Sequence annotation articles from across Nature Portfolio

The largest-ever study of alterations in the host’s microbiome and immune response during spaceflight shows shifts in the skin and oral microbiota during flight that are consistent across astronauts, with numerous changes in microbial gene expression that also correlate to host immune activity.

We developed the OMArk software package for evaluating protein-coding gene annotation quality. In addition to assessing the completeness of a proteome, OMArk estimates the overall quality of the gene set’s content, a feature that will help to improve public protein sequence data.

A recent study proposes an approach for identifying open reading frames that uses reference annotation to improve the accuracy of the detection.

A decade ago, the first bioinformatics pipelines to detect circular RNA molecules based on short-read sequencing data were published. Here, we show that dozens of such circular RNA detection tools differ vastly in their sensitivity but not in their specificity.
