Nevertheless, the lack of a workable method for consistently tracking plant cells\u2019 mechanical properties severely restricts our comprehension of the mechanical alterations in plant cells under stress. In this study, we used the Double Resonator Piezoelectric Cytometry (DRPC) method to dynamically and non-invasively track changes in the surface stress (\u0394S) generated and viscoelasticity (storage modulus G\u2032 and loss modulus G\u2033) of protoplasts and suspension cells of rice under a drought stress of 5\u201325% PEG6000. The findings demonstrate that rice suspension cells and protoplasts react mechanically differently to 5\u201315% PEG6000 stress, implying distinct resistance mechanisms. However, neither of them can withstand 25% PEG6000 stress; they respond mechanically similarly to 25% PEG6000 stress. The results of DRPC are further corroborated by the morphological alterations of rice cells and protoplasts observed under an optical microscope. To sum up, the DRPC technique functions as a precise cellular mechanical sensor and offers novel research tools for the evaluation of plant cell adversity and differentiating between the mechanical reactions of cells and protoplasts under abiotic stress.<\/jats:p>","DOI":"10.3390\/bios14060303","type":"journal-article","created":{"date-parts":[[2024,6,10]],"date-time":"2024-06-10T08:59:06Z","timestamp":1718009946000},"page":"303","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Comparing the Mechanical Properties of Rice Cells and Protoplasts under PEG6000 Drought Stress Using Double Resonator Piezoelectric Cytometry"],"prefix":"10.3390","volume":"14","author":[{"given":"Yu","family":"Yan","sequence":"first","affiliation":[{"name":"College of Bioscience and Biotechnology, Hunan Agricultural University, Changsha 410128, China"},{"name":"Hunan Provincial Engineering Technology Research Center for Cell Mechanics and Function Analysis, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5128-1429","authenticated-orcid":false,"given":"Tiean","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Bioscience and Biotechnology, Hunan Agricultural University, Changsha 410128, China"},{"name":"Hunan Provincial Engineering Technology Research Center for Cell Mechanics and Function Analysis, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Bioscience and Biotechnology, Hunan Agricultural University, Changsha 410128, China"},{"name":"Hunan Provincial Engineering Technology Research Center for Cell Mechanics and Function Analysis, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhicheng","family":"Kong","sequence":"additional","affiliation":[{"name":"College of Bioscience and Biotechnology, Hunan Agricultural University, Changsha 410128, China"},{"name":"Hunan Provincial Engineering Technology Research Center for Cell Mechanics and Function Analysis, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6071-6586","authenticated-orcid":false,"given":"Weisong","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Bioscience and Biotechnology, Hunan Agricultural University, Changsha 410128, China"},{"name":"Hunan Provincial Engineering Technology Research Center for Cell Mechanics and Function Analysis, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengfang","family":"Tan","sequence":"additional","affiliation":[{"name":"College of Bioscience and Biotechnology, Hunan Agricultural University, Changsha 410128, China"},{"name":"Hunan Provincial Engineering Technology Research Center for Cell Mechanics and Function Analysis, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,9]]},"reference":[{"key":"ref_1","first-page":"525","article-title":"Molecular mechanisms of quenching of reactive oxygen species by proline under stress in plants","volume":"82","author":"Matysik","year":"2002","journal-title":"Curr.
