You can now retrieve genome data using the NCBI Datasetscommand-line tool and API by simply providing a BioProject accession. You can go directly from a BioProject accession to genome data even when the BioProject accession is the parent of multiple BioProjects (Figure 1).
We’ve improved BioProject to give you a better way to find all data from a specific project. We think you’ll love the new interface that lets you quickly choose the right BioProject with links to the data you want in other NCBI databases.
The updated BioProject browser makes it easier than ever to filter the data by a variety of attributes so you can quickly pick BioProjects that interest you.
This post is geared toward fungi researchers as well as RefSeq and BLAST users.
Fungi have unique characteristics that can make it difficult to identify and classify species based on morphology. To address these issues, Conrad Schoch, NCBI’s fungi taxonomist, and Barbara Robbertse, NCBI’s fungi RefSeq curator, in collaboration with outside mycology experts, are curating a set of fungal sequences from internal transcribed spacer (ITS) regions of the nuclear ribosomal RNA genes. This set of standard DNA sequences for fungal taxa not only addresses these difficulties in identifying and classifying fungal species by morphology, but is also essential for analyzing environmental (metagenomics) sequencing studies. The curated ITS sequences, described in a recent article in Database (PMC Free Article), all have associated specimen data and, when possible, are taken from sequences from type materials, ensuring correct species identification and tracking of name changes. This article will show you how to access these ITS sequences and search them using the specialized Targeted Loci BLAST service.
The fungal ITS sequences are a RefSeq Targeted Loci BioProject (PRJNA177353). As you may know, a BioProject is a collection of biological data related to a single initiative; in this case, the goal is to collect and curate fungal sequences from targeted loci – specific molecular markers such as protein coding or ribosomal RNA genes used for phylogenetic analysis.
