Dissecting the ROS Signaling Network of Cells

活性氧（ROS）控制着细胞中许多不同的过程，包括细胞死亡、应激反应、衰老和癌症。由于氧化应激的潜在风险是所有需氧生物共同的，阐明植物细胞的ros信号网络将对医学和农业产生重大影响。该项目的长期目标是解剖细胞的ROS信号网络，并确定ROS信号如何在植物细胞中被感知和转导。该计划采用的实验方法将使用遗传，分子，生化和生物信息学研究工具的组合来识别，克隆和表征细胞中参与ROS信号传导的不同基因。研究过程中产生的参与ROS传感的基因鉴定、ROS信号通路和ROS突变体的收集，将为整个科学界提供宝贵的资源。项目所产生的信息将增强对植物生物学的整体认识，并有助于确定活性氧在何种程度上和以何种方式参与不同的生物过程。更广泛的影响。为了提高年轻人对科学的兴趣和理解，将招募高中生和本科生（包括少数民族）参加该项目，并对ROS生物学、分子生物学和生物信息学进行培训。本项目将培训2名研究生、8名本科生和8名高中生。此外，在助学金期间，计划举办四个为期一周的暑期讲习班，每个讲习班25名高中生。拟议的项目将提供跨学科培训，这已成为植物科学成功的必要条件。为了提高高中学生、教师和本科生对ROS代谢的认识，将开发两个针对高中学生和本科生的教学网站，以及一个针对高中教师的在线演示，以分享知识并提高对植物、哺乳动物和其他生物中ROS代谢的认识。

Reactive oxygen species (ROS) control many different processes in cells including cell death, stress responses, aging and cancer. Because the potential risk of oxidative stress is common to all aerobic organisms, elucidating the ROS-signaling network of plant cells would have a significant impact in medicine and agriculture. The long-term goal of the project is to dissect the ROS signaling network of cells and determine how ROS signals are sensed and transduced in plant cells. The experimental approach employed in the program will be to use a combination of genetic, molecular, biochemical and bioinformatic research tools to identify, clone and characterize different genes involved in ROS signaling in cells. The identification of genes involved in ROS sensing, the pathway for ROS signaling, and the collection of ROS-mutants, generated during the course of the proposed research, would serve as a valuable resource for the entire scientific community. The information generated from the project will enhance overall understanding of plant biology, and help determine to what extent and in what manner ROS are involved in different biological process. Broader impacts. To increase interest and understanding of science in young people, high school students and undergraduates, including minorities, will be recruited into the project and trained in ROS biology, molecular biology, and bioinformatics. This project will provide training to 2 graduate students, 8 undergraduates and 8 high school students. In addition, four 1 week summer workshops, 25 high school students each, are planned for the duration of the grant. The proposed project will provide interdisciplinary training that has become imperative for success in plant sciences. To enhance the awareness of high school students, teachers and undergraduates, two teaching-oriented websites targeted to high school students and undergraduates, and an online presentation targeted to high school teachers will be developed to share knowledge and enhance awareness to ROS metabolism in plants, mammals and other organisms.
