Evidence for increased fitness of a plant pathogen conferred by epigenetic variation

R. Gopalan-Nair, A. Coissac, L. Legrand, C. Lopez-Roques, Y. Pecrix, C. Vandecasteele, O. BOUCHEZ, X. Barlet, A. Lanois, A. Givaudan, J. Brillard, S. Genin, A. GUIDOT

This study shows epigenetic variation, specifically DNA methylation, contributes to rapid adaptation of the plant pathogen Ralstonia solanacearum to host plants.

Transcriptomic profiling reveals host-specific evolutionary pathways promoting enhanced fitness in the broad host range pathogen Ralstonia pseudosolanacearum

R. GOPALAN-NAIR, M. F. JARDINAUD, L. LEGRAND, C. LOPEZ-ROQUES, O. BOUCHEZ, S. GENIN, A. GUIDOT

This study shows that transcriptomic changes, not genetic ones, drive host-specific adaptation in Ralstonia pseudosolanacearum, revealing two distinct gene expression patterns linked to host genotype.

SDR enzymes oxidize specific lipidic alkynylcarbinols into cytotoxic protein-reactive species

P. Demange, E. Joly, J. Marcoux, P. R. A. Zanon, D. Listunov, P. Rulliere, C. Barthes, C. Noirot, J.-B. Izquierdo, K. Pradines, R. Hee, M. V. de Brito, M. Marcellin, R.-F. Serre, O. Bouchez, , S. Britton

The paper identifies SDR enzymes as bioactivators of lipidic alkynylcarbinols, converting them into cytotoxic electrophiles that modify proteins and induce cell death.

Cryptic patterns of speciation in cryptic primates: microendemic mouse lemurs and the multispecies coalescent

J. Poelstra, J. Salmona, G. P. Tiley, D. Schussler, M. B. Blanco, J. B. Andriambeloson, S. Manzi, C. R. Campbell, O. Bouchez, P. D. Etter, A. Iribar, P. A. Hohenlohe, K. E. Hunnicutt, E. A. Johnson, P. M. Kappeler, , A. D. Yoder

The paper investigates species boundaries in mouse lemurs using multispecies coalescent methods, finding that some previously recognized species are not distinct while an undescribed lineage is supported as a new species.
