• Microbial "Dark Matter"—unknown genes in microbial genomes.
• The process of annotation.
• An article about the "Y-ome" or understanding "uncharacterized" genes.
• The smallest independently growing (and engineered) bacterium, JCVI-syn3.0. It still has many "uncharacterized" but necessary genes.
• An essay on Enterococcus faecalis.
• Diseases caused by Enterococcus.
• The concept of the pathobiont.
• Dr. Arturo Casadevall's thoughts on the term "pathogen."
• The use of transposon mutagenesis to create "knock outs" of bacterial genes.
• Array transposon mutagenesis. Here is an article coauthored by Dr. Willett on that topic.
• The Alpha Fold program for predicting gene function.
• A webinar describing "Microbial Dark Matter" by Dr. Willett.
