Antibiotic resistance genes (ARGs) in microorganisms and their indications for the nitrogen/sulfur cycle in the East China Sea sediments.

Antibiotic resistance genes (ARGs) are emerging environmental pollutants, posing an escalating threat to public health and environmental security worldwide. However, the relationship between ARGs and microbial communities in the environment, as well as their ecological effects on the microbe-mediated materials cycle remain unclear. In this study, we investigated the spatial distribution pattern, influence mechanism, relationship with microorganisms, and their effects on the elemental cycling of ARGs in East China Sea sediments.

Integration of ATAC-Seq and RNA-Seq Reveals the Role of in Red Light-Induced Fruit Ripening in Strawberry.

Light is an important environmental factor affecting the ripening and quality of strawberry fruit. Previous studies have shown that red light treatment can promote strawberry ripening. Gene expression is closely associated with chromatin openness, and changes in chromatin accessibility are crucial for the binding of transcription factors to downstream regulatory sequences.

Whole-genome resequencing landscape of adaptive evolution in Relict gull (Larus relictus).

Background: The relict gull (Larus relictus, Charadriiformes, Laridae) classified as vulnerable in the IUCN Red List is defined as a first-class national protected bird in China. However, our knowledge of the evolutionary history of L. relictus is limited.

Cumulus cells and the TNF-alpha signaling facilitate aging of ovine oocytes.

Post-maturation oocyte aging (PMOA) is known to significantly impair the developmental potential of oocytes; however, comprehensive studies on ovine PMOA remain limited. In mice, cumulus cells (CCs) accelerate oocyte aging by releasing cytokines, but the roles of CCs and cytokines in PMOA of domestic animals are poorly understood. This study aimed to elucidate the involvement of CCs and tumor necrosis factor (TNF)-α in the PMOA of ovine oocytes.
