Abstract:
In many signaling pathways, various factors have been isolated by molecular genetic studies and wholegenome analysis. Understanding the interactions among these factors is crucial to understanding the signaling process as a whole. Recent studies on auxin signaling in the regulation of plant growth and development have discovered primary factors interacting with each other, and elucidated a very simple pathway modulating gene expression in response to auxin. However, these studies of auxin-signaling led to the question of how such a simple pathway generates multiple types of regulation in various processes of different cells throughout the life of a plant. Here, we provide an overview of recent progress in auxin biology focusing on protein-protein interactions in the signal transduction pathway and discuss various possibilities and approaches to resolve the issue.
