需要耗时且低通量的手动操作程序。例如，正向遗传筛选，通过它发现影响表型的基因通过识别突变体，通常需要对数以万计的个体动物进行评估。满的利用线虫作为模型系统将极大地受益于自动化。我们将开发用于执行遗传筛选和线虫实验室中常规完成的许多其他任务的自动化方法。该系统的关键组件将是一个移动摄像机机器视觉系统，用于监控个人各种基质上的蠕虫，以及能够将单个蠕虫从一个盘子转移到一个机器人手臂其他。为了测试和完善我们的方法，我们将应用我们的自动化系统来执行饱和遗传筛选发育定时睡眠的修饰因子，其与睡眠在分子和行为上相似哺乳动物。
