-Specific Bacteriophage BsXeu269p/3 Reduces the Spread of Bacterial Spot Disease in Pepper Plants.

The present study was focused on the pathosystem pepper plants ( L.)-phytopathogenic bacterium (wild strain 269p)-bacteriophage BsXeu269p/3 and the possibility of bacteriophage-mediated biocontrol of the disease. Two new model systems were designed for the monitoring of the effect of the phage treatment on the infectious process in vivo.

Long-term impact of sublethal atrazine perturbs the redox homeostasis in pea (Pisum sativum L.) plants.

Atrazine frequently contaminates soil, groundwater, rivers, and ponds. It is well know that acute doses (1-5 mM) of atrazine induce massive generation of singlet oxygen by blocking photosystem II. The sublethal concentrations of this herbicide, similar to those found in the environment, also reduce growth and disrupt photosynthesis in a long-term aspect, but exact mechanisms remain much uncertain.
