Understanding the genetic regulation underlying host–microbiota interactions is key to elucidating how microbial communities influence host metabolism, immunity, and physiology. In this context, the main objective of this study was to integrate genomic, transcriptomic, and microbial data to identify shared regulatory variants, highlight key microbial taxa, and prioritize biological pathways related to lipid metabolism, immune...

This study documents an ecotoxicological evaluation of bottom sediments ( n = 21) from a tropical lagoon complex performed in the Itaipu-Piratininga system (Rio de Janeiro State), an impacted urban tropical estuary. To achieve this purpose, three lines of evidence were adopted: sediment characterization, metal contamination and toxicity to tropical species (bioassays with mussels Perna perna , tanaids Kalliapseudes schubartii...

This work investigated how root anatomical traits, such as aerenchyma development, are related to root growth and volume and nutrient acquisition capacity in maize and sorghum plants under water limitation. Experiments were conducted in a greenhouse in a factorial 2 × 2 scheme (two plant species, maize and sorghum) and two water availabilities (well-irrigated and limited irrigation) with six replicates. Leaf gas exchange, grow...
