Sequence Genome Fungus

A team of researchers from Imperial College London, the University of Oxford and CABI has successfully sequenced the genome of Alexander Fleming’s original fungal strain behind the discovery of penicillin, now classified as Penicillium rubens, and compared it to those of two ‘high producing’ industrial strains of Penicillium rubens and …

Transparent Squid

A team of researchers from the Marine Biological Laboratory, Harvard University and St. Mary’s College of Maryland has demonstrated efficient gene knockout in the longfin inshore squid (Doryteuthis pealeii) using CRISPR-Cas9 gene-editing system. Crawford et al demonstrated that squid genes can be efficiently disrupted using the CRISPR-Cas9 system. Image credit: …
