Changing climate conditions promote pest and pathogen development globally. Additionally, plants must deal with various abiotic stresses amplified by more and more intense industrial pressure. Plants are capable of inducing defense responses against environmental stresses. Among these responses, the regulation of proteolysis and hence the quality and composition of proteins are of fundamental importance. Proteolysis is an essential process required for protein metabolism that employs different types of proteolytic enzymes, for instance, serine, aspartic, metallo- and cysteine peptidases. As unregulated proteolysis could be a serious threat to cells, plants are equipped with a battery of direct and endogenous peptidase inhibitors. Thus, a continuous better understanding of the mechanisms underlying the precise regulation of proteolytic activity and the dynamic changes in the proteome of plants affected by environmental stresses should still be a matter of concern for the international forum of plant stress biologists.
This Research Topic aims to collect and discuss the most recent advances on protein metabolism mechanisms during plant environmental stresses responses using molecular, biochemical, physiological, structural, and systems biology approaches in plants including crop and wild species.
We expect submissions of original research, reviews, and methods, including (but not limited to) investigations on the following subtopics:
1. Novel players involved in the proteolytic-antiproteolytic balance.
2. Synthesis, degradation, and recycling of amino acids and proteins.
3. Roles of proteolytic enzymes and their activators and inhibitors.
4. Protein composition and quality systems: control and regulation.
5. Protein functional status, appropriate folding, post-translational modifications.
6. Hormonal regulation and signal transduction of amino acids and proteins metabolism.
7. Crosstalk between amino acid and protein metabolism and energy, carbohydrate and secondary metabolism, and the carbon-nitrogen budget.
8. Profiling of proteome and post-translationally modified proteome
Please note that a broad spectrum of submissions on protein and amino acid metabolism, profiling of proteome, and post-translationally modified proteome are welcomed, but descriptive manuscripts lacking significant mechanistic and/or physiological insights would be rejected without peer review.
