Functional redundancy revealed by the deletion of the mimivirus GMC-oxidoreductase genes

J.-M. Alempic, H. Bisio, A. Villalta, S. Santini, A. Lartigue, A. Schmitt, C. Bugnot, A. Notaro, L. BELMUDES, A. Adrait, O. Poirot, D. Ptchelkine, C. De Castro, Y. Coute, C. Abergel

The study shows that deleting GMC-oxidoreductase genes in mimiviruses does not impair genomic fiber or fibril layer formation, indicating functional redundancy.

A spectacular anomaly in the 4-mer composition of the giant pandoravirus genomes reveals a stringent new evolutionary selection process

O. Poirot, S. Jeudy, C. Abergel, J.-M. Claverie

The paper analyzes the 4-mer composition of pandoravirus genomes and identifies a unique absence of the tetranucleotide 'AGCT', suggesting a new evolutionary selection process.

Pandoravirus celtis illustrates the microevolution processes at work in the giant Pandoraviridae genomes

M. LEGENDRE, J.-M. ALEMPIC, N. PHILIPPE, A. LARTIGUE, S. JEUDY, O. POIROT, N. T. TA, S. NIN, Y. COUTE, C. ABERGEL, J.-M. CLAVERIE

The paper analyzes the Pandoravirus celtis genome to test the hypothesis that new protein-coding genes arise de novo from non-coding regions, finding ORFans and transposase insertions.
