The characterization of functional redundancy and divergence between duplicate genes is an important step in understanding the evolution of genetic systems. Large-scale genetic network analysis in Saccharomyces cerevisiae provides a powerful perspective for addressing these questions through quantitative measurements of genetic interactions between pairs of duplicated genes, and more generally, through the study of genome-wide genetic interaction profiles associated with duplicated genes. We show that duplicate genes exhibit fewer genetic interactions than other genes because they tend to buffer one another functionally, whereas observed interactions are non-overlapping and reflect their divergent roles. We also show that duplicate gene pairs are highly imbalanced in their number of genetic interactions with other genes, a pattern that appears to result from asymmetric evolution, such that one duplicate evolves or degrades faster than the other and often becomes functionally or conditionally specialized. The differences in genetic interactions are predictive of differences in several other evolutionary and physiological properties of duplicate pairs.

Background: The estimated glucose disposal rate (eGDR) is a validated surrogate marker of insulin resistance. However, its association with stroke and dementia in nondiabetic populations remains insufficiently investigated.
Methods: This prospective cohort study included nondiabetic participants from the UK Biobank.

Background: Previous studies have suggested that the associations between ambient air pollution and atherosclerotic cardiovascular diseases (ASCVD) differ by genotype. A genome-wide approach provides a more comprehensive understanding of this relationship on a genomic scale.
Methods: Using data from ≈300 000 UK Biobank participants, we conducted a genome-wide interaction analysis on 10 745 802 variants.

The seed microbiota, a still underexplored component of plant-microbe interactions, plays a pivotal role in plant development and holds significant promise for advancing sustainable agriculture. By influencing essential processes such as germination, stress tolerance, nutrient acquisition and defence, seed-associated microbes offer unique advantages beyond those of soil- or rhizosphere-associated microbiomes. Notably, they are transmitted both vertically and horizontally; however, fundamental questions remain regarding their origin, ecological dynamics and functional roles across environments.

Aims: Diabetes is a global public health crisis, especially when it is accompanied by microvascular complications such as diabetic kidney disease (DKD). The purpose of this study was to explore the relationship between the combined lifestyle factors of diabetes patients and their joint effects with genetic risk and the risk of DKD.
Materials And Methods: We included individuals diagnosed with diabetes at baseline from UK Biobank.

Aroma differentiation is a key trait distinguishing citrus and other horticultural crops from staple crops. However, the mechanisms and sensory features by which distinctive and various citrus-like aroma in citrus remain poorly understood. In this study, we demonstrated that γ-terpinene determines tangerine-like aroma, affects consumer preference, and has pest-repellent properties.
