GOLVEN signaling peptides regulate multiple developmental processes in plants

Ana Fernandez Salina UGent (2012)
abstract
Multicellular organisms require highly coordinated cell growth and differentiation. This level of complexity is achieved through regulated communication between different cells. In vertebrates, peptide hormones and neurotransmitters have been well studied for many years. In contrast, research on cell-to-cell communication in plants has focused mainly on classical phytohormones. In 1991, the discovery of the first peptide hormone in tomato opened a new field of investigation in plant cell signaling. Since then, new peptides have been identified and associated to diverse developmental processes, confirming that the role of these messengers had been previously overlooked. The Arabidopsis thaliana genome contains thousands of small open reading frames potentially coding for peptide hormones and it is expected that many more signaling peptide families remain to be identified and characterized. Because increasing evidence suggests their involvement in different developmental programs, it will be important to study the interaction of peptide signaling with other hormonal pathways. The aim of this work was to contribute to the characterization of a novel family of signaling peptides and its function within the plant. The GOLVEN (abbreviated as GLV) peptide family was identified in an in silico search for new peptide hormones. In this study, we conducted the comprehensive functional analysis of this family composed of 11 members in Arabidopsis. For that purpose, we combined the study of expression patterns and the analysis of mutant phenotypes. We then focused on specific processes controlled by the GLV signaling pathway and analyzed the crosstalk between GLV peptides and the phytohormone auxin.
