This study identified two Arabidopsis (<italic>Arabidopsis thaliana</italic>) proteins, Tric1 and Tric2 (for tRNA import component), which on simultaneous inactivation by T-DNA insertion lines displayed a severely delayed and chlorotic growth phenotype and significantly reduced tRNA import capacity into isolated mitochondria. The predicted tRNA-binding domain of Tric1 and Tric2, a sterile-α-motif at the C-terminal end of the protein, was required to restore tRNA uptake ability in mitochondria of complemented plants. The purified predicted tRNA-binding domain binds the T-arm of the tRNA for alanine with conserved lysine residues required for binding. T-DNA inactivation of both Tric proteins further resulted in an increase in the in vitro rate of in organello protein synthesis, which was mediated by a reorganization of the nuclear transcriptome, in particular of genes encoding a variety of proteins required for mitochondrial gene expression at both the transcriptional and translational levels. The characterization of Tric1/2 provides mechanistic insight into the process of tRNA import into mitochondria and supports the theory that the tRNA import pathway resulted from the repurposing of a preexisting protein import apparatus.</p></abstract><counts><fig-count count="8"></fig-count><table-count count="0"></table-count><equation-count count="0"></equation-count><ref-count count="90"></ref-count><page-count count="20"></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">SAM</term><def id="def1"><p>sterile-α-motif</p></def></def-item><def-item><term id="term2">BN-PAGE</term><def id="def2"><p>blue native-PAGE</p></def></def-item><def-item><term id="term3">MS</term><def id="def3"><p>Murashige and Skoog</p></def></def-item><def-item><term id="term4">Col-0</term><def id="def4"><p>Columbia-0</p></def></def-item><def-item><term id="term5">EMSA</term><def id="def5"><p>electrophoretic mobility shift assay</p></def></def-item><def-item><term id="term6">FDR</term><def id="def6"><p>false discovery rate</p></def></def-item><def-item><term id="term7">PPR</term><def id="def7"><p>pentratricopeptide repeat</p></def></def-item><def-item><term id="term8">SD</term><def id="def8"><p>synthetic dextrose</p></def></def-item></def-list></glossary></notes></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
