About this Research Topic
Plants are frequently faced with abiotic stress such as low nutrient availability, drought, flood, salinity, extreme temperatures, and high UV. The effectiveness of plants adaptive responses to stress depends on an intricate coordination of multiple signaling pathways, in which protein post-translational modifications (PTMs) are involved. PTMs may control protein activity, localization, stability, and protein-protein interactions in a variety of cellular processes to mitigate the potential damage of environmental stress.
PTMs expand proteome diversity, enlarge its functionality, and allow for dynamic responses in short time periods, all at relatively low costs for the cell. Therefore, plant signaling pathways largely rely on modifications of specific amino acid residues in proteins that induces rapid changes to achieve a response specific to the type of stress and its duration. Although the catalogue of PTMs of plant proteome is quickly expanding, their impact on the protein and function often remains obscure.
The Research Topic will provide an overview of recent studies on various PTMs, with a special emphasis on the processes involved in abiotic stress signaling and response. Accordingly, we aim to collect Original Research Articles, Methods, Reviews, Mini-reviews. Perspectives, and Opinions that focus on but are not limited to the following themes:
• Phospohorylation
• Glycosylation
• Acetylation
• Ubiquitylation
• S-Nitrosylation and nitration
• Persulfidation
• Sulfenylation
• Glutathionylation
• SUMOyation
• Methylation
• Carbonylation
• Lipidation (N-Myristoylation, S-Palmitoylation, Prenylation)
An additional aim is to present global views on this topic and to encourage women, minority, and early-career researchers to contribute to this Research Topic.
