Abstract
Screening of Arabidopsis mutants with altered seed mucilage allowed identification of UUAT1, a Golgi-localized protein that transports UDP-glucuronic acid and plays a role in the biosynthesis of pectin.

Following synthesis in the cytosol, it is transported into the lumen of the Golgi apparatus, where it is converted to UDP-galacturonic acid (UDP-GalA), UDP-arabinose, and UDP-xylose. To identify the Golgi-localized <xref ref-type="def" rid="def4">UDP-GlcA</xref> transporter, we screened <italic>Arabidopsis thaliana</italic> mutants in genes coding for putative nucleotide sugar transporters for altered seed mucilage, a structure rich in the GalA-containing polysaccharide rhamnogalacturonan I. As a result, we identified <italic>UUAT1</italic>, which encodes a Golgi-localized protein that transports <xref ref-type="def" rid="def4">UDP-GlcA</xref> and UDP-GalA in vitro. The seed coat of <italic>uuat1</italic> mutants had less GalA, rhamnose, and xylose in the soluble mucilage, and the distal cell walls had decreased arabinan content. Cell walls of other organs and cells had lower arabinose levels in roots and pollen tubes, but no differences were observed in GalA or xylose contents. Furthermore, the GlcA content of glucuronoxylan in the stem was not affected in the mutant. Interestingly, the degree of homogalacturonan methylation increased in <italic>uuat1</italic>. These results suggest that this <xref ref-type="def" rid="def4">UDP-GlcA</xref> transporter plays a key role defining the seed mucilage sugar composition and that its absence produces pleiotropic effects in this component of the plant extracellular matrix.</p></abstract><counts><fig-count count="7"></fig-count><table-count count="1"></table-count><equation-count count="1"></equation-count><ref-count count="79"></ref-count><page-count count="15"></page-count></counts><custom-meta-group><custom-meta><meta-name> DJS Export </meta-name><meta-value>v1</meta-value></custom-meta></custom-meta-group></article-meta><notes><glossary><title>Glossary</title><def-list><def-item><term id="term1">GT</term><def id="def1"><p>glycosyltransferase</p></def></def-item><def-item><term id="term2">NST</term><def id="def2"><p>nucleotide sugar transporter</p></def></def-item><def-item><term id="term3">TPT</term><def id="def3"><p>triose phosphate translocator</p></def></def-item><def-item><term id="term4">UDP-GlcA</term><def id="def4"><p>UDP-glucuronic acid</p></def></def-item><def-item><term id="term5">UXS</term><def id="def5"><p>UDP-xylose synthase</p></def></def-item><def-item><term id="term6">RG-I</term><def id="def6"><p>rhamnogalacturonan I</p></def></def-item><def-item><term id="term7">HG</term><def id="def7"><p>homogalacturonan</p></def></def-item><def-item><term id="term8">SM</term><def id="def8"><p>soluble mucilage</p></def></def-item><def-item><term id="term9">AM</term><def id="def9"><p>adherent mucilage</p></def></def-item><def-item><term id="term10">DAP</term><def id="def10"><p>days after pollination</p></def></def-item><def-item><term id="term11">CDS</term><def id="def11"><p>coding sequence</p></def></def-item><def-item><term id="term12">LC-MS/MS</term><def id="def12"><p>liquid chromatography-tandem mass spectrometry</p></def></def-item><def-item><term id="term13">ER</term><def id="def13"><p>endoplasmic reticulum</p></def></def-item><def-item><term id="term14">PME</term><def id="def14"><p>pectin methylesterase</p></def></def-item><def-item><term id="term15">PACE</term><def id="def15"><p>carbohydrate gel electrophoresis</p></def></def-item><def-item><term id="term16">AIR</term><def id="def16"><p>alcohol-insoluble residue</p></def></def-item><def-item><term id="term17">TFA</term><def id="def17"><p>trifluoroacetic acid</p></def></def-item><def-item><term id="term18">HPAEC-PAD</term><def id="def18"><p>high-performance anion exchange chromatography with pulsed amperometric detection</p></def></def-item></def-list></glossary></notes></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
