Exploring the diversity and evolution of tombus-like viruses: phylogenetic analysis, recombination events, and suppressor protein homologs.

This study focuses on the phylogenetic analysis of previously unclassified tombus-like viruses, which are characterized by the presence of homologs of the suppressor protein p19. The primary objectives of this research were to investigate the evolutionary relationships among these viruses and to explore the impact of suppressor proteins and recombination events on their evolution. A dataset comprising 94 viral sequences was analyzed to achieve these goals.

Differential influence of molybdenum and tungsten on the growth of barley seedlings and the activity of aldehyde oxidase under salinity.

The influence of molybdenum, tungsten on germination and growth of barley Hordeum vulgare L. was studied. Results of this study revealed the differential effect of heavy metals on seedlings growth.

The involvement of ROS producing aldehyde oxidase in plant response to Tombusvirus infection.

The influence of Tomato bushy stunt virus (TBSV) infection on the activity and isoformic composition of aldehyde oxidase and catalase in Nicotiana benthamiana plants was investigated. It was shown that the infection of plants with TBSV results in enhancement of leaf aldehyde oxidase (AO) isoforms AO2 and AO3. Significantly enhanced levels of superoxide radical producing activity of AO isoforms were also detected.

Heat-induced formation of reactive oxygen species and 8-oxoguanine, a biomarker of damage to DNA.

Heat-induced formation of 8-oxoguanine was demonstrated in DNA solutions in 10(-3) M phosphate buffer, pH 6.8, by enzyme-linked immunosorbent assays using monoclonal antibodies against 8-oxoguanine. A radiation-chemical yield of 3.
