  • High-resolution structural determination of T4 infection machinery.

    • Main Results:

    • T4 gene expression involves complex regulation dependent on host RNA polymerase and phage-encoded proteins.
    • T4 DNA replication and recombination systems offer insights into genome stability and evolution.
    • Genomic analysis revealed details of tail fiber variation, lysis, and infection mechanisms.

    Conclusions:

    • Phage T4 is a crucial model for functional genomics, proteomics, and understanding genome evolution.
    • Despite extensive study, many T4 genes remain uncharacterized.
    • Comparative genomics of T4 family phages will enhance understanding of phage ecology and evolution.
