“…MAPK signaling is an ABA-and Ca 2+ -dependent pathway. 8,48,49 In line with previous reports, 50 MAPK1, MAPK3, and MAPK5 decreased and MAPK2 increased in the shoot of this saltsensitive rice. The metabolic pathways, signal transduction, and interactome map of other hormones also are shown in Figures 7-A and 7-B, to visualize the tissue-specific susceptible metabolites and proteins likely effect on rice sensitivity to salt stress.…”

Rice is a staple food crop worldwide; however, salinity stress is estimated to reduce its global production by 50%. Knowledge about initial molecular signaling and proteins associated with sensing salinity among crop plants is limited. We characterized early salt effects on the proteome and metabolome of rice tissues. Omics results were validated by western blotting and multiple reaction monitoring assays and integrated with physiological changes. We identified 8160 proteins and 2045 metabolites in rice tissues. Numerous signaling pathways were induced rapidly or partially by salinity. Combined data showed the most susceptible proteins or metabolites in each pathway that likely affected the sensitivity of rice to salinity, such as PLA1, BON3 (involved in sensing stress), SnRK2, pro-resilin, GDT1, Gproteins, calmodulin activators (Ca 2+ and abscisic acid signaling), MAPK3/5, MAPKK1/3 (MAPK pathway), SOS1, ABC F/D, PIP2-7, and K + transporter-23 (transporters), OPR1, JAR1, COL1, ABA2, and MAPKK3 (phytohormones). Additionally, our results expanded the stress-sensing function of receptor-like kinases, phosphatidylinositols, and Na + sensing proteins (IPUT1). Combined analyses revealed the most sensitive components of signaling pathways causing salt-susceptibility in rice and suggested potential targets for crop improvement.

“…Identified phosphoproteins indicated the role of the phosphorylation of cell-wall metabolism related enzymes in the regulation of the transition from proliferative cell division to cellular differentiation. During de-etiolation of maize seedlings, most phosphoproteins were found to be involved in gene transcription, post-transcriptional regulation, and signal transduction [ 68 ].…”

Food security is a major challenge in the present world due to erratic weather and climatic changes. Environmental stress negatively affects plant growth and development which leads to reduced crop yields. Technological advancements have caused remarkable improvements in crop-breeding programs. Proteins have an indispensable role in developing stress resilience and tolerance in crops. Genomic and biotechnological advancements have made the process of crop improvement more accurate and targeted. Proteomic studies provide the information required for such targeted approaches. The crosstalk among cellular components is being analyzed by subcellular proteomics. Additionally, the functional diversity of proteins is being unraveled by post-translational modifications during abiotic stress. The exploration of precise cellular responses and the networking among different cellular organelles help in the prediction of signaling pathways and protein–protein interactions. High-throughput mass-spectrometry-based protein studies are now possible due to incremental advancements in mass-spectrometry techniques, sample protocols, and bioinformatic tools as well as the increasing availability of plant genome sequence information for multiple species. In this review, the key role of proteomic analysis in identifying the abiotic-stress-responsive mechanisms in various crops was summarized. The development and availability of advanced computational tools were discussed in detail. The highly variable protein responses among different crops have provided a wide avenue for molecular-marker-assisted genetic buildup studies to develop smart, high-yielding, and stress-tolerant varieties to cope with food-security challenges.

The thiol group of cysteine (Cys) residues, often present in the active center of the protein, are of particular importance to protein function which is significantly determined by the redox state of a protein’s environment. Our knowledge of different thiol-based oxidative post-translational modifications (oxiPTMs), which compete for specific protein thiol groups, has increased over the last ten years. The principal oxiPTMs include S-sulfenylation, S-glutathionylation, S-nitrosation, persulfidation, S-cyanylation, and S-acylation. The role of each oxiPTM depends on the redox cellular state, which, in turn, depends on cellular homeostasis under either optimal or stressful conditions. Under these conditions, the metabolism of molecules such as glutathione (GSH), NADPH, nitric oxide (NO), hydrogen sulfide (H2S), and hydrogen peroxide (H2O2) can be altered, exacerbated and, consequently, outside the cell´s control. This review provides a broad overview of these oxiPTMs under physiological and unfavorable conditions, which can regulate the function of target proteins.
