Tandem repeats are a large source of genetic variation but are challenging to analyse and have been missing from most genome-wide studies. Results now suggest that systematic incorporation of tandem repeats into complex trait analyses is likely to yield a rich source of causal variants and new biological insights. In this Comment, Lamkin and Gymrek discuss recent results that suggest that the systematic incorporation of tandem repeats into complex trait analyses will yield a rich source of causal variants and new biological insights.

Crop improvement by genome editing involves the targeted alteration of genes to improve plant traits, such as stress tolerance, disease resistance or nutritional content. Techniques for the targeted modification of genomes have evolved from generating random mutations to precise base substitutions, followed by insertions, substitutions and deletions of small DNA fragments, and are finally starting to achieve precision manipulation of large DNA segments. Recent developments in base editing, prime editing and other CRISPR-associated systems have laid a solid technological foundation to enable plant basic research and precise molecular breeding. In this Review, we systematically outline the technological principles underlying precise and targeted genome-modification methods. We also review methods for the delivery of genome-editing reagents in plants and outline emerging crop-breeding strategies based on targeted genome modification. Finally, we consider potential future developments in precise genome-editing technologies, delivery methods and crop-breeding approaches, as well as regulatory policies for genome-editing products. Targeted genome modification using CRISPR–Cas genome editing, base editing or prime editing is driving base research in plants and precise molecular breeding. The authors review the technological principles underlying these methods, approaches for their delivery in plants, and emerging crop-breeding strategies based on targeted genome modification.

Genome sequences largely determine the biology and encode the history of an organism, and de novo assembly — the process of reconstructing the genome sequence of an organism from sequencing reads — has been a central problem in bioinformatics for four decades. Until recently, genomes were typically assembled into fragments of a few megabases at best, but now technological advances in long-read sequencing enable the near-complete assembly of each chromosome — also known as telomere-to-telomere assembly — for many organisms. Here, we review recent progress on assembly algorithms and protocols, with a focus on how to derive near-telomere-to-telomere assemblies. We also discuss the additional developments that will be required to resolve remaining assembly gaps and to assemble non-diploid genomes. In this Review, Li and Durbin discuss how to generate telomere-to-telomere assemblies for large haploid or diploid genomes using currently available data types and algorithms, and outline remaining challenges in resolving highly repetitive sequences and polyploid genomes.

Proper regulation of mRNA production in the nucleus is critical for the maintenance of cellular homoeostasis during adaptation to internal and environmental cues. Over the past 25 years, it has become clear that the nuclear machineries governing gene transcription, pre-mRNA processing, pre-mRNA and mRNA decay, and mRNA export to the cytoplasm are inextricably linked to control the quality and quantity of mRNAs available for translation. More recently, an ever-expanding diversity of new mechanisms by which nuclear RNA decay factors finely tune the expression of protein-encoding genes have been uncovered. Here, we review the current understanding of how mammalian cells shape their protein-encoding potential by regulating the decay of pre-mRNAs and mRNAs in the nucleus. In this Review, the authors summarize our current understanding of nuclear pre-mRNA and mRNA decay pathways. They describe how aberrantly processed mRNAs are targeted for decay in the nucleus and how this process is regulated to finely control gene expression.

Long non-coding RNAs (lncRNAs) are emerging as a major class of gene products that have central roles in cell and developmental biology. Natural antisense transcripts (NATs) are an important subset of lncRNAs that are expressed from the opposite strand of protein-coding and non-coding genes and are a genome-wide phenomenon in both eukaryotes and prokaryotes. In eukaryotes, a myriad of NATs participate in regulatory pathways that affect expression of their cognate sense genes. Recent developments in the study of NATs and lncRNAs and large-scale sequencing and bioinformatics projects suggest that whether NATs regulate expression, splicing, stability or translation of the sense transcript is influenced by the pattern and degrees of overlap between the sense–antisense pair. Moreover, epigenetic gene regulatory mechanisms prevail in somatic cells whereas mechanisms dependent on the formation of double-stranded RNA intermediates are prevalent in germ cells. The modulating effects of NATs on sense transcript expression make NATs rational targets for therapeutic interventions. In this Perspective, Werner and colleagues discuss the many potential mechanisms by which natural antisense transcripts (NATs) can regulate expression of their complementary sense transcripts, the biological implications of their regulatory effects and the potential of NATs for therapeutic applications.
