A comprehensive analysis of the La-motif protein superfamily (2009)
Bousquet-Antonelli, Cécile, Deragon, Jean-Marc
The extremely well-conserved La motif (LAM), in synergy with the immediately following RNA recognition motif (RRM), allows direct binding of the (genuine) La autoantigen to RNA polymerase III primary...

Abstract Background Phosphorylation of eIF2α provides a key mechanism for down-regulating protein synthesis in response to nutrient starvation or stresses in mammalian and yeast cells. However, this...
A bona fide La protein is required for embryogenesis in Arabidopsis thaliana (2007)
Fleurdépine, Sophie, Deragon, Jean-Marc, Devic, Martine, Guilleminot, Jocelyne, Bousquet-Antonelli, Cécile
Searches in the Arabidopsis thaliana genome using the La motif as query revealed the presence of eight La or La-like proteins. Using structural and phylogenetic criteria, we identified two putative...
Deragon, Jean-Marc, Zhang, Xiaoyu
Short interspersed elements (SINEs) are a class of dispersed mobile sequences that use RNA as an intermediate in an amplification process called retroposition. The presence-absence of a SINE at a...
Synthesis and processing of tRNA-related SINE transcripts in Arabidopsis thaliana (2004)
Pélissier, Thierry, Bousquet-Antonelli, Cécile, Lavie, Laurence, Deragon, Jean-Marc
Despite the ubiquitous distribution of tRNA-related short interspersed elements (SINEs) in eukaryotic species, very little is known about the synthesis and processing of their RNAs. In this work, we...
The Evolutionary Origin and Genomic Organization of SINEs in Arabidopsis thaliana (2001)
Lenoir, Alain, Lavie, Laurence, Prieto, José-Luis, Goubely, Chantal, Cote, Jean-Charles, Pélissier, Thierry, ...
We have characterized the two families of SINE retroposons present in Arabidopsis thaliana. The origin, distribution, organization, and evolutionary history of RAthE1 and RAthE2 elements were studied...
Use of {gamma} irradiation to eliminate DNA contamination for PCR (1990)
Deragon, Jean-Marc, Sinnett, Daniel, Mitchell, Grant, Potier, Michel, Labuda, Damian
SINE Retroposons Can Be Used In Vivo as Nucleation Centers for De Novo Methylation
Arnaud, Philippe, Goubely, Chantal, Pélissier, Thierry, Deragon, Jean-Marc
SINEs (short interspersed elements) are an abundant class of transposable elements found in a wide variety of eukaryotes. Using the genomic sequencing technique, we observed that plant S1 SINE...

Lageix, Sébastien, Catrice, Olivier, Deragon, Jean-Marc, Gronenborn, Bruno, Pélissier, Thierry, Ramírez, Bertha Cecilia
Nanoviruses, multicomponent single-stranded DNA plant viruses, encode a unique cell cycle link protein, Clink, that interacts with retinoblastoma-related proteins (RBR). We have established...
Pouch-Pélissier, Marie-Noëlle, Pélissier, Thierry, Elmayan, Taline, Vaucheret, Hervé, Boko, Drasko, Jantsch, Michael F., ...
The proper temporal and spatial expression of genes during plant development is governed, in part, by the regulatory activities of various types of small RNAs produced by the different RNAi pathways....
On the Evolution and Expression of Chlamydomonas reinhardtii Nucleus-Encoded Transfer RNA Genes
Cognat, Valérie, Deragon, Jean-Marc, Vinogradova, Elizaveta, Salinas, Thalia, Remacle, Claire, Maréchal-Drouard, Laurence
In Chlamydomonas reinhardtii, 259 tRNA genes were identified and classified into 49 tRNA isoaccepting families. By constructing phylogenetic trees, we determined the evolutionary history for each...

Detailed Analysis of a Contiguous 22-Mb Region of the Maize Genome
Wei, Fusheng, Stein, Joshua C., Liang, Chengzhi, Zhang, Jianwei, Fulton, Robert S., Baucom, Regina S., ...
Most of our understanding of plant genome structure and evolution has come from the careful annotation of small (e.g., 100 kb) sequenced genomic regions or from automated annotation of complete...
Baucom, Regina S., Estill, James C., Chaparro, Cristian, Upshaw, Naadira, Jogi, Ansuya, Deragon, Jean-Marc, ...
Recent comprehensive sequence analysis of the maize genome now permits detailed discovery and description of all transposable elements (TEs) in this complex nuclear environment. Reiteratively...
