How did PCI come about? Traditional scientific publishing faces many challenges, including publication costs. “Free to read and publish” is a design principle for Peer Community In: access to scientific evaluation should not depend on the ability to pay.

Haplotype-phased assemblies of the two poplar rust fungi species: Melampsora larici-populina and Melampsora allii-populina
Abstract. Dikaryotic rust fungi maintain two distinct haploid nuclei for most of their life cycle, making their large, repeat-rich genomes difficult to ass

📢 EffectorGeneP is finally here! Stop missing small, single-exon or orphan genes from your favourite pathogen genome. Current tools only annotate 15%-78% of effector genes, EffectorGeneP finds 95% - including the large AvrSr26 family in stem rust. #Bioinformatics 📖 www.biorxiv.org/content/10.6...

Glad to be part of the Data Reuse Consortium behind this @natmicrobiol.nature.com paper. Soon, ENA/NCBI submissions will include a Data Reuse Identifier (DRI) — like a DOI for papers. If you use microbiome sequencing data 🦠🧫🔬🧑‍💻, you need to read this 👇 www.nature.com/articles/s41...
