“…The ability to measure a variety of PTMs is a unique aspect of advanced proteomics technologies. Currently, more than 200 biological relevant PTMs have been reported [47] and several types of them, such as phosphorylation, acetylation, glycosylation, and thiol-based redox modifications, have been studied extensively [24,32,48–50]. …”

The widespread use of engineered nanomaterials or nanotechnology makes the characterization of biological responses to nanomaterials an important area of research. The application of omics approaches, such as mass spectrometry-based proteomics, has revealed new insights into the cellular responses of exposure to nanomaterials, including how nanomaterials interact and alter cellular pathways. In addition, exposure to engineered nanomaterials often leads to the generation of reactive oxygen species and cellular oxidative stress, which implicates a redox-dependent regulation of cellular responses under such conditions. In this review, we discuss quantitative proteomics-based approaches, with an emphasis on redox proteomics, as a tool for system-level characterization of the biological responses induced by engineered nanomaterials.

“…MPK4 is activated by upstream kinases in response to developmental cues, pathogen invasion or other environmental changes, and then interacts with and phosphorylates downstream substrates. 32 AtMKK2 and AtMEK1 (AtMKK1) are two MAP kinase kinases (MAPKKs), which share 65% sequence identity. 33 In a yeast two-hybrid (Y2H) assay, AtMEK1 and AtMKK2 specifically interacted with AtMPK4.…”

Mitogen-activated protein kinase (MPK) cascades play important roles in plant development, immune signaling and stress responses. MPK4 was initially identified as a negative regulator in systemic acquired resistance (SAR) because the levels of salicylic acid (SA) and reactive oxygen species (ROS) were higher in the Arabidopsis mpk4 mutant. MPK4 is highly expressed in guard cells, specialized epidermal cells forming stomatal pores on leaf surface that function at the frontline of bacterial pathogen invasion. In addition to biotic stresses, stomatal guard cells also mediate cellular responses to abiotic stimuli such as drought and CO changes. MPK4 appears to play different roles in different plant systems. In this review, we briefly discuss the protein kinase MPK4 functions and focus on its signaling roles in different plant systems, especially in stomatal guard cells.

“…Protein phosphorylation is the most studied PTMS and its elucidation is a central goal of functional proteomics research in plant biology. Many studies have been reported about their role in abiotic‐stress, energy metabolism, hormone regulation, etc. However, the analysis of phosphoproteins on a proteome‐wide scale has been less well studied in relation to anther development (Table ).…”

In flowering plants, anther development plays crucial role in sexual reproduction. Within the anther, microspore mother cells meiosis produces microspores, which further develop into pollen grains that play decisive role in plant reproduction. Previous studies on anther biology mainly focused on single gene functions relying on genetic and molecular methods. Recently, anther development has been expanded from multiple OMICS approaches like transcriptomics, proteomics/phosphoproteomics, and metabolomics. The development of proteomics techniques allowing increased proteome coverage and quantitative measurements of proteins which can characterize proteomes and their modulation during normal development, biotic and abiotic stresses in anther development. In this review, we summarize the achievements of proteomics and phosphoproteomics with anther and pollen organs from model plant and crop species (i.e. Arabidopsis, rice, tobacco). The increased proteomic information facilitated translation of information from the models to crops and thus aid in agricultural improvement.
