“…Significantly, higher activities of SOD and POD were presented by Zou et al [34] with NaCl treatment of 100 mM for 10d, but they showed insignificant increase of CAT and APX activities, and significant decrease of GR and DHAR activities under same treatment. The activities of SOD and POD were increased with increasing the levels of salt concentrations in T. monococcum seedlings [39].…”

Wheat Improvement, Management and Utilization

Wheat is consumed as a staple food by more than 36% of world population. Wheat provides nearly 55% of the carbohydrates and 20% of the food calories consumed globally. The productivity of wheat is often adversely affected by salt stress which is associated with decreased germination percentage, reduced growth, altered reproductive behavior, altered enzymatic activity, disrupted photosynthesis, damage of ultrastructure of cellular components, hormonal imbalance, and oxidative stress. Different approaches have been adopted to improve plant performance under salt stress: introduction of genes, screening of better performing genotypes, and crop improvement through conventional breeding methods which are often not so successful and suitable due to time-consuming or reduction of plant vigor with the succession of time. Uses of exogenous phytoprotectants, seed priming, nutrient management, and application of plant hormone are convenient for improving plant performances. This chapter reviews the mechanism of damage of wheat plants under salt stress and also the recent approaches to improve growth and productivity of salt-affected wheat plants emphasizing the use of exogenous phytoprotectants from the available literature.

“…Proteomics have been used as a useful tool for facilitating the comparison of complex mixtures of proteins, and it is now widely applied for exploring the molecular mechanisms of plants in response to environmental stresses (Lv et al, ). Recently, proteomics‐based technologies have been broadly employed to identify the proteins responsible for salinity tolerance in halophytes such as Suaeda corniculata (Pang, Zhang, Zang, Wei, & Yan, ), Halogeton glomeratus (Wang, Yao, Li, Meng, & Ma, ), and Tangut nitraria (Cheng et al, ), which has accelerated the understanding of the protein‐level molecular mechanisms of plant salt tolerance.…”

Isobaric tags for relative and absolute quantification‐based proteomic analysis of Puccinellia tenuiflora inoculated with arbuscular mycorrhizal fungi reveal stress response mechanisms in alkali‐degraded soil

Alkali soil is a major abiotic constraint that limits plant distribution and yield in the northeast of China. Puccinellia tenuiflora is considered the most promising grass species for salt‐alkali grassland restoration. However, there is little information on the molecular mechanisms underlying how arbuscular mycorrhizal fungi (AMF) enhances P. tenuiflora stress responses in alkali‐degraded soil. In this study, AMF colonization, growth, photosynthetic pigments, and inorganic ion contents were measured. Isobaric tags for relative and absolute quantification‐based quantitative proteomic technology were employed to identify the differentially abundant proteins in P. tenuiflora seedlings with or without AMF under alkalinity stress. The results showed that AMF colonization increased seedling biomass, photosynthetic pigment contents, and K+/Na+ ratio under alkalinity stress. Moreover, a total of 598 proteins were significantly differentially regulated in P. tenuiflora seedlings after AMF inoculation under alkalinity stress compared with under alkalinity stress alone. The results showed that AMF inoculation significantly improved protein synthesis, reactive oxygen species scavenging, and nitrogen metabolism to promote the biosynthesis of osmotic substances in response to alkalinity stress. In addition, P. tenuiflora seedlings produced more energy to compensate for the energy loss caused by alkalinity stress after AMF inoculation. In conclusion, these findings provide new insights into the physiological mechanisms of the response to alkali‐degraded soil in P. tenuiflora seedlings with AMF and also clarify the role of AMF in the molecular regulation network of P. tenuiflora under alkalinity stress.

“…Phosphorylation is mostly found in hydroxylated amino acids such as serine (S), threonine (T) and Y residues. Studies of target proteins of S/T and Y phosphorylation in crop plants include wheat, maize, and sugar beet under salt stress [45,46,47] and wheat and several beans under drought stress [48,49]. These environmental stresses mediated by protein phosphorylation can influence crop productivity by retarded growth or imparted fertility.…”

The efficiency of stress-induced adaptive responses of plants depends on intricate coordination of multiple signal transduction pathways that act coordinately or, in some cases, antagonistically. Protein post-translational modifications (PTMs) can regulate protein activity and localization as well as protein–protein interactions in numerous cellular processes, thus leading to elaborate regulation of plant responses to various external stimuli. Understanding responses of crop plants under field conditions is crucial to design novel stress-tolerant cultivars that maintain robust homeostasis even under extreme conditions. In this review, proteomic studies of PTMs in crops are summarized. Although the research on the roles of crop PTMs in regulating stress response mechanisms is still in its early stage, several novel insights have been retrieved so far. This review covers techniques for detection of PTMs in plants, representative PTMs in plants under abiotic stress, and how PTMs control functions of representative proteins. In addition, because PTMs under abiotic stresses are well described in soybeans under submergence, recent findings in PTMs of soybean proteins under flooding stress are introduced. This review provides information on advances in PTM study in relation to plant adaptations to abiotic stresses, underlining the importance of PTM study to ensure adequate agricultural production in the future.
