The aim of this study was to identify the presence of acidocalcisomes in the plant trypanosomatid Phytomonas françai. Electron-dense organelles of P. françai were shown to contain large amounts of oxygen, sodium, magnesium, phosphorus, potassium, calcium, iron, and zinc as determined by X-ray microanalysis, either in situ or when purified using iodixanol gradient centrifugation or by elemental mapping. The presence of iron is not common in other acidocalcisomes. In situ, but not when purified, these organelles showed an elongated shape differing from previously described acidocalcisomes. However, these organelles also possessed a vacuolar H+- pyrophosphatase (V-H+-PPase) as determined by biochemical methods and by immunofluorescence microscopy using antibodies against the enzyme. Together, these results suggest that the electron-dense organelles of P. françai are homologous to the acidocalcisomes described in other trypanosomatids, although with distinct morphology and elemental content.</dcterms:abstract> <dc:contributor>Docampo, Roberto</dc:contributor> <dc:creator>Vercesi, Anibal</dc:creator> <dc:creator>Plattner, Helmut</dc:creator> <dcterms:title>Acidocalcisomes of Phytomonas françai possess distinct morphological characteristics and contain iron</dcterms:title> <dc:creator>Rodrigues, Claudia O.</dc:creator> <dc:contributor>Plattner, Helmut</dc:contributor> <dc:creator>Hentschel, Joachim</dc:creator> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/7335"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:33:38Z</dc:date> <dc:rights>terms-of-use</dc:rights> <dc:creator>Souza, Wanderley de</dc:creator> <dc:format>application/pdf</dc:format> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:33:38Z</dcterms:available> <dc:contributor>Hentschel, Joachim</dc:contributor> </rdf:Description> </rdf:RDF>
