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.

Commensalism in the Mimiviridae giant virus family

S. Jeudy, L. Bertaux, J.-M. Alempic, A. Lartigue, M. Legendre, L. Belmudes, S. Santini, N. Philippe, L. Beucher, E. G. Biondi, S. Juul, D. J. Turner, Y. Coute, J.-M. Claverie, C. Abergel

This study investigates the interaction network between a virophage, transpovirons, and their host giant viruses, revealing a form of commensalism where transpovirons use virophages to propagate without affecting the host virus's infectious cycle.

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.
