Nitric Oxide Signalling in Arabidopsis thaliana : Redox Modification in Mitochondria and Regulation of Transcription
Year: 2009
Type: dissertation
Abstract: The role of nitric oxide (NO) in several signalling routes and in response to different stimuli has been investigated and recognised as fundamental in plants. Despite the proved importance of NO, little is known about signalling pathways downstream of it. Given the ability of NO to react with a range of target molecules, it is likely that there are several cellular 'NO sensor' able to act as signal transducers. The present work focuses on two aspect of the NO plant interaction with the intention of better understanding the signalling cascade downstream this molecule. Studying the relation between NO and mitochondria via analysing the S-nitrosylated protein pool, an important role for the glycine decarboxylase complex during plant-stress responses was discovered. Moreover, using a bioinformatic approach it was possible to analyze the relation between NO and plant transcriptome from a different and not conventional point of view. Such analyses of common TFBS and promoter modules in NO regulated genes may be a fist step to provide the basis to understand regulatory networks involved in gene expression profiles
