Disease-resistant crops have the potential to reduce crop losses. This Review discusses how advances in genetic and genomic technologies are contributing to efforts by plant breeders to generate durable, broad-spectrum disease resistance in crop plants.
Characterizing the essentiality of human genes provides insights into gene function and genome evolution and facilitates the clinical interpretation of genetic variants. This article analyses essentiality metrics based on the statistical intolerance to loss-of-function mutations in human population sequencing studies and discusses commonalities and distinctions relative to data sets from knockout mice and functional genomics screens in human cell culture. Implications for disease genetics and extrapolation to non-coding regions are also discussed.
Sexual conflict is thought to increase population genetic diversity though balancing selection, which has important evolutionary implications. This Review discusses how population genomic approaches are contributing to a deeper understanding of sexual conflict and how it is resolved.
Identifying which genes in a genome are essential for survival has been a long-standing goal of geneticists. This Review discusses our evolving understanding of cellular gene essentiality across diverse organisms. It describes how essentiality is often non-absolute but is instead dependent on the environment or genetic background and how this knowledge can be exploited therapeutically.
The DNA methyltransferase (DNMT) family comprises a conserved set of DNA-modifying enzymes. Recent studies have increased our understanding of how DNMT activity is regulated and revealed that, in addition to establishing and maintaining DNA methylation patterns, DNMT enzymes function in transcriptional silencing, transcriptional activation and post-transcriptional regulation.
Recent large-scale genome-wide association studies have identified numerous variants that are associated with obesity-relevant traits such as body mass index or body fat percentage. Here, the authors explore to what extent this genomic evidence matches the evidence from functional and mechanistic studies.
Despite being a single species, dogs represent nearly 400 breeds with substantial genetic, morphological and behavioural diversity. In this Review, Ostranderet al. discuss how genomics studies of dogs have enhanced our understanding of dog and human population history, the desired and unintended consequences of trait-based selective breeding, and potentially human-applicable insights into cancer, ageing, behaviour and neurological diseases.
