Physiologia plantarumPhysiol PlantStrategies for severe drought survival and recovery in a Pyrenean relict species.276-29010.1111/ppl.13072In the context of future climate change new habitats will be threatened and unique species will be forced to develop different strategies to survive. Saxifraga longifolia Lapeyr. is an endemic species from the Pyrenees with a very particular habitat. We explored the capacity and strategies of S. longifolia plants to face different severities of drought stress under both natural conditions and controlled water stress followed by a re-watering period of 20?days. Our results showed a role for abscisic acid (ABA), salicylic acid (SA) and cytokinins (CKs) in plant survival from drought stress, and as the stress increased, ABA lost significance and SA appeared to be more associated with the response mechanisms. Moreover, photo-oxidative stress markers revealed that both xanthophyll cycles played a photoprotection role with a stronger participation of the lutein epoxide cycle as the stress was more intense. Severe drought decreased the maximum efficiency of photosystem II (Fv /Fm ) below 0.45, being this the limit to survive upon rewatering. Overall, our results proved different strategies of S. longifolia plants to cope with drought stress and suggested a Fv /Fm threshold to predict plant survival in high-mountain environments.© 2020 Scandinavian Plant Physiology Society.CotadoAlbaAhttps://orcid.org/0000-0003-3884-0390Department of Evolutionary Biology, Ecology and Environmental Sciences, Faculty of Biology, University of Barcelona, Barcelona, 08028, Spain.Munné-BoschSergiShttps://orcid.org/0000-0001-6523-6848Department of Evolutionary Biology, Ecology and Environmental Sciences, Faculty of Biology, University of Barcelona, Barcelona, 08028, Spain.Pintó-MarijuanMartaMhttps://orcid.org/0000-0002-9865-8438Department of Evolutionary Biology, Ecology and Environmental Sciences, Faculty of Biology, University of Barcelona, Barcelona, 08028, Spain.engBFU2015-64001-PSpanish GovernmentJournal Article20200405DenmarkPhysiol Plant12563220031-93170Cytokinins0Photosystem II Protein Complex059QF0KO0RWater72S9A8J5GWAbscisic AcidO414PZ4LPZSalicylic AcidIMAbscisic AcidanalysisCytokininsanalysisDroughtsPhotosystem II Protein ComplexphysiologySalicylic AcidanalysisSaxifragaceaephysiologyStress, PhysiologicalWater201909162020020420202206020209260202022060ppublish3207264510.1111/ppl.13072References, 2020</i></font><br><font color=#008000>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0<br></font></span><br>2.  <a href=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0 class=title>Plasticity in the growth habit prolongs survival at no physiological cost in a monocarpic perennial at high altitudes.</a><a href=http://ubio.org/tools/linkit.php?map%5B%5D=all&link_type=2&url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0><img src=linkit.png border=0 title='LinkIT' alt='LinkIT'></a> <br><span class=j>Cotado A, Munné-Bosch S<br><font color=gray><i>Annals of botany, 2020</i></font><br><font color=#008000>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0<br></font></span><br>3.  <a href=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0 class=title>Adaptation of the Long-Lived Monocarpic Perennial <b>Saxifraga longifolia</b> to High Altitude.</a><a href=http://ubio.org/tools/linkit.php?map%5B%5D=all&link_type=2&url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0><img src=linkit.png border=0 title='LinkIT' alt='LinkIT'></a> <br><span class=j>Munné-Bosch S, Cotado A, Morales M, Fleta-Soriano E, Villellas J, Garcia MB<br><font color=gray><i>Plant physiology, 2016</i></font><br><font color=#008000>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0<br></font></span><br></table></tr></table></td><script src="http://www.google-analytics.com/urchin.js" type="text/javascript"> </script> <script type="text/javascript"> _uacct = "UA-634822-1"; urchinTracker(); </script> </BODY> </HTML>
