Crosstalk Between Different Post-translational Modifications and Its Regulatory Mechanisms in Plant Growth and Development
Post-translational modifications(PTMs)have key regulatory roles in cell signal transduction networks.In addition to be a single PTM,many proteins undergo the regulation of multiple different types of PTMs,which functions in an orchestrated manner to adapt external or internal environmental cues.Such PTM crosstalk affects protein interactions,stabilities and subcellular localizations,and ultimately acts as a signaling hub to control diverse biological processes.Although PTM crosstalk has been extensively studied in humans and animals,the investigation in plants is just emerging.In this review,we discuss recent advances in crosstalk among three of the most common PTMs in plants,including phosphorylation,ubiquitination,and sumoylation,furthermore we highlight how this crosstalk may be connected to downstream signaling outputs.
