Abstract
Cold and drought stress considerably suppress the development of plants. In this study, a new MYB (v-myb avian myeloblastosis viral)TF gene, MbMYBC1, was isolated from the M. baccata and located in nucleus. MbMYBC1 has a positive response to low temperature and drought stress. After being introduced into Arabidopsis thaliana, the physiological indicators of transgenic Arabidopsis had corresponding changes under these two stresses, the activities of catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) increased, electrolyte leakage rate (EL) and the content of proline increased, but the content of chlorophyll decreased. In addition, its overexpression can also activate the downstream expression of AtDREB1A, AtCOR15a, AtERD10B and AtCOR47 related to cold stress and AtSnRK2.4, AtRD29A, AtSOD1and AtP5CS1 related to drought stress. Based on these results, we speculate that MbMYBC1 can respond to cold and hydropenia signals, and can be used in transgenic technology to improve plant tolerance to low temperature and drought stress.

Guo J, Li S, Brestic M, Li N, Zhang P, Liu L, Li X. Modulations in protein phosphorylation explain the physiological responses of barley (Hordeum vulgare) to nanoplastics and ZnO nanoparticles. JOURNAL OF HAZARDOUS MATERIALS 2023; 443:130196. [PMID: 36272376 DOI: 10.1016/j.jhazmat.2022.130196] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 10/12/2022] [Accepted: 10/12/2022] [Indexed: 06/16/2023]
Abstract
To address the knowledge gap on the effects of the co-existence of nanomaterials on plant growth, barley (Hordeum vulgare L.) plants were irrigated with zinc oxide nanoparticles (0.5 g L-1), nanoplastics (1 g L-1), and the combination of these two nanomaterials for 10 days. The co-existence of nanoplastics and ZnO nanoparticles increased H2O2 concentration by 12.76% and 38.30%, compared with the ZnO nanoparticles and nanoplastics exposure. The concentration of abscisic acid (ABA) in plants under the co-existence of nanoplastics and ZnO nanoparticles was 29.53% and 10.42% higher than that in ZnO nanoparticles treated plants and nanoplastics treated plants. The global analysis of phosphoproteomics identified 132 phosphorylated proteins and 173 phosphorylation sites in barley leaves exposed to the nanomaterial combination, which were related to photosynthesis, carbon fixation, nitrogen metabolism, and arginine and proline metabolisms. Further physiological analysis indicated that the combination of ZnO nanoparticles and nanoplastics caused larger damage to the systems of antioxidant and carbohydrate metabolisms as exemplified by decreased activities of apoplastic peroxidases (25.10%-48.60%), glutathione reductase (91.07%-94.94%), and sucrose synthase (53.59%-61.19%) in roots and increased cell wall invertase activity (12.97%-17.61%) in leaves, compared with the single nanomaterial treatments. These results indicate that the modulations in protein phosphorylation were closely related to the physiological responses to nanomaterial exposure, suggesting that the co-existence of nanomaterials may lead to greater impacts than single ones.

[PMID: 30678100 PMCID: PMC6406717 DOI: 10.3390/biom9020039] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 01/12/2019] [Accepted: 01/14/2019] [Indexed: 12/11/2022] Open
Abstract
Tobacco mosaic virus (TMV) is a common source of biological stress that significantly affects plant growth and development. It is also useful as a model in studies designed to clarify the mechanisms involved in plant viral disease. Plant responses to abiotic stress were recently reported to be regulated by complex mechanisms at the post-translational modification (PTM) level. Protein phosphorylation is one of the most widespread and major PTMs in organisms. Using immobilized metal ion affinity chromatography (IMAC) enrichment, high-pH C18 chromatography fraction, and high-accuracy mass spectrometry (MS), a set of proteins and phosphopeptides in both TMV-infected tobacco and control tobacco were identified. A total of 4905 proteins and 3998 phosphopeptides with 3063 phosphorylation sites were identified. These 3998 phosphopeptides were assigned to 1311 phosphoproteins, as some proteins carried multiple phosphorylation sites. Among them, 530 proteins and 337 phosphopeptides corresponding to 277 phosphoproteins differed between the two groups. There were 43 upregulated phosphoproteins, including phosphoglycerate kinase, pyruvate phosphate dikinase, protein phosphatase 2C, and serine/threonine protein kinase. To the best of our knowledge, this is the first phosphoproteomic analysis of leaves from a tobacco cultivar, K326. The results of this study advance our understanding of tobacco development and TMV action at the protein phosphorylation level.
