Post-translational modifications: emerging regulators manipulating jasmonate biosynthesis and signaling

Jasmonate (JA) is one of the key phytohormones essential for plant development and defense processes. The core JA biosynthetic and signaling pathways have been well-characterized. Notably, post-translational modifications (PTMs), which affect the protein structures and functions, have emerged as critical mechanisms to modulate JA output at different spatiotemporal levels. Disruption of PTMs in JA biosynthesis and signaling would cause the dysfunction of vital biological processes. Here, we give an overview of the PTMs that have been identified in JA biosynthetic and signaling pathways, and provide insights into the mechanisms by which PTMs define JA responses.
