Phage genomic DNA was isolated from the phage plaques of the 52-fragment assembly reactions (plaques 1–5 from 5 h reactions and plaques 6–10 from 15 h reactions) and sequenced using nanopore sequencing. Mutations differentiating the genomic sequences of the reconstituted phages compared to the reference T7 strain (GenBank: V01146.1) are shown.
Assembly reactions were designed to create phage genomes with 16 silent mutations to permit assembly with the BsmBI-type IIS restriction enzyme. All assembled genomes contained these mutations.
SNPs appeared in several of the assembled genomes; however, these mutations were not within 40 base pairs of assembly junction sites. More information on these mutations can be found in Tables S8, S9, and S10.
