Antiviral protection in the Pacific oyster Crassostrea (Magallana) gigas against OsHV-1 infection using UV-inactivated virus

B. Morga, M. Mege, N. Faury, L. Degremont, B. Petton, J.-F. Pepin, T. Renault, C. Montagnani

This study shows UV-inactivated OsHV-1 can prime the Pacific oyster immune system, increasing survival and blocking viral replication against OsHV-1 infection.

Epigenetic then genetic variations underpin rapid adaptation of oyster populations (Crassostrea gigas) to Pacific Oyster Mortality Syndrome (POMS)

J. Gawra, A. Valdivieso, F. Roux, M. Laporte, J. de Lorgeril, Y. Gueguen, M. Saccas, J.-M. Escoubas, C. Montagnani, D. Destoumieux-Garzon, F. Lagarde, M. Leroy, P. Haffner, B. Petton, C. Cosseau, , J. Vidal-Dupiol

This study shows that both genetic and epigenetic variations contribute to rapid adaptation of oyster populations to POMS, with epigenetic factors explaining a significant portion of phenotypic variation.

Genetic determinism of phage-bacteria coevolution in natural populations

D. Piel, M. Bruto, Y. Labreuche, F. Blanquart, S. Chenivesse, S. Lepanse, A. James, R. Barcia Cruz, J. Dubert, B. Petton, E. Lieberman, M. Wegner, F. Hussain, K. Kauffman, M. Polz, , F. Le Roux

The paper investigates phage-bacteria coevolution in natural populations, finding that phage and host genomes exhibit gene content variation and that negative-frequency dependent selection drives coevolutionary dynamics.
