Azospirillum brasilense and organomineral fertilizer co-inoculated with Bradyrhizobium japonicumon oxidative stress in soybean by Fernanda Barros, Reginaldo de Camargo, Regina Maria Lana, Miguel Henrique Franco, Mayara Cristiana Stanger, Vanderley José Pereira, Ernane Lemes

“…Plant protection to stresses happened mainly by reductions in the superoxide dismutase activity, lipid peroxidation, and hydrogen peroxide concentration. The co-inoculation of A. brasilense with B. japonicum enhanced the proline activity at the V3 and R5 soybean phenological stage compared to A. brasilense inoculated alone.Conclusion The studied organomineral fertilizer is an efficient inoculant carrier for A. brasilense in soybean plants via seed treatment. …”

Error-Prone Translesion DNA Synthesis by Escherichia coli DNA Polymerase IV (DinB) on Templates Containing 1,2-dihydro-2-oxoadenine by Masaki Hori, Shin-Ichiro Yonekura, Takehiko Nohmi, Petr Gruz, Hiroshi Sugiyama, Shuji Yonei, Qiu-Mei Zhang-Akiyama

“…The fact that Pol IV preferred to insert dCTP opposite 2-oxodA suggests the mutagenic potential of 2-oxodA leading to A:T→G:C transitions. Hydrogen peroxide caused an ~2-fold increase in A:T→G:C mutations in E. coli, while the increase was significantly greater in E. coli overexpressing Pol IV. …”
