US, Swedish Researchers Publish New Tree Gene Database

NEW YORK, Sept. 7 (GenomeWeb News) - Scientists from Oregon State University in Corvallis and the Umea Plant Science Center at Umea University in Sweden announced yesterday the publication of a new database of many of the most important genes in a tree genome.


The database describes about 102,000 sequences of the most commonly expressed genes in the genus Populus, which includes cottonwoods and aspens. The study, which was published in the Sept. 7 online edition of the Proceedings of the National Academy of Sciences, also compared many of the gene sequences to those found in Arabidopsis, one of the most commonly used plants for genetic research.

Octopus Brain Complexity Linked to MicroRNA Expansions

Investigators saw microRNA gene expansions coinciding with complex brains when they analyzed certain cephalopod transcriptomes, as they report in Science Advances.

Study Tracks Outcomes in Children Born to Zika Virus-Infected Mothers

By following pregnancy outcomes for women with RT-PCR-confirmed Zika virus infections, researchers saw in Lancet Regional Health congenital abnormalities in roughly one-third of live-born children.

Team Presents Benchmark Study of RNA Classification Tools

With more than 135 transcriptomic datasets, researchers tested two dozen coding and non-coding RNA classification tools, establishing a set of potentially misclassified transcripts, as they report in Nucleic Acids Research.

Breast Cancer Risk Related to Pathogenic BRCA1 Mutation May Be Modified by Repeats

Several variable number tandem repeats appear to impact breast cancer risk and age at diagnosis in almost 350 individuals carrying a risky Ashkenazi Jewish BRCA1 founder mutation.
