New hypothesis on the ploidy of the hybrid species Phytopthora alni subsp. alni
2012
EA MERS CT3 Affiche (+ résumé mais sans mention de C. Revellin sur le résumé (oubli de C. Husson)); Alder decline caused by the Phytophthora alni complex is one of the most important diseases in natural ecosystems in Europe in the last 20 years. The emergence of Phytophthora alni subsp. alni (Paa), the pathogen responsible for the epidemics, is linked to an interspecific hybridization event between two parental species: Phytophthora alni subsp. multiformis (Pam) and Phytophthora alni subsp. uniformis (Pau). One of these parental species, Pau that has been isolated in several European countries and in North America, specifically in Alaska and Oregon, is exotic to Europe and a diploid species…
Study and characterization of the "Viable but non-culturable" state in Saccharomyces cerevisiae
2013
The viable but not culturable (VBNC) state has been studied in detail in bacteria. Bycontrast the VBNC state in other microorganisms, including particularly eukaryotes, has receivedmuch less attention. However, it has been suggested that in wine, Brettanomyces yeast cells mayenter a Viable But Not Culturable State, in particular in the presence of high, sulfur dioxide(SO2) concentration.To provide conclusive evidences for the existence of a VBNC state in yeast, especially in S.cerevisiae as a model organism, the capacity of different S cerevisiae strains to become viableand not cultivable after a sulfite stress with various concentrations of SO2 was studied by flowcytometry (FCM) using fluo…
