Study of Molecular Karyotypes in Amoeboaphelidium protococcarum,the Endotrophic Parasite of Chlorophycean alga Scenedesmus

abstract：:In the present work, we provide biological evidences supporting the participation of NCW2 gene in the mechanism responsible for cell tolerance to polyhexamethylene biguanide (PHMB), an antifungal agent. The growth rate of yeast cells exposed to this agent was significantly reduced in ∆ncw2 strain and the mRNA levels o...
