Proline, an osmoprotectant amino-acid, may contribute to alleviating the effects of cell and tissue dehydration. We studied five spring barley genotypes contrasting in their drought response, including two introgression lines, S42IL-143 and S42IL-141, harboring a Pyrroline-5-carboxylate synthase1- P5cs1 allele originating from the wild barley accession ISR42-8. We tested the hypothesis that barley genotypes harboring a wild allele at P5cs1 locus are comparatively more drought-tolerant at the reproductive stage by inducing proline accumulation in their immature spikes. At the booting stage, we subjected plants to well-watered and WS treatments until physiological maturity. Several morpho-physiological traits had significant genotype by treatment interaction and reduction under WS. Varying levels of genotypic proline accumulation and differences in WS tolerance were observed. Spike proline accumulation was higher than leaf proline accumulation for all genotypes under WS. Also, introgression lines carrying a wild allele at P5cs1 locus had a markedly higher spike and leaf proline content compared with the other genotypes. These introgression lines showed milder drought symptoms compared with elite genotypes, remained photosynthetically active under WS, and maintained their intrinsic water use efficiency. These combined responses contributed to the achievement of higher final seed productivity. Magnetic resonance imaging (MRI) of whole spikes at the soft dough stage showed an increase in seed abortion among the elite genotypes compared with the introgression lines 15 days after WS treatment. Our results suggest that proline accumulation at the reproductive stage contributes to the maintenance of grain formation under water shortage. 000890995 536__ $$0G:(DE-HGF)POF3-582$$a582 - Plant Science (POF3-582)$$cPOF3-582$$fPOF III$$x0 000890995 536__ $$0G:(DE-HGF)POF4-2171$$a2171 - Biological and environmental resources for sustainable use (POF4-217)$$cPOF4-217$$fPOF IV$$x1 000890995 588__ $$aDataset connected to CrossRef 000890995 7001_ $$0P:(DE-Juel1)129422$$aWindt, Carel W.$$b1$$ufzj 000890995 7001_ $$0P:(DE-Juel1)129425$$avan Dusschoten, Dagmar$$b2$$ufzj 000890995 7001_ $$0P:(DE-HGF)0$$aNaz, Ali A.$$b3 000890995 7001_ $$0P:(DE-HGF)0$$aFrei, Michael$$b4 000890995 7001_ $$0P:(DE-Juel1)143649$$aFiorani, Fabio$$b5$$eCorresponding author$$ufzj 000890995 773__ $$0PERI:(DE-600)2613694-6$$a10.3389/fpls.2021.633448$$gVol. 12, p. 633448$$p633448$$tFrontiers in plant science$$v12$$x1664-462X$$y2021 000890995 8564_ $$uhttps://juser.fz-juelich.de/record/890995/files/fpls-12-633448.pdf$$yOpenAccess 000890995 8767_ $$82020-0340207-4$$92021-01-25$$d2021-01-25$$eAPC$$jDeposit$$zUSD 2950 / nachtrag aus SAP 000890995 909CO $$ooai:juser.fz-juelich.de:890995$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire 000890995 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)173985$$aForschungszentrum Jülich$$b0$$kFZJ 000890995 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129422$$aForschungszentrum Jülich$$b1$$kFZJ 000890995 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129425$$aForschungszentrum Jülich$$b2$$kFZJ 000890995 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)143649$$aForschungszentrum Jülich$$b5$$kFZJ 000890995 9130_ $$0G:(DE-HGF)POF3-582$$1G:(DE-HGF)POF3-580$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lKey Technologies for the Bioeconomy$$vPlant Science$$x0 000890995 9131_ $$0G:(DE-HGF)POF4-217$$1G:(DE-HGF)POF4-210$$2G:(DE-HGF)POF4-200$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-2171$$aDE-HGF$$bForschungsbereich Erde und Umwelt$$lErde im Wandel – Unsere Zukunft nachhaltig gestalten$$vFür eine nachhaltige Bio-Ökonomie – von Ressourcen zu Produkten$$x0 000890995 9141_ $$y2021 000890995 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2021-01-28 000890995 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000890995 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bFRONT PLANT SCI : 2019$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000890995 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Blind peer review$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)1060$$2StatID$$aDBCoverage$$bCurrent Contents - Agriculture, Biology and Environmental Sciences$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central$$d2021-01-28 000890995 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2021-01-28 000890995 915pc $$0PC:(DE-HGF)0000$$2APC$$aAPC keys set 000890995 915pc $$0PC:(DE-HGF)0001$$2APC$$aLocal Funding 000890995 915pc $$0PC:(DE-HGF)0002$$2APC$$aDFG OA Publikationskosten 000890995 915pc $$0PC:(DE-HGF)0003$$2APC$$aDOAJ Journal 000890995 9201_ $$0I:(DE-Juel1)IBG-2-20101118$$kIBG-2$$lPflanzenwissenschaften$$x0 000890995 9801_ $$aFullTexts 000890995 980__ $$ajournal 000890995 980__ $$aVDB 000890995 980__ $$aUNRESTRICTED 000890995 980__ $$aI:(DE-Juel1)IBG-2-20101118 000890995 980__ $$aAPC
