It was hypothesized that RCS in barley (Hordeum vulgare L.) is (1) accelerated by exogenous ethylene exposure; (2) accompanied by differential expression of ethylene synthesis and signalling genes; and (3) associated with differential expression of programmed cell death (PCD) genes.MethodsGene expression of root segments from four barley genotypes with and without RCS was evaluated using quantitative real-time PCR (qRT-PCR). The progression of RCS was manipulated with root zone ethylene and ethylene inhibitor applications.Key ResultsThe results demonstrate that ethylene modulates RCS. Four genes related to ethylene synthesis and signalling were upregulated during RCS in optimal, low nitrogen and low phosphorus nutrient regimes. RCS was accelerated by root zone ethylene treatment, and this effect was reversed by an ethylene action inhibitor. Roots treated with exogenous ethylene had 35 and 46 % more cortical senescence compared with the control aeration treatment in seminal and nodal roots, respectively. RCS was correlated with expression of two genes related to programmed cell death (PCD).ConclusionsThe development of RCS is similar to root cortical aerenchyma formation with respect to ethylene modulation of the PCD process. 000845671 536__ $$0G:(DE-HGF)POF3-582$$a582 - Plant Science (POF3-582)$$cPOF3-582$$fPOF III$$x0 000845671 588__ $$aDataset connected to CrossRef 000845671 7001_ $$0P:(DE-Juel1)156560$$aWojciechowski, Tobias$$b1$$ufzj 000845671 7001_ $$0P:(DE-Juel1)144879$$aPostma, Johannes Auke$$b2 000845671 7001_ $$0P:(DE-HGF)0$$aBrown, Kathleen M$$b3 000845671 7001_ $$00000-0002-7265-9790$$aLynch, Jonathan P$$b4$$eCorresponding author 000845671 773__ $$0PERI:(DE-600)1461328-1$$a10.1093/aob/mcy059$$gVol. 122, no. 1, p. 95 - 105$$n1$$p95 - 105$$tAnnals of botany$$v122$$x1095-8290$$y2018 000845671 8564_ $$uhttps://juser.fz-juelich.de/record/845671/files/mcy059.pdf$$yRestricted 000845671 8564_ $$uhttps://juser.fz-juelich.de/record/845671/files/mcy059.gif?subformat=icon$$xicon$$yRestricted 000845671 8564_ $$uhttps://juser.fz-juelich.de/record/845671/files/mcy059.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000845671 8564_ $$uhttps://juser.fz-juelich.de/record/845671/files/mcy059.jpg?subformat=icon-180$$xicon-180$$yRestricted 000845671 8564_ $$uhttps://juser.fz-juelich.de/record/845671/files/mcy059.jpg?subformat=icon-640$$xicon-640$$yRestricted 000845671 8564_ $$uhttps://juser.fz-juelich.de/record/845671/files/mcy059.pdf?subformat=pdfa$$xpdfa$$yRestricted 000845671 909CO $$ooai:juser.fz-juelich.de:845671$$pVDB 000845671 915__ $$0StatID:(DE-HGF)0400$$2StatID$$aAllianz-Lizenz / DFG 000845671 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000845671 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium 000845671 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000845671 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000845671 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000845671 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bANN BOT-LONDON : 2015 000845671 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000845671 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000845671 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000845671 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000845671 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000845671 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000845671 915__ $$0StatID:(DE-HGF)1060$$2StatID$$aDBCoverage$$bCurrent Contents - Agriculture, Biology and Environmental Sciences 000845671 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000845671 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000845671 9141_ $$y2018 000845671 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)156560$$aForschungszentrum Jülich$$b1$$kFZJ 000845671 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)144879$$aForschungszentrum Jülich$$b2$$kFZJ 000845671 9131_ $$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$$x0 000845671 920__ $$lyes 000845671 9201_ $$0I:(DE-Juel1)IBG-2-20101118$$kIBG-2$$lPflanzenwissenschaften$$x0 000845671 980__ $$ajournal 000845671 980__ $$aVDB 000845671 980__ $$aI:(DE-Juel1)IBG-2-20101118 000845671 980__ $$aUNRESTRICTED
