closely related to the model organism <italic>Chlamydomonas reinhardtii</italic>.
Although colorless, <italic>Polytomella</italic> spp. have a plastid, but it is still
unknown whether they harbor a plastid genome. We took a next generation sequencing
approach, along with transcriptome sequencing, to search for a plastid genome and an
associated gene expression system in <italic>Polytomella</italic> spp. Illumina
sequencing of total DNA from four <italic>Polytomella</italic> spp. did not produce
any recognizable plastid-derived reads but did generate a large number of
mitochondrial DNA sequences. Transcriptomic analysis of <italic>Polytomella
parva</italic> uncovered hundreds of putative nuclear-encoded, plastid-targeted
proteins, which support the presence of plastid-based metabolic functions, similar to
those observed in the plastids of other nonphotosynthetic algae. Conspicuously
absent, however, were any plastid-targeted proteins involved in the expression,
replication, or repair of plastid DNA. Based on these findings and earlier findings,
we argue that the <italic>Polytomella</italic> genus represents the first
well-supported example, to our knowledge, of a primary plastid-bearing lineage
without a plastid genome.</p></abstract><counts><page-count count="8"></page-count></counts></article-meta><notes><glossary><title>Glossary</title><def-list><def-item><term id="term1">ALA</term><def id="def1"><p>5-aminolevulinate</p></def></def-item><def-item><term id="term2">DNA-seq</term><def id="def2"><p>DNA sequencing</p></def></def-item><def-item><term id="term3">ptDNA</term><def id="def3"><p>plastid DNA</p></def></def-item><def-item><term id="term4">RNA-seq</term><def id="def4"><p>RNA sequencing</p></def></def-item><def-item><term id="term5">tRNA<sup>fMet</sup></term><def id="def5"><p>formylmethionyl-tRNA</p></def></def-item></def-list></glossary></notes></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
