Decoding post-translational modification for understanding stress tolerance in plant

Plants undergo deteriorating stress situations, which has an adverse effect on their overall growth, maturation, and development. To mitigate these situations plants undergo regulatory cellular mechanisms including epigenetic changes at both genomic as well as protein levels. Post-transcriptional as well as translational modifications of proteins enhance its dynamics and complexity along with orchestrating several cellular functions in response to external stimuli. One of the most crucial roles of Post Translational Modification is under the stress tolerance mechanisms in plants. PTM creates a fine-tuning between all regulatory networks and serves as a highly responsible phenomenon. Illustrative analysis of post-translational modification in various signaling pathways has generated new insight for designing crop cultivars towards better development with higher yield and increased tolerance. In this review, we have first introduced post-translational modification and their types. Later, we discussed the prevalent biotic-abiotic stress, plants adaptation to the stress response mechanism, and the participation of PTMs in these stress conditions to highlight better agricultural productivity. • PTMs regulate cell programming, signal transduction, and stress response mechanisms. • Plant response to stress is gained through the genomic, transcriptomic, and proteomic approaches. • Various PTMs such as phosphorylation, Ubiquitination, and SUMOylation participate during stress management regulation.
