Legumes are essential components of global cropping systems due to their nutritional value and contribution to sustainable agriculture. Among the regulatory molecules, small RNAs (sRNAs), particularly microRNAs (miRNAs), play crucial roles in plant development and in responses to biotic and abiotic stresses. miRNAs regulate genes involved in diverse developmental processes, including nodule formation, which is fundamental for...

Bacillus thuringiensis is a widely used biological control agent whose genomes contain a substantial proportion of coding sequences annotated as hypothetical proteins, limiting functional interpretation and hindering their exploitation in biotechnology and genetic engineering. Here, we present an integrative and reproducible bioinformatics workflow for the systematic annotation and prioritization of hypothetical proteins from...

Bacterial diseases associated with the Mollicutes class can lead to decreased milk production and reproductive disorders in cattle, causing significant economic losses and compromising animal welfare. This study aimed to investigate the presence of Mollicutes and Ureaplasma diversum in the reproductive tract of dairy cows and determine the associated risk factors, as well as identify circulating strains of Ureaplasma in herds....

The yellow clam, Amarilladesma mactroides, is an abundant component of the intertidal infauna of the southwestern Atlantic Ocean and an important source of food and income for local communities. In recent years, this species has been increasingly affected by anthropogenic and environmental pressures, contributing to the decline and collapse of several populations. In this study, we characterized the reproductive cycle of A. ma...

Mosses are non-vascular plants widely distributed across multiple habitats and capable of thriving in extreme environments, such as Antarctica and the Arctic. However, knowledge of the genetic, metabolic, and molecular diversity of polar species remains limited, necessitating a better understanding of their mechanisms of response to harsh conditions. In this context, axenic in vitro cultivation under laboratory conditions is a...

Autism Spectrum Disorder (ASD) is associated with neuroinflammation and oxidative stress that disrupt neurodevelopmental processes. Resveratrol (RSV) is a polyphenol with antioxidant and anti-inflammatory properties, but its poor bioavailability limits therapeutic use. This study investigated whether PEGylated liposomes encapsulating RSV (LipRSV) could modulate oxidative and behavioral alterations in a valproic acid (VPA)-indu...

Nannotrigona testaceicornis are essential pollinators for biodiversity maintenance and agricultural production. However, during foraging in agroecosystems, they may be exposed to residues of bioinsecticides used for pest management. Thus, this study evaluated the toxicity of the commercial product AzaMax® (azadirachtin) to the stingless bee N. testaceicornis . Adult worker bees were exposed to this bioinsecticide by contact an...

This study evaluates bioremediation using effective microorganisms (EM) to improve quality in the eutrophic Maricá Lagoon (RJ, Brazil). The intervention, implemented in late 2021, consisted of the regular application of EM in one of the lagoon’s main fluvial contributors: the Mumbuca-Ubatiba drainage basin. To evaluate bioremediation, physicochemical and biogeochemical variables were monitored in the water column and sediments...

Deforestation and environmental degradation increase the need for effective strategies to improve seedling establishment in ecological restoration programs, particularly under high irradiance conditions. Although processed kaolin particle film (PKPF) has been widely used to mitigate abiotic stress in agricultural crops, its potential application to native forest species during restoration remains poorly understood. This study...
