Editorial: Regulation of proteolysis and proteome composition in plant response to environmental stress, volume II.

This document is an editorial published in the journal Frontiers in Plant Science. It discusses the regulation of proteolysis and proteome composition in plants in response to environmental stress. The editorial highlights the importance of protein post-translational modifications (PPTMs) in plant stress responses and their role in enhancing proteome diversity. The document includes five papers that cover various aspects of abiotic and biotic stress and focus on PPTMs such as phosphorylation, lysine 2-hydroxyisobutyrylation, and succinylation. The research presented in the papers explores the impact of these modifications on plant defense mechanisms and metabolic pathways. Overall, the editorial emphasizes the need for further research in the area of PPTMs in plant biology. [Extracted from the article]
