Agricultural growers worldwide face significant challenges in promoting plant growth. This research introduces a green strategy utilizing nanomaterials to enhance crop production. While high concentrations of nanomaterials are known to be hazardous to plants, this study demonstrates that low doses of biologically synthesized zinc oxide nanoparticles (ZnO NPs) can serve as an effective regulatory tool to boost plant growth.

Cowpea (Vigna unguiculata) is recognized as a promiscuous legume in its symbiotic relationships with rhizobia, capable of forming associations with a wide range of bacterial species. Our study focused on assessing the diversity of bacterial strains present in cowpea nodules when inoculated with soils from six indigenous lands of Mato Grosso do Sul state, Central-Western Brazil, comprising the Cerrado and the Pantanal biomes, which are known for their rich diversity. The DNA profiles (BOX-PCR) of 89 strains indicated great genetic diversity, with 20 groups and 23 strains occupying single positions, and all strains grouped at a final similarity level of only 25%.

The GlnE enzyme, functioning as an adenylyltransferase/adenylyl-removing enzyme, plays a crucial role in reversible adenylylation of glutamine synthetase (GS), which in turn regulates bacterial nitrogen assimilation. Genomic analysis of Azorhizobium caulinodans ORS571 revealed an open reading frame encoding a GlnE protein, whose function in the free-living and symbiotic states remains to be elucidated. A glnE deletion mutant retained high GS activity even under nitrogen-rich conditions.

Protothecosis is a severe, emerging opportunistic infection caused by the saprophytic, achlorophyllous microalgae of the genus Prototheca. Though uncommon, human and animal cases are increasing worldwide, making awareness of this fungal-like pathogen important in both human and veterinary medicine. We report a fatal case of disseminated protothecosis caused by P.
