Abstract Have you ever planted a seed? Did you plant it right side up? Of course you never had to think about it; there is no right-side-up. Germinating seedlings know which way is up, because of gravity. Gravity is a fundamental stimulus directing plant growth and development. Yet, even so, we still don’t fully understand how plants respond to it. One of the biggest questions remaining is that of signal transduction, how plants convert the physical information provided by gravity into a biochemical response.

All Rights Reserved. 2 This dissertation titled Gravitropic Signal Transduction: A Systems Approach to Gene Discovery by KAIYU SHEN has been approved for the Program of Molecular and Cellular Biology and the College of Arts and Sciences by Sarah E. Wyatt Professor of Environmental and Plant Biology Robert Frank Dean, College of Arts and Science 3 ABSTRACT SHEN, KAIYU, Ph.D., May 2013, Molecular and Cellular Biology Gravitropic Signal Transduction: A Systems Approach to Gene Discovery Director of Dissertation: Sarah E. Wyatt Gravity is an important stimulus for plants. Gravitropism, the plants’ response to gravity, can be divided into three phases: gravity perception, signal transduction and response. Various theories have been proposed to explain the process of gravitropism, yet more genes are needed to elucidate the mechanism of gravitropic signal transduction. A transcriptome analysis, in combination with the Gravity Persistent Signal treatment, was performed to specifically study the genes involved in signal transduction. Analysis generated a list of 318 transcripts that were differentially expressed in plants that were reoriented with respect to gravity as compared to vertical controls. Based on the expression profiles and gene function annotations, five transcription factors, WRKY18, WRKY26, WRKY33, BT2 and ATAIB, were selected for further study. In addition to the standard analysis of differentially expressed genes, a systems approach was adopted to uncover more gravity related genes.

It is published by the American Society for Gravitational and Space Biology, a non-profit organization whose members share a common goal of furthering the understanding of the biological effects of gravity and the use of the unique environment of spaceflight for biological research. Gravitational and Space Biology is overseen by a steering committee consisting of the Publications Committee, the Editor, the President, and the Secretary-Treasurer of the ASGSB. The American Society for Gravitational and Space Biology was created in 1984 to provide an avenue for scientists interested in gravitational and space biology to share information and join together to speak with a united voice in support of this field of science.
