Tropisms Neal, Carolyn O.S. [1], Yang, Peizhen [2], Masson, Patrick H. [3], Craig, Elizabeth A. [2]. Exploring the early events of root gravity and touch signal transduction with a proteomics approach. Our lab conducted a proteomic analysis of Arabidopsis root tips to identify proteins whose abundance and/or modification change early in response to mechano-stimulation. The study identified proteins with interesting temporal patterns of response to gravity and touch stimulation, and uncovered groups of differentially regulated proteins with clearly related functions that had not previously been implicated in gravity or touch signaling. We are using a combination of reverse genetics, temporal and spatial expression analysis in Arabidopsis, and transformation-rescue experiments in Saccharomyces cerevisiae, to identify and characterize the potential role of one of these proteins, which we call SKU15, in mechano-transduction.
