In addition, it is unknown whether semi-dwarfism in arabidopsis confers a growth advantage under water-limiting conditions compared with wild-type plants. The aim of this research was therefore to investigate whether semi-dwarfism has a pleiotropic effect in the root system and also whether semi-dwarfs might be more tolerant of water-limiting conditions.Methods The root systems of different arabidopsis semi-dwarfs and GA biosynthesis mutants were phenotyped in vitro using the GROWSCREEN-ROOT image-based software. Semi-dwarfs were phenotyped together with tall, near-related accessions. In addition, root phenotypes were investigated in soil-filled rhizotrons. Rosette growth trajectories were analysed with the GROWSCREEN-FLUORO setup based on non-invasive imaging.Key Results Mutations in the early steps of the GA biosynthesis pathway led to a reduction in shoot as well as root size. Depending on the genetic background, mutations at the GA5 locus yielded phenotypes characterized by decreased root length in comparison with related wild-type ones. The semi-dwarf accession Pak-3 showed the deepest root system both in vitro and in soil cultivation experiments; this comparatively deep root system, however, was independent of the ga5 loss-of-function allele, as shown by co-segregation analysis. When the accessions were grown under water-limiting conditions, semi-dwarf accessions with high growth rates were identified.Conclusions The observed diversity in root system growth and architecture occurs independently of semi-dwarf phenotypes, and is probably linked to a genetic background effect. The results show that there are no clear advantages of semi-dwarfism at low water availability in arabidopsis. 000203474 536__ $$0G:(DE-HGF)POF3-582$$a582 - Plant Science (POF3-582)$$cPOF3-582$$fPOF III$$x0 000203474 7001_ $$0P:(DE-Juel1)129373$$aNagel, Kerstin$$b1$$ufzj 000203474 7001_ $$0P:(DE-Juel1)129337$$aJansen, Marcus$$b2 000203474 7001_ $$0P:(DE-HGF)0$$aKlasen, Jonas R.$$b3 000203474 7001_ $$0P:(DE-Juel1)129343$$aKastenholz, Bernd$$b4$$ufzj 000203474 7001_ $$0P:(DE-Juel1)129290$$aBraun, Silvia$$b5$$ufzj 000203474 7001_ $$0P:(DE-Juel1)129285$$aBleise, Birgit$$b6$$ufzj 000203474 7001_ $$0P:(DE-Juel1)129291$$aBrehm, Thorsten$$b7$$ufzj 000203474 7001_ $$0P:(DE-HGF)0$$aKoornneef, Maarten$$b8 000203474 7001_ $$0P:(DE-Juel1)143649$$aFiorani, Fabio$$b9$$ufzj 000203474 773__ $$0PERI:(DE-600)1461328-1$$a10.1093/aob/mcv099$$n3$$p321-331$$tAnnals of botany$$v116$$x0305-7364$$y2015 000203474 8564_ $$uhttps://juser.fz-juelich.de/record/203474/files/Ann%20Bot-2015-Barboza-Barquero-321-31.pdf$$yOpenAccess 000203474 8564_ $$uhttps://juser.fz-juelich.de/record/203474/files/Ann%20Bot-2015-Barboza-Barquero-321-31.gif?subformat=icon$$xicon$$yOpenAccess 000203474 8564_ $$uhttps://juser.fz-juelich.de/record/203474/files/Ann%20Bot-2015-Barboza-Barquero-321-31.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000203474 8564_ $$uhttps://juser.fz-juelich.de/record/203474/files/Ann%20Bot-2015-Barboza-Barquero-321-31.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000203474 8564_ $$uhttps://juser.fz-juelich.de/record/203474/files/Ann%20Bot-2015-Barboza-Barquero-321-31.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000203474 8564_ $$uhttps://juser.fz-juelich.de/record/203474/files/Ann%20Bot-2015-Barboza-Barquero-321-31.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000203474 909CO $$ooai:juser.fz-juelich.de:203474$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000203474 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129373$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000203474 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129343$$aForschungszentrum Jülich GmbH$$b4$$kFZJ 000203474 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129290$$aForschungszentrum Jülich GmbH$$b5$$kFZJ 000203474 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129285$$aForschungszentrum Jülich GmbH$$b6$$kFZJ 000203474 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129291$$aForschungszentrum Jülich GmbH$$b7$$kFZJ 000203474 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)143649$$aForschungszentrum Jülich GmbH$$b9$$kFZJ 000203474 9131_ $$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$$x0 000203474 9141_ $$y2015 000203474 915__ $$0StatID:(DE-HGF)0400$$2StatID$$aAllianz-Lizenz / DFG 000203474 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000203474 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000203474 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000203474 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000203474 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bANN BOT-LONDON : 2014 000203474 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000203474 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000203474 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000203474 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000203474 915__ $$0StatID:(DE-HGF)1060$$2StatID$$aDBCoverage$$bCurrent Contents - Agriculture, Biology and Environmental Sciences 000203474 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000203474 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000203474 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000203474 920__ $$lyes 000203474 9201_ $$0I:(DE-Juel1)IBG-2-20101118$$kIBG-2$$lPflanzenwissenschaften$$x0 000203474 980__ $$ajournal 000203474 980__ $$aVDB 000203474 980__ $$aUNRESTRICTED 000203474 980__ $$aI:(DE-Juel1)IBG-2-20101118 000203474 9801_ $$aUNRESTRICTED 000203474 9801_ $$aFullTexts
