We isolated novel temperature-sensitive mutants of spo0H, spo0H1 and spo0H5, having E61K and G30E amino-acid substitutions within the sigmaH protein, respectively, and located in the highly conserved region, "2", among prokaryotic sigma factors that participates in binding to core enzyme of RNA polymerase. These mutants showed a sporulation-deficient(More)
In the last 30 years some limited successes in alien ant control have been documented globally, and control programs remain challenging. Moreover, the potential non-target impacts of toxicants have not been well studied. We assessed the efficacy and non-target effects of multiple products containing the active compound fipronil in the attempted control of(More)
