The interaction effect between mechanical impedance and P level was significant on most plant traits except for axial and lateral root length, suggesting an evident physical and nutritional interaction. Our findings provide valuable insights into the integrated effects of plants in response to both soil physical and nutritional stresses.…[Read more]

venge copper, namely utilization of methanobactin, a polypeptide that binds copper with high affinity and specificity. Previously the possibility that copper sequestration by methanotrophs may lead to alteration of cuproenzyme-mediated reactions in denitrifiers and consequently increase emission of potent greenhouse gas N2O has been suggested in…[Read more]

A high content of resistance and virulence genes was detected in both isolates. The novel KPC-49 variant, an Arg-163-Ser mutant of blaKPC-3, was detected in the isolate with resistance to ceftazidime-avibactam. Cloning experiments revealed that blaKPC-49 gene increases ceftazidime-avibactam MIC and decreases carbapenem MICs when using a porin…[Read more]
