In Arabidopsis, a natural variant of the ELF3 protein, which originated in Central Asia, is less likely to accumulate in the nucleus, and causes the circadian clock to run faster and be less responsive to environmental cues.

Genetic incompatibilities are common and widely distributed throughout the genomes of swordtail fish, and prevent the regions of the genome around them from being exchanged between different species.

Individual scientists, scientific communities and scientific journals can do more to assess the publication of irreproducible results, to promote good science, and to increase the efficiency with which the scientific community self-corrects.

A general framework captures the evolutionary routes leading to the formation and progression of tumors.

The zebrafish is a premier model organism for biomedical research, with a rich array of tools and genomic resources, and combining these with a fuller appreciation of wild zebrafish ecology could greatly extend its utility in biological research.

Fully functional regulatory elements can arise rapidly from transposable elements via a novel route where non-allelic gene conversion can act to speed up the evolutionary fine-tuning of regulatory elements.

Environmental heterogeneity may contribute to the high levels of genetic variation in glucosinolate genes found in Arabidopsis thaliana.

In humans, non-crossover gene conversion events transmit GC alleles in 68% of cases and exhibit a complex pattern of multiple disconnected tracts clustered within 20–30 kilobase intervals.

The expression of small RNAs (or sRNAs) is regulated not only by mRNA expression, but also by their own regulatory elements and by sRNA biogenesis genes.

Embryonic gene expression is strongly influenced by maternal genetic variation and by embryonic variation that acts in cis but not in trans.
