Understanding species’ ability to acclimate to warming is crucial to better predict their future trends. Here, we study tolerance to warming in two key Mediterranean seagrasses, <i>Posidonia oceanica</i> and <i>Cymodocea nodosa</i>. Stress responses of shallow and deep plants were followed during and after short-term heat exposure in mesocosms by coupling photo-physiological measures with analysis of expression of photosynthesis and stress-related genes. Contrasting tolerance and capacity to heat acclimation were shown by shallow and deep <i>P. oceanica</i> ecotypes. While shallow plants acclimated through respiratory homeostasis and activation of photo-protective mechanisms, deep ones experienced photosynthetic injury and impaired carbon balance. This suggests that <i>P. oceanica</i> ecotypes are thermally adapted to local conditions and that Mediterranean warming will likely diversely affect deep and shallow meadow stands. On the other hand, contrasting mechanisms of heat-acclimation were adopted by the two species. <i>P. oceanica</i> regulates photosynthesis and respiration at the level of control plants while <i>C. nodosa</i> balances both processes at enhanced rates. These acclimation discrepancies are discussed in relation to inherent attributes of the two species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Physiological and molecular evidence of differential short-term heat tolerance in Mediterranean seagrasses","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-22 01:31:28.673638","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2016-06-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000378499100001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/srep28615"},"refs":null,"anarec":{"AnaID":259335,"PubliDate":2016,"Pagination":"13 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"6","Issue":"28615","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
