[Phagolysates of cyanobacteria: their biocidal properties and use].

Data on the biological activity of cyanobacterial phagolysates were obtained in experiments. They concern the organisms of different evolutional level, such as some conventional pathogenic bacteria, plant and root parasitic nematodes and phytophagous insects. The authors suppose the specific mechanism of biocidal and inhibitory action of cyanobacteria and their phagolysates in respect to different living systems. These facts are very important for the elaboration of practical aspects of algal metabolites employment in agriculture and medicine.

Molecular mechanism of the alternative expression of the Chlorella virus CVK2 chitosanase gene.

A novel viral strategy for expression of two mRNAs from a single gene yielding two products with seemingly different functions (alternative gene expression) has be found. The vChta-1 gene of Chlorella virus CVK2 produced two functional chitosanase proteins with apparently different roles in viral infection: The larger 65-kDa chitosanase assembled into virion and presumably function at the beginning of infection, while the smaller 37-kDa enzyme remains in the host cytoplasm where it most likely aids in the digestion of the host cell wall prior to viral release. These predicted activities are essential for a cycle of viral infection. The dual expression of the vChta-1 gene most likely occurred by read-through into a downstream gene, ORF245.
