Unlike Arabidopsis (<italic>Arabidopsis thaliana</italic>) <xref ref-type="def" rid="def1">XyG</xref>, which contains galactosyl and fucosyl substituents, tomato (<italic>Solanum lycopersicum</italic>) <xref ref-type="def" rid="def1">XyG</xref> contains arabinofuranosyl residues. To investigate the biological function of these differing substituents, we used a functional complementation approach. Candidate glycosyltransferases were identified from tomato by using comparative genomics with known <xref ref-type="def" rid="def1">XyG</xref> galactosyltransferase genes from Arabidopsis. These candidate genes were expressed in an Arabidopsis mutant lacking <xref ref-type="def" rid="def1">XyG</xref> galactosylation, and two of them resulted in the production of arabinosylated <xref ref-type="def" rid="def1">XyG</xref>, a structure not previously found in this plant species. These genes may therefore encode <xref ref-type="def" rid="def1">XyG</xref> arabinofuranosyltransferases. Moreover, the addition of arabinofuranosyl residues to the <xref ref-type="def" rid="def1">XyG</xref> of this Arabidopsis mutant rescued a growth and cell wall biomechanics phenotype, demonstrating that the function of <xref ref-type="def" rid="def1">XyG</xref> in plant growth, development, and mechanics has considerable flexibility in terms of the specific residues in the side chains. These experiments also highlight the potential of reengineering the sugar substituents on plant wall polysaccharides without compromising growth or viability.</p></abstract><counts><page-count count="9"></page-count></counts></article-meta><notes><glossary><title>Glossary</title><def-list><def-item><term id="term1">XyG</term><def id="def1"><p>xyloglucan</p></def></def-item><def-item><term id="term2">XEG</term><def id="def2"><p>xyloglucan-specific endoglucanase</p></def></def-item><def-item><term id="term4">MALDI-TOF</term><def id="def4"><p>matrix-assisted laser-desorption ionization-time-of-flight</p></def></def-item><def-item><term id="term5">MS</term><def id="def5"><p>mass spectrometry</p></def></def-item><def-item><term id="term6">HPAEC</term><def id="def6"><p>high-performance anion-exchange chromatography</p></def></def-item><def-item><term id="term7">HPAEC-PAD</term><def id="def7"><p>high-performance anion-exchange chromatography with pulsed amperometric detection</p></def></def-item><def-item><term id="term8"><italic>m/z</italic></term><def id="def8"><p>mass-to-charge ratio</p></def></def-item><def-item><term id="term9">GT</term><def id="def9"><p>glycosyltransferase</p></def></def-item></def-list></glossary></notes></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
