[PMID: 38459275 DOI: 10.1007/s11103-024-01432-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Accepted: 02/21/2024] [Indexed: 03/10/2024]
Abstract
Nano-interactions are well known for their positive as well as negative impacts on the morphological and physiological systems of plants. Keeping in mind, the conformational changes in plant proteins as one of the key mechanisms for stress adaptation responses, the current project was designed to explore the effect of glutathione-capped and uncapped zinc nano-entities on Catharanthus roseus shoot cultures. Zinc nanotreatment (0.05 μg/mL) significantly induced ester production in C. roseus shoots as detected by Gas Chromatography-Mass spectrometry. These nanotreated shoots were further subjected to peptide-centric nano-LC-MS/MS analysis. Mass spectrometry followed by a Heat map revealed a significant effect of zinc nanoparticles on 59 distinct classes of proteins as compared to control. Proteins involved in regulating stress scavenging, transport, and secondary metabolite biosynthesis were robustly altered under capped zinc nanotreatment. UniProt database identified majority of the localization of the abundantly altered protein in cell membranes and chloroplasts. STRING and Cytoscape analysis assessed inter and intra coordination of triosephosphate isomerase with other identified proteins and highlighted its role in the regulation of protein abundance under applied stress. This study highlights the understanding of complex underlying mechanisms and regulatory networks involved in proteomic alterations and interactions within the plant system to cope with the nano-effect.

Phase variation of manganese oxide in the MnO@ZnO nanocomposite with calcination temperature and its effect on structural and biological activities. Sci Rep 2023; 13:21542. [PMID: 38057479 PMCID: PMC10700637 DOI: 10.1038/s41598-023-48695-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Accepted: 11/29/2023] [Indexed: 12/08/2023] Open
Abstract
Having powerful antibacterial and antioxidant effects, zinc oxide and manganese oxide nanomaterials are of great interest. Here we have synthesized manganese oxide decorated zinc oxide (MZO) nanocomposites by co-precipitation method, calcined at different temperatures (300-750 °C) and studied various properties. Here the crystalline structure of the nanocomposite and phase change of the manganese oxide are observed with calcination temperature. The average crystalline size increases and the dislocation density and microstrain decrease with the increase in calcined temperature for the same structural features. The formation of composites was confirmed by XRD pattern and SEM images. EDAX spectra proved the high purity of the composites. Here, different biological properties change with the calcination temperature for different shapes, sizes and structures of the nanocomposite. Nanomaterial calcined at 750 °C provides the best anti-microbial activity against Escherichia coli, Salmonella typhimurium, Shigella flexneri (gram-negative), Bacillus subtilis and Bacillus megaterium (gram-positive) bacterial strain at 300 µg/mL concentration. The nanomaterial with calcination temperatures of 300 °C and 450 °C provided better antioxidant properties.
