While it is commonly assumed that biofilm-dwelling cells are glued together by the matrix, how the cell-matrix interaction depends on the specific biochemistry of the matrix components and how this interaction varies during biofilm growth remains unclear.

Downregulation of VPS and surface trimming by the polysaccharide lyase RbmB cause surface remodeling as biofilms age, shifting the nature of cell-matrix interactions from attractive to repulsive and facilitating cell dispersal as aggregated groups. Our results suggest a new conceptual model in understanding the intricate cell-matrix interaction as the major driver for biofilm development, which is potentially generalizable to certain other biofilm-forming species and exopolysaccharides.\n                <\/jats:p>","DOI":"10.1101\/2024.11.11.623042","type":"posted-content","created":{"date-parts":[[2024,11,12]],"date-time":"2024-11-12T23:30:29Z","timestamp":1731454229000},"source":"Crossref","is-referenced-by-count":0,"title":["Surface remodeling and inversion of cell-matrix interactions underlies community recognition and dispersal in\n                  <i>Vibrio cholerae<\/i>\n                  biofilms"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0559-6179","authenticated-orcid":false,"given":"Alexis","family":"Moreau","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danh T.","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex","family":"Hinbest","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony","family":"Zamora","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ranjuna","family":"Weerasekera","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katherine","family":"Matej","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuening","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Sanchez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ignacio Rodriguez","family":"Brenes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung-Shen Benny","family":"Tai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1751-4895","authenticated-orcid":false,"given":"Carey D.","family":"Nadell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8966-6604","authenticated-orcid":false,"given":"Wai-Leung","family":"Ng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vernita","family":"Gordon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia L.","family":"Komarova","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5432-206X","authenticated-orcid":false,"given":"Rich","family":"Olson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2024111506250617000_2024.11.11.623042v1.1","doi-asserted-by":"publisher","DOI":"10.1038\/nrmicro.2016.94"},{"key":"2024111506250617000_2024.11.11.623042v1.2","doi-asserted-by":"crossref","unstructured":"Ghannoum, M. , Parsek, M. , Whiteley, M. & Mukherjee, P .
