The gut microbiome plays a crucial role in intestinal maturation, metabolism, and immunoregulation, significantly influencing the host's health and growth performance. This review highlights the use of metagenomic techniques to the composition, function, and dynamic changes of the pig gut microbiota. Research has revealed that environmental and host factors, particularly diet, drive significant variations in microbial composition, which in turn shape host epigenetics through microbial components and metabolites. Furthermore, the strong correlation between the gut microbiota and host health presents opportunities for improving growth performance in the livestock industry.

High rates of mortality of the common cockle, , have occurred in the Wash Estuary, UK, since 2008. A previous study linked the mortalities to a novel genotype of , with a strong correlation between cockle moribundity and the presence of . Here, we characterize a novel iridovirus, identified by chance during metagenomic sequencing of a gradient purification of cells, with the presence also correlated to cockle moribundity.

Background And Aims: Crop wild relatives (CWRs) are key resources for enhancing agricultural resilience, providing genetic traits that can improve pest resistance, abiotic stress tolerance, and nutritional composition in domesticated crops. Within the mustard family (Brassicaceae) this is especially significant in the Brassiceae tribe, which includes economically important genera for agriculture such as Brassica and Sinapis. However, while breeding programmes have historically focused on major crops within this tribe, the potential of their wild relatives, particularly for underutilised and minor crops, remains insufficiently explored.

This study investigates the physicochemical, microbiological, and microstructural changes in soft wheat grain during germination under varying moisture conditions: moderately dry, moist, and wet. Pre-harvest sprouting can severely compromise grain quality and usability; however, understanding germination-induced changes offers insights into potential utilization strategies. Physical parameters-including thousand-kernel weight, test weight, and falling number-showed strong correlation with germination time, decreasing by 8.

The small GTPase Rho5 has been shown to be involved in regulating the Baker's yeast response to stress on the cell wall, high medium osmolarity, and reactive oxygen species. These stress conditions trigger a rapid translocation of Rho5 and its dimeric GDP/GTP exchange factor (GEF) to the mitochondrial surface, which was also observed upon glucose starvation. We here show that rho5 deletions affect carbohydrate metabolism both at the transcriptomic and the proteomic level, in addition to cell wall and mitochondrial composition.

A Gram-staining-negative, non-motile, aerobic, rod-shaped bacterium, designated 14752, was isolated from a saline lake in Xinjiang Uygur Autonomous Region, China. The strain was subjected to a taxonomic study using a polyphasic approach. Strain 14752 was able to grow at 4-40 ℃ (optimum 28 ℃), pH 6.
