Complete Genome Sequence of Mycobacteriophage Joy99.

Joy99 is a siphoviral mycobacteriophage with a 59,837-base pair double-stranded DNA genome and is predicted to contain 97 protein-coding genes and a single tRNA gene. Joy99 was isolated in Saint Louis, MO, and annotated by students at Bluff Dale High School in community engagement with Tarleton State University.

Complete Genome Sequence of Cluster O Mycobacterium smegmatis Bacteriophage Ryadel.

Mycobacteriophage Ryadel is a newly isolated cluster O Siphoviridae bacteriophage, characterized by an unusual prolate capsid, containing a 72,658-base-pair double-stranded DNA genome with 132 predicted protein-coding genes. Conserved among cluster O bacteriophages, the Ryadel genome contains 31 copies of a unique 17-bp sequence with dyad symmetry.
