Chlamydomonas RNase J is the first member of this enzyme family that has endo- but no intrinsic 5' exoribonucleolytic activity. This questions its proposed role in chloroplast mRNA maturation. RNA maturation and stability in the chloroplast are contr

The biogenesis of the photosynthetic electron transfer chain in the thylakoid membranes requires the concerted expression of genes in the chloroplast and the nucleus. Chloroplast gene expression is subjected to anterograde control by a battery of nuc

Dual functions of the nucleus-encoded factor TDA1 in trapping and translation activation of atpA transcripts in Chlamydomonas reinhardtii chloroplasts

Publikováno v: The Plant Journal. 67:1055-1066

After endosymbiosis, organelles lost most of their initial genome. Moreover, expression of the few remaining genes became tightly controlled by the nucleus through trans-acting protein factors that are required for post-transcriptional expression (ma

The Q-cycle reviewed: How well does a monomeric mechanism of the bc1 complex account for the function of a dimeric complex?

Recent progress in understanding the Q-cycle mechanism of the bc(1) complex is reviewed. The data strongly support a mechanism in which the Q(o)-site operates through a reaction in which the first electron transfer from ubiquinol to the oxidized iron

Evidence for regulatory function of nucleus-encoded factors on mRNA stabilization and translation in the chloroplast

Autor: Jacqueline Girard-Bascou, Yves Choquet, Francis-André Wollman, Cécile Raynaud, Katia Wostrikoff, Christelle Loiselay, Richard Kuras

Publikováno v: Proceedings of the National Academy of Sciences. 104:9093-9098

A salient feature of organelle gene expression is the requirement for nucleus-encoded factors that act posttranscriptionally in a gene-specific manner. A central issue is to understand whether these factors are merely constitutive or have a regulator

We have characterized the biochemical nature and the function of PsbZ, the protein product of a ubiquitous open reading frame, which is known as ycf9 in Chlamydomonas and ORF 62 in tobacco, that is present in chloroplast and cyanobacterial genomes. A
