Recent studies reveal the important role of phosphonates mediated by prokaryotes in the marine P redox cycle. However, its bioavailability by eukaryotic phytoplankton is under debate. 2-Aminoethylphosphonic acid (2-AEP) and 2-amino-3-phosphonopropionic acid (2-AP3) are two biogenic phosphonates in the marine environment. Here, Thalassiosira pseudonana, a common diatom species in the ocean, is able to recover growth from P starvation when provided with 2-AEP and 2-AP3. Moreover, 2-AEP cultures exhibited a more similar growth rate at 12 \u00b0C than at 25 \u00b0C when compared with inorganic P cultures. The cellular stoichiometry of 2-AEP groups was further determined, the values of which are in-between the P-depleted and DIP-replete cultures. This study provides evidence that biogenic phosphonates could be adopted as alternative P sources to support diatom growth and may provide physiological adaptation.<\/jats:p>","DOI":"10.3390\/microorganisms12040761","type":"journal-article","created":{"date-parts":[[2024,4,10]],"date-time":"2024-04-10T03:07:48Z","timestamp":1712718468000},"page":"761","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Biogenic Phosphonate Utilization by Globally Distributed Diatom Thalassiosira\u00a0pseudonana"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-2098-1930","authenticated-orcid":false,"given":"Huilin","family":"Shu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of the Environment and Ecology, Xiamen University, Xiamen 361005, China"},{"name":"College of Life Sciences, Jiangxi Normal University, Nanchang 330022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6618-4226","authenticated-orcid":false,"given":"Yuan","family":"Shen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of Ocean and Earth Sciences, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongwei","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of Ocean and Earth Sciences, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueqiong","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of Ocean and Earth Sciences, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Ma","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of the Environment and Ecology, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7081-4198","authenticated-orcid":false,"given":"Xin","family":"Lin","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of Ocean and Earth Sciences, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/S0304-4203(96)00081-3","article-title":"Temporal variability in dissolved phosphorus concentrations in the subtropical North Pacific Ocean","volume":"56","author":"Karl","year":"1997","journal-title":"Mar.
