The generation of reactive oxygen species (ROS) is an important mechanism of nanomaterial
toxicity. We found that Prussian blue nanoparticles (PBNPs) can effectively scavenge ROS …

The capacity to fix nitrogen is widely distributed in phyla of Bacteria and Archaea but has long
been considered to be absent from the Pseudomonas genus. We report here the complete …

A microscopic understanding of the growth mechanism of two-dimensional materials is of
particular importance for controllable synthesis of functional nanostructures. Because of the …

Plant growth promoting diazotrophs with the ability to associate with plant roots are in
common use as inoculants to benefit crop yield and to mitigate chemical nitrogen fertilization. …

Background Globally, about 20% of cultivated land is now affected by salinity. Salt tolerance
is a trait of importance to all crops in saline soils. Previous efforts to improve salt tolerance in …

The Hengduan Mountains (HDM) biodiversity hotspot exhibits exceptional alpine plant
diversity. Here, we investigate factors driving intraspecific divergence within a HDM alpine …

The feasibility of using base persulfate (PS) and coupled with other activation methods (heat,
ultrasonic and Fe 2 + single bondgluconate) was first explored for the removal of …

Background Biological nitrogen fixation is highly controlled at the transcriptional level by
regulatory networks that respond to the availability of fixed nitrogen. In many diazotrophs, …

Unlike most Pseudomonas, the root-associated bacterium Pseudomonas stutzeri A1501
fixes nitrogen after the horizontal acquisition of a nitrogen-fixing (nif) island. A genome-wide …

The HIV-1 epidemic in Shanghai is rapidly increasing. To better understand the HIV-1
genetic diversity and the mutations associated with resistance to protease inhibitors (PIs) and …
