    Data yielded from RIViT-seq increased the number of sigma factor-gene pairs confirmed in Streptomyces coelicolor from 209 to 399. Here, grey arrows denote previously known regulation and red arrows are regulation identified by RIViT-seq; orange nodes mark sigma factors while gray nodes mark other genes. (Otani, H., Mouncey, N.J. Nat Commun 13, 3502 (2022). https://doi.org/10.1038/s41467-022-31191-w)
    Streamlining Regulon Identification in Bacteria
    Regulons are a group of genes that can be turned on or off by the same regulatory protein. RIViT-seq technology could speed up associating transcription factors with their target genes.

Combining profiling and genomics yields novel metabolites

Cyanobacteria’s ability to capture solar energy and fix CO2 holds promise for biotech applications The Science Researchers studied 10 different cyanobacteria to identify their secondary metabolites (compounds produced during normal cellular metabolism not directly involved in cell growth, that may play an important role in interactions outside the cell) and the genes linked to those… [Read More]

Student tools for hands-on genomics and bioinformatics lessons

Driven in part by the increased emphasis to give life sciences students hands-on experience in “real research,” the DOE Joint Genome Institute’s Genomics and Bioinformatics Education Program developed a series of educational modules for undergraduate programs to explore and annotate publicly available microbial genome datasets. Known collectively as the Integrated Microbial Genomes Annotation Collaboration Toolkit… [Read More]

Cheryl Kerfeld on IMG-ACT in The Scientist

  “Bioinformatics has become such an integral part of research. And being able to do this, to use these tools in an informed way and in a way that’s somewhat discerning . . . is really important,” explains Cheryl Kerfeld, director of the Genomics and Bioinformatics Education Program at the Department of Energy’s Joint Genome… [Read More]

DOE JGI’s IMG/M data system in Berkeley Lab’s release on the Human Microbiome Project

Berkeley Lab’s role in mapping the human microbiome revolves around big data, both analyzing it and making it available for scientists to use worldwide…. Berkeley Lab scientists developed and maintain a comparative analysis system called the Integrated Microbial Genomes and Metagenomes for the Human Microbiome Project (IMG/M HMP). It allows scientists to study the human microbiome… [Read More]

Comparative genomics method to tag novel nitrogen-fixation genes

Nitrogen is crucial for plant growth but plants cannot harness it directly from the atmosphere. In the United States, legume crops such as soybeans and peas rely on nitrogen fertilizers to boost yields; in 2007, 13 million tons of industrially-produced fertilizers were applied. Soil bacteria such as Sinorhizobiummeliloti have a symbiotic relationship with plant hosts… [Read More]

Bioinformatics challenges for metagenomic analyses

There are more microbes in, on and around the planet than there are stars in the sky. However, the vast majority of these microorganisms have not yet been studied, in part because many of them do not thrive when moved out of their natural environment. A spoonful of soil contains a complex and diverse microbial… [Read More]

New tools for the IMG/M analysis system

Since the initial release of the Integrated Microbial Genomes with Microbiome samples (IMG/M) system in 2007 to support the comparative analysis of metagenomic data sets, DOE JGI researchers have made several updates in order to keep pace with the rapid increase in data set generation due to advances in sequencing technologies. As reported by researchers… [Read More]

A metagenomic approach to analyzing rice endophytes

During the call for 2012 proposals for the DOE JGI’s Community Sequencing Program, one of the areas of focus researchers were asked to consider was that of plant-microbe interactions. Microbes that live in plants or in the rhizosphere where plant roots and soil interact can play crucial roles in plant health. This is of particular… [Read More]
