Abstract
Plant cells are in constant communication to coordinate development processes and environmental reactions. Under stressful conditions, such communication allows the plant cells to adjust their activities and development. This is due to intercellular signaling events which involve several components. In plant development, cell-to-cell signaling is ensured by mobile signals hormones, hydrogen peroxide (H2O2), nitric oxide (NO), or hydrogen sulfide (H2S), as well as several transcription factors and small RNAs. Mineral nutrients, including macro and microelements, are determinant factors for plant growth and development and are, currently, recognized as potential signal molecules. This review aims to highlight the role of nutrients, particularly calcium, potassium, magnesium, nitrogen, phosphorus, and iron as signaling components with special attention to the mechanism of response against stress conditions.

PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2019; 142:84-93. [PMID: 31277045 DOI: 10.1016/j.plaphy.2019.06.020] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Revised: 06/13/2019] [Accepted: 06/13/2019] [Indexed: 05/13/2023]
Abstract
S-nitrosylation, regulated by S-nitrosoglutathione reductase (GSNOR), is considered as an important route for nitric oxide (NO)-modulated stress tolerance in plants. However, genetic evidence for the GSNOR-mediated integrated regulation of S-nitrosylation and plant stress response remains elusive until now. In the present study, we used a site-specific nitrosoproteomic approach to identify 334 endogenously S-nitrosylated proteins with 425 S-nitrosylated sites from the wild type (WT) and GSNOR-knockdown (G) tomato plants under both control (C) and sodic alkaline stress (S) conditions. In detail, the results revealed 68, 92, 54 and 56 up-regulated, as well as 10, 36, 14 and 10 down-regulated S-nitrosylated proteins in G-C/WT-C, G-S/WT-S, WT-S/WT-C, and G-S/G-C, which is the first dataset for S-nitrosylated proteins in Solanaceae. These S-nitrosylated proteins are involved in a wide range of various metabolic, cellular and catalytic processes. Based on this data, proteins involving in NO homeostasis control, signaling of Ca2+, ethylene and MAPK, reactive oxygen species (ROS) scavenging, osmotic regulation, as well as energy support pathway have been identified and selected as the key and sensitive targets that were regulated by GSNOR-modulated S-nitrosylation in response to sodic alkaline stress. Taken together, GSNOR is actively involved in the regulation of sodic alkaline stress tolerance by S-nitrosylation. And the present study provided valuable resources and new clues for the study of S-nitrosylation-regulated metabolism in tomato plants.

García MJ, García-Mateo MJ, Lucena C, Romera FJ, Rojas CL, Alcántara E, Pérez-Vicente R. Hypoxia and bicarbonate could limit the expression of iron acquisition genes in Strategy I plants by affecting ethylene synthesis and signaling in different ways. PHYSIOLOGIA PLANTARUM 2014; 150:95-106. [PMID: 23742320 DOI: 10.1111/ppl.12076] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2013] [Accepted: 05/16/2013] [Indexed: 05/20/2023]
Abstract
In a previous work, it was shown that bicarbonate (one of the most important factors causing Fe chlorosis in Strategy I plants) can limit the expression of several genes involved in Fe acquisition. Hypoxia is considered another important factor causing Fe chlorosis, mainly on calcareous soils. However, to date it is not known whether hypoxia aggravates Fe chlorosis by affecting bicarbonate concentration or by specific negative effects on Fe acquisition. Results found in this work show that hypoxia, generated by eliminating the aeration of the nutrient solution, can limit the expression of several Fe acquisition genes in Fe-deficient Arabidopsis, cucumber and pea plants, like the genes for ferric reductases AtFRO2, PsFRO1 and CsFRO1; iron transporters AtIRT1, PsRIT1 and CsIRT1; H(+) -ATPase CsHA1; and transcription factors AtFIT, AtbHLH38, and AtbHLH39. Interestingly, the limitation of the expression of Fe-acquisition genes by hypoxia did not occur in the Arabidopsis ethylene constitutive mutant ctr1, which suggests that the negative effect of hypoxia is related to ethylene, an hormone involved in the upregulation of Fe acquisition genes. As for hypoxia, results obtained by applying bicarbonate to the nutrient solution suggests that ethylene is also involved in its negative effect, since ACC (1-aminocyclopropane-1-carboxylic acid; ethylene precursor) partially reversed the negative effect of bicarbonate on the expression of Fe acquisition genes. Taken together, the results obtained show that hypoxia and bicarbonate could induce Fe chlorosis by limiting the expression of Fe acquisition genes, probably because each factor negatively affects different steps of ethylene synthesis and/or signaling.

Abstract
Protein tyrosine nitration is a post-translational modification (PTM) mediated by reactive nitrogen species (RNS) that is linked to nitro-oxidative damages in plant cells. During the last decade, the identification of proteins undergoing this PTM under adverse environmental conditions has increased. However, there is also a basal endogenous nitration which seems to have a regulatory function. The technological advances in proteome analysis have allowed identifying these modified proteins and have shown that the number and identity of the nitrated proteins change among plant species, analysed organs and growing/culture conditions. In this work, the current knowledge of protein tyrosine nitration in higher plants under different situations is reviewed.

JOURNAL OF PLANT PHYSIOLOGY 2012; 169:1074-83.

Abstract
The effects of benzothiadiazole (BTH) and L-2-oxothiazolidine-4-carboxylic acid (OTC) on the growth and viral content of micropropagated, Plum pox virus (PPV)-infected peach [(Prunus persica (L.) Batsch] 'GF305' plantlets were analyzed. Low BTH and OTC concentrations resulted in a significant increase in the growth of GF305 peach and plum plants, with greater effects in PPV-infected than in healthy GF305 peach plantlets. Neither BTH nor OTC reduced the virus content. In fact, the highest growth and viral contents coincided, especially with the 10 μM BTH treatment. Differing effects on the antioxidative metabolism of PPV-infected GF305 peach plantlets were observed, depending on the compound and the concentration used: BTH decreased GSH, whereas OTC increased it. In PPV-infected plants, the 50 μM OTC treatment produced a decrease in ascorbate peroxidase, catalase, and glutathione peroxidase, but an increase in superoxide dismutase. However, BTH produced a rise in peroxidase activity. Both 10 μM BTH and 50 μM OTC produced H₂O₂ accumulation that was correlated with the histochemical detection of H₂O₂ by 3,3'-diaminobenzidine staining. PPV infection induced NPR1 expression and a synergistic effect occurred in the presence of 50 μM OTC, since this compound produced an up-regulation of NPR1 in both healthy and PPV-infected GF305 peach plantlets. The results showed that GSH, as previously suggested, and/or H₂O₂ could be involved in the regulation of NPR1 expression. Globally, the results show that both OTC and BTH improved the vigor of Prunus species, including peach and plum, under in vitro conditions, producing positive effects on growth, antioxidative metabolism and NPR1 expression. All of these improvements could be critical for more successful ex vitro acclimatization as well as for improved responses to different stresses.
